21ebc7d21e Add sysroot.bootloader repo config key
The sysroot.bootloader key configures the bootloader
that OSTree uses when deploying a sysroot. Having this key
allows specifying behavior not to use the default bootloader
backend code, which is preferable when creating a first
deployment from the sysroot (#1774).

As of now, the key can take the values "auto" or "none". If
the key is not given, the value defaults to "auto".

"auto" causes _ostree_sysroot_query_bootloader() to be used
when writing a new deployment, which is the original behavior
that dynamically detects which bootloader to use.

"none" avoids querying the bootloader dynamically. The BLS
config fragments are still written to
sysroot/boot/loader/entries for use by higher-level software.

More values can be supported in future to specify a single
bootloader, different behavior for the bootloader code, or
a list of bootloaders to try.

dde3f1c0fb src/ostree: Add --group option to ostree config
Fetching value from a repo config using 'ostree config
get SECTIONNAME.KEYNAME' didn't work in some cases like
when having dots in Group Name entry.
As per Desktop entry file specification, Group Name
may contain all ASCII characters except for [ and ]
and control characters.
Link - https://specifications.freedesktop.org/desktop-entry-spec/desktop-entry-spec-1.1.html

Having --group option will help user to clearly specify
Group Name and get desired result.

It also adds test for ostree config get|set and bash
completion for --group option

ce58307757 deploy: Delete .updated file from /etc and /var on new deployments
Systemd units using ConditionNeedsUpdate run if the mtime of .updated in
the specified directory is newer than /usr. Since /usr has an mtime of
0, there's no way to have an older .updated file. Systemd units
typically specify ConditionNeedsUpdate=/etc or ConditionNeedsUpdate=/var
to support stateless systems like ostree.

Remove the file from the new deployment's /etc and the OS's /var
regardless of where they came from to ensure that these systemd units
run when booting new deployments. This will provide a method to run
services only on upgrade.

8fbf19c9f5 Make P2P API public (no longer experimental)
Currently the API that allows P2P operations (e.g. pulling an ostree ref
from a LAN or USB source) is hidden behind the configure flag
--enable-experimental-api. This commit makes the API public and makes
that flag essentially a no-op (leaving it in place in case we want to
use it again in the future). The P2P API has been tested over the last
several months and proven to work.

This means that since we're no longer using the "experimental" feature
flag, P2P builds of Flatpak will fail when using versions of OSTree from
this commit onwards, until Flatpak is patched in the near future. If you
want to build Flatpak < 0.11.8 with P2P enabled and link against OSTree
2018.6, you'll have to patch Flatpak.  However, since Flatpak won't yet
have a hard dependency on OSTree 2018.6, it needs a new way to determine
if the P2P API in OSTree is available, so this commit adds a "p2p"
feature flag. This way the feature set is more semantically correct than
if we had continued to use the "experimental" feature flag.

In addition to making the P2P API public, this commit makes the P2P unit
tests run by default, removes the f27-experimental CI instance that's no
longer needed, changes a few man pages to reflect the changes, and
updates the bash completion script to accept the new commands and
options.

6bf4b3e1d8 Add SPDX-License-Identifier to source files
SPDX License List is a list of (common) open source
licenses that can be referred to by a “short identifier”.
It has several advantages compared to the common "license header texts"
usually found in source files.

Some of the advantages:
* It is precise; there is no ambiguity due to variations in license header
  text
* It is language neutral
* It is easy to machine process
* It is concise
* It is simple and can be used without much cost in interpreted
  environments like java Script, etc.
* An SPDX license identifier is immutable.
* It provides simple guidance for developers who want to make sure the
  license for their code is respected

2b78df25f4 tests: Add a test case for path traversal in a dirtree
I was reading about a recent security issue with both EMC and VMWare:
https://arstechnica.com/information-technology/2018/01/emc-vmware-security-bugs-throw-gasoline-on-cloud-security-fire/

It's a classic path traversal problem, and that made me think more about our
handling of this in libostree.  Fortunately of course, not being new to
this rodeo, long ago I *did* consider path traversal.  Inside the pull
code, we call `ot_util_filename_validate()`.  Also, `fsck` does this too.

I have further followups here, but let's add some test cases for this. I crafted
a repository with a `../` in a dirtree object by patching libostree to inject
it, and that's included as a tarball.

This patch covers the two cases where we do already have checks; pulling
via HTTP, and in `fsck`.

4233b1db19 Support for booting without initramfs
Previously when initramfs-* was not found in a deployment's
boot directory, it was assumed that rootfs is prepared for
ostree booting by a kernel patch.

With this patch, the behaviour changes to be - if initramfs-*
is not found, assume that system is using a static
ostree-prepare-root as init process. Booting without initramfs
is a common use case on embedded systems. This approach is
also more convenient, than having to patch the kernel.

4273e670ea Add "pull --localcache-repo"
This is a lot like `git clone --reference`, but we chose "localcache" as the
term "reference" is already used.

