"ostree pull" intermittently fails with a bus error on at least some
mipsel CPUs, and applying gdb to the resulting core dump does not produce
any useful information. Debugging help would be appreciated. (Mitigates:
#827473)
I was easily reproducing a hang on pulls with thousands of requests on
current git master. The initial symptom seemed to be that there are
multiple code paths where we don't invoke
`session_thread_process_pending_queue()`. We really need to do
that any time we remove something from the outstanding queue,
to ensure it gets filled again.
A further issue is that we were tying the lifecycle of the pending
object to the `GTask`, but the task could be unref'd from the main
thread (via a `GSource` on the main thread), and that introduced
threadsafety issues, because the hash table and other data suddenly
could be concurrently modified.
Both of these need to be fixed together. First, we introduce
`Arc<Pending>`, and ensure that both the main and worker threads hold
references.
Second, we ensure that we re-process the queue *immediately* whenever
a task is done, inside the worker thread, rather than doing it
incidentally via an unref. This architecture is quite similar to what
the outside pull code is doing.

For some reason I'm really not inclined to debug right now, `libtool`
is eating the `-fsanitize=address` argument when linking
`libreaddir-rand.so`, which causes failures since we're trying to
`LD_PRELOAD`.

It's unfortunate that in automake one has to explicitly include the globa
`$(AM_CFLAGS)` if one sets `CFLAGS`, and similarly for other variables.
I'm trying to use `-fsanitize=address`, and not including it was
causing linker failures.
We also weren't inheriting the global warnings etc., so I had to fix a
decl-after-statement.

The previous code was subject to a divide by zero if less than a
second had passed. Rework it so we only do the divide if more than a
second has passed.

We noticed the temp files being left over in ostree when (mistakenly)
trying to create refs with names in use by folders. This fix removes
temp files created by glnx_file_replace_contents_at on failure.

I find the "-z2" is really a long ago relic of the past when I changed
the format. We no longer have anything to do with the original
`archive`, so let's start allowing people to type `--mode=archive`
which just looks saner.
At some point later I'll update the docs too, but it'll be an annoying
transition period as we'll have to say "On older OSTree, use -z2" etc.

Added the ability to create a ref (much like a git tag) for an
existing commit through "ostree refs EXISTING --create=NEWREF".
Previously the only way to create a new ref was by creating a new commit,
but refs --create allows multiple refs to point to the same commit.
The command will fail if:
- None/more than one existing ref is specified
- The specified EXISTING tag does not exist, or was not specified
- The specified NEWREF already exists, or is the name of a folder
Add unit tests in tests-ref.sh to verify above functionality

Just noticed this while reading some code, we didn't have many manual
`out: close()` bits left, this pushes us over the edge to autocleanup
almost everywhere.

The filename of the real ostree executable could be either .libs/ostree
or .libs/lt-ostree.

Otherwise, during "make distcheck" it will be read-only (because it
is a copy of the read-only ${srcdir} with permissions preserved), and
deletion will fail during cleanup.

This avoids hard-coding the autogen-time ${srcdir} into our build
system, and might fix "make distcheck".
We don't need to specify ${srcdir} explicitly in the various variables,
because Automake always uses make's VPATH feature to look in both
${builddir} and ${srcdir} at build time.

It uses dlsym(). There's no point in being extra-portable here
because OSTree only targets Linux anyway.
