OstreeAsyncProgress currently does some contortions to try and avoid
allocating space for guints and guint64s (on 64-bit platforms), but this
means it uses two GHashTables. A GHashTable allocates 8 buckets even
when empty. Given that the largest usage of OstreeAsyncProgress in
libostree puts 13 uints and 5 uint64s in it, this optimisation does not
save significant (if any) memory.
Instead, change OstreeAsyncProgress to store values internally as
GVariants, and expose this with some new API:
• ostree_async_progress_get_variant()
• ostree_async_progress_set_variant()
Each GVariant is allocated on the heap. As they are immutable, they are
thread-safe once returned by a getter.
The existing API continues to work as before, except in the case where a
key is set/got as both a uint and a uint64 — there will now be a
collision (and a GVariant type checking failure) whereas previously
there was no collision. Nothing in OSTree uses OstreeAsyncProgress this
way though.
The new API can be used to share more complex data via the progress API.

Instead of using G_OPTION_ARG_STRING, use G_OPTION_ARG_FILENAME, which
handles filename encoding conversion differently from the locale
conversion which G_OPTION_ARG_STRING. This will fix argument handling on
systems where the filename encoding is not the same as the locale
encoding (which is fairly unlikely since most systems use UTF-8).

Add a ostree_raw_file_to_archive_z2_stream_with_options() variant of
ostree_raw_file_to_archive_z2_stream(), to allow a compression-level
option to be passed in and passed through to zlib.
This is useful when building archive-z2 files on the fly for
transmission over a non-bandwidth-limited channel, such as a local
network. In this case, CPU time is more valuable than bandwidth, so we
want a low compression level.

If --enable-man=maybe (the default), and xsltproc is not available, the
configuration code would check for it, correctly set enable_man=no, then
incorrectly overwrite that with enable_man=yes, which would result in
later trying to execute $(XSLTPROC) when it’s empty.

Clarify the documentation for functions like
ostree_repo_get_remote_boolean_option(), stating what out_value will be
set to on error.