The main use case I'm targeting this for is the Fedora Atomic Host installer
case where we embed the repo content in the installer, but we may want to
kickstart and download newer content. There, while we want to get a newer ref,
we can still use the local repo as an object cache, since we have it sitting
there in memory anyways.

Another case is where one has a host ostree (say e.g. Fedora Atomic
Workstation), and one wants to create a local archive mirror of FAH. Then one
can use `pull --reference /ostree/repo` and pull the common objects (e.g.
contents of `bash.rpm` etc.)

This functionality is planned to be used in Endless OS. We will create

a195888b0f lib/checkout: Fix regression in subpath for regular files
This is what caused the merge of
https://github.com/projectatomic/rpm-ostree/pull/652
to blow up, since https://github.com/ostreedev/ostree/pull/848
landed right before we tried to merge it.

When I was writing that PR I remember having an uncertain feeling
since we were doing a `mkdirat` above, but at the time I thought
we'd have test suite coverage...turns out we didn't.

For backwards compatibility, we need to continue to do a `mkdirat` here of the
parent. However...I can't think of a reason anyone would *want* that behavior.
Hence, let's add a special trick - if the destination name is `.`, we skip
`mkdirat()`. That way rpm-ostree for example can open a dfd for `/etc` and avoid
the `mkdir`.

Fold the subpath tests into `test-basic.sh` since it's not worth a separate
file. Add a test case for checking out a file.

c7efe01520 Add --enable-installed-tests=exclusive, fix installed case
The major reason to do this is that running tests *both* installed
and uninstalled in our CI is a mostly pointless waste of time.
Particularly given we have a few expensive tests.

We *do* have tests that only run uninstalled (since they require
the source code) like `test-symbols.sh`.

Hence, add `--enable-installed-tests=exclusive` to mean *only* do installed for
most tests.

We'll still have uninstalled coverage via the Travis/Debian configs, and we
could perhaps do another build with a subset of uninstalled tests, but I'm not
really concerned about it.

I'd like to do a renewed push for the InstalledTests model since
I feel it's just fundamentally better.  (`g-d-t-r` kind of sucks,
but then so does the automake runner).

Also while we're here - fix the CI to use the correct context,

511b31cfb5 checkout: Merge union/add logic for copies during checkout
We really have an astonishing variety of similar functions which write files and
symlinks. I was working on a different PR and the duplication between the
union-mode and add-mode/none-mode checkout functions bothered me.

I realized that the "handle EEXIST" tri-state maps directly to the
`GLnxLinkTmpfileReplaceMode`, so deduping things makes even more sense.

305db981d4 Add Coccinelle usage: one for blacklisting, one for patch collection
This is inspired by the [Coccinelle](http://coccinelle.lip6.fr/) usage
in systemd.  I also took it a bit further and added infrastructure
to have spatches which should never apply.  This acts as a blacklist.

The reason to do the latter is that coccinelle is *way* more powerful than the
regular expresssions we have in `make syntax-check`.

I started with blacklisting `g_error_free()` directly. The reason that's bad is
it leaves a dangling pointer.

7c8f95c86f Add basic tests for bare-user-only repo modes
This is somewhat complicated by such repos only properly supporting
some subset of file metadata (uid/gid 0, etc). We fix this by
always commiting with filters that make it work.

36b28cb4d2 upgrade: Add support for --pull-only and --deploy-only
This makes it easier to script downloading updates in the background,
and only do deployments just before rebooting.

Partially addresses https://github.com/ostreedev/ostree/issues/640

d894f609db oxidation: Add implementation of bupsplit in Rust
This is an initial drop of "oxidation", or adding implementation
of components in Rust.  The bupsplit code is a good target - no
dependencies, just computation.

Translation into Rust had a few twists -

 - The C code relies a lot on overflowing unsigned ints, and
   also on the C promotion rules for e.g. `uint8_t -> int32_t`
 - There were some odd loops that I introduced bugs in while
   translating...in particular, the function always returns `len`,
   but I mistakenly translated to `len+1`, resulting in an OOB
   read on the C side, which was hard to debug.

On the plus side, an off-by-one array indexing in the Rust code paniced nicely.

In practice, we'll need a lot more build infrastructure to make this work, such
as using `cargo vendor` when producing build artifacts for example. Also, Cargo
is yet another thing we need to cache.

Where do we go with this? Well, I think we should merge this, it's not a lot of
code. We can just have it be an alternative CI target. Should we do a lot more
right now? Probably not immediately, but I find the medium/long term prospects
pretty exciting!

d1f4d94720 tests: Add a big (many objects) pull
This would be more likely to tickle things like
https://github.com/ostreedev/ostree/issues/601
reliably.

Also, while working on the curl backend, I hit on the fact that curl doesn't
queue (by default, you can enable) and will happily create 20000+ concurrent TCP
connections if you try. Having this test would have made that more likely to
fail.
