7f88fddcd4 sysroot: Add concept of deployment "pinning" 📌
Example user story: Jane rebases her OS to a new major version N, and wants to
keep around N-1 even after a few upgrades for a while so she can easily roll
back. I plan to add `rpm-ostree rebase --pin` to opt-in to this for example.

Builds on the new `libostree-transient` group to store pinning state there.

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

See http://spdx.org for further reading.

bed931c91f build: Don't distribute generated man pages
We build them in "make" and clean them in "make clean", so there
doesn't seem much point in shipping them pre-generated in the tarball.

39918179d1 build: Actually distribute man page XML source
The make substitution pattern was wrong. The source files are
"ostree.xml", not "ostree.1.xml", for instance.

7adc943596 build: Distribute man page XML source
Without this, the manual pages can't actually be regenerated from a dist
tarball, and running make clean will remove all traces of them.

09238da065 admin: Add an unlock command, and libostree API
I'm trying to improve the developer experience on OSTree-managed
systems, and I had an epiphany the other day - there's no reason we
have to be absolutely against mutating the current rootfs live.  The
key should be making it easy to rollback/reset to a known good state.

I see this command as useful for two related but distinct workflows:

 - `ostree admin unlock` will assume you're doing "development".  The
   semantics hare are that we mount an overlayfs on `/usr`, but the
   overlay data is in `/var/tmp`, and is thus discarded on reboot.
 - `ostree admin unlock --hotfix` first clones your current deployment,
   then creates an overlayfs over `/usr` persistent
   to this deployment.  Persistent in that now the initramfs switchroot
   tool knows how to mount it as well.  In this model, if you want
   to discard the hotfix, at the moment you roll back/reboot into
   the clone.

Note originally, I tried using `rofiles-fuse` over `/usr` for this,
but then everything immediately explodes because the default (at least
CentOS 7) SELinux policy denies tons of things (including `sshd_t`
access to `fusefs_t`).  Sigh.

So the switch to `overlayfs` came after experimentation.  It still
seems to have some issues...specifically `unix_chkpwd` is broken,
possibly because it's setuid?  Basically I can't ssh in anymore.

But I *can* `rpm -Uvh strace.rpm` which is handy.

NOTE: I haven't tested the hotfix path fully yet, specifically
the initramfs bits.

355f8438ef Add an export builtin, and API to write to libarchive
At the moment I'm looking at using rpm-ostree to manage RPM inputs
which can then be converted into Docker images.  It's most convenient
if we can stream directly out of libostree rather than doing a
checkout + tar combination.

There are also backup/debugging etc. reasons to implement `export` as
well.

e9ccdd2d00 Import rofiles-fuse
While it's not strictly tied to OSTree, let's move
https://github.com/cgwalters/rofiles-fuse in here because:

 - It's *very* useful in concert with OSTree
 - It's tiny
 - We can reuse OSTree's test, documentation, etc. infrastructure

One thing to consider also is that at some point we could experiment
with writing a FUSE filesystem for OSTree.  This could internalize a
better equivalent of `--link-checkout-speedup`, but on the other hand,
the cost of walking filesystem trees for these types of operations is
really quite small.

But if we did decide to do more FUSE things in OSTree, this is a step
towards that too.

313b4720e8 build: Move man pages into man/
This is preparation for having 3 separate doc build systems (whee):

 - xsltproc for the man pages
 - gtk-doc for the API docs
 - mkdocs for a real manual
