cd0a9d3435 Add a checkout option to skip fsync
This is a better followup to dc9239dd7b
since I wanted to do fsync-less checkouts in rpm-ostree too, and
replicating the "turn off fsync temporarily" was in retrospect just a
hack.

We can simply add a boolean to the checkout options.

dc9239dd7b sysroot: Don't individually fsync dirs in checkout, rely on syncfs
Originally, a lot of the `fsync()` calls here were added for the
wrong reason - I was chasing a bug that ended up being the extlinux
bootloader not parsing 64 bit ext4 filesystems.  But since it looked
like corruption, I tried adding a lot more `fsync()` calls.

All we should have to do is use `syncfs()`.  If that doesn't work,
it's a kernel bug.

I'm making this change because skipping the individual fsyncs can be a
major performance win - it's easier for the FS to optimize, we do more
in parallel, etc.

5929ce9e0e repo: Add APIs for devino optimization between checkout -> commit
A fast way to generate new OSTree content using an existing
tree is to checkout (as hard links), add/replace files, then
call `ostree_repo_scan_hardlinks()`, then commit.

But `ostree_repo_scan_hardlinks()` scans the entire repo, which
can be slow if you have a lot of content.

All we really need is a mapping of (device,inode) -> checksum
just for the objects we checked out, then use that mapping
for commits.

This patch adds API so that callers can create a mapping via
`ostree_repo_devino_cache_new()`, then pass it to
`ostree_repo_checkout_tree_at()` which will populate it, and then
`ostree_repo_write_directory_to_mtree()` can consume it.

I plan to use this in rpm-ostree for package layering work.

Notes:
 - The old `ostree_repo_scan_hardlinks()` API still works.
 - I tweaked the cache to be a set with the checksum colocated with
   the key, to avoid a separate malloc block per entry.

5e7ed2dd8b grub2_generate: load sysroot before using it
The logic for checking which bootversion to use tries to access
sysroot->bootversion if the user didn't specify an explicit bootversion
on the command-line nor through the env var. However, at that point, the
sysroot object is not yet initialized, so it will always return 0, even
when it's 1.

This would cause e.g. `grub2-mkconfig` to have no output for the BLS
entries whenever the entries were under `/boot/loader.1`.

1f1bfbf711 fetcher: Lazily create tmp directory
The tmp directory is lazily created for each fetcher instance, since
it may require superuser permissions and some instances only need
_ostree_fetcher_request_uri_to_membuf() which keeps everything in

1810de2b51 deploy: Change large parts to be fd-relative, drop fsync
This is a continuation of earlier work to drop the individual fsync on
files/directories in favor of relying on `syncfs()` for speed.

As part of that cleanup, I'm porting it to be fd-relative.

I feel relatively confident about this change given that this area of
the code has notable test suite coverage, although that code runs as
non-root.

506a891e36 deploy: Find kernel/initramfs consistently from filesystem
I'm porting the deployment code to be fd-relative, but part of the
logic was using `GFile` to talk to `OstreeRepoFile` to determine the
"bootcsum" (boot config checksum) before checking out the file tree.

We can avoid having both code paths by checking out the tree first,
then looking at it on the filesystem.

f0b143ca8a pull: Push a temporary main context for sync requests
Given the previous commit, which isolates SoupSession in a separate
thread, it should be safe to start pushing a temporary main context
for synchronous requests again.

This partially reverts 84fe2ff, which partially reverted 9f3d586.

54066420cf fetcher: Move the SoupSession to a separate thread
Move the SoupSession to a separate thread with its own isolated main
context and main loop.  All interaction with the SoupSession occurs
by way of idle sources attached to the session's main context, which
execute on the session's thread.

This should solve the problem of running an asynchronous fetch request
synchronously by pushing a new thread-default main context and iterating
a main loop until the request completes.  Prior to this, the new thread-
default main context would interfere with the SoupSession's own async
processing.

af30fc764a fetcher: Add "config-flags" construct-only property
A lot of effort here just to avoid touching SoupSession directly in
ostree_fetcher_new().  The reason will become apparent in subsequent
commits.

Note this introduces generated enum/flags GTypes using glib-mkenums.
I could have just made the property type as plain integer, but doing
properties right will henceforth be easier now that the automake-fu
is established.

f771461b4a repo: Use per-transaction staging dir
Concurrent pulls break since we're sharing the staging directory for
all transactions in the repo. This makes us use a per-transaction directory.

However, in order for resumes to work we first look for existing
staging directories and try to aquire an exclusive lock for them. If
we can't find any staging directory or they are all already locked,
then we create a new one.

be19c88861 repo: Add _ostree_repo_allocate_tmpdir helper
This creates a subdirectory of the tmp dir with a selected prefix,
and takes a lockfile to ensure that nobody else is using the same directory.
However, if a directory with the same prefix already exists and is
not locked that is used instead.

The later is useful if you want to support some kind of resumed operation
on the tmpdir.

8ba90a3341 cmdline: Fatally error if the timestamp in a commit is invalid
Previously we were just ignoring this, which hid a bug in
an earlier commit that generated them.

Also change the `commit` program to use both APIs - this
involves extra code, but not too much.

This way, reverting the fix with this on top caused the test suite to
fail.  Adding an active test for this would need a custom test program
using the C API, or adding a cmdline flag to the client, neither of
which quite seemed worth it.
