This effectively checks that all pkgs in a transaction to be installed
or updated, have not unmatched shared libraries, which might happen with
pkgs that had major soname bumps.
This implementation slow downs xbps_transaction_prepare() 2x, due to
the use of xbps_pkgdb_get_pkg_metadata(). A new pkgdb format is required
that adds the pkg shlib-provides objects to pkgdb, avoiding the need
to use xbps_pkgdb_get_pkg_metadata().
This is magnituds faster than before; some results:

- xbps_binpkg_pkgver() returns a heap allocated string with the pkgver component.
- xbps_binpkg_arch() returns a heap allocated string with the architecture component.
A basename, full path or relative path is supported, i.e:
/path/to/foo-1.0_1.x86_64.xbps
../../foo/blah-0.1_1.x86_64.xbps
baz-0.1_1.x86_64.xbps
- xbps_repo_open() accepts a third argument (bool) to acquire a POSIX file
lock on the repository archive.
- xbps_repo_close() accepts a second argument (bool) to release a POSIX file
lock on the repository archive.
This avoids the issue of multiple xbps-rindex(8) processes being blocked
even for different repositories on the same architecture, resulting in
unnecessary contention.
Rather than collecting dependencies for a pkg that has been added to the
transaction dictionary, do this for all pkgs in transaction once all
packages are already there.
The reason is that even if the pkg was not configured, it should still be accepted
as installed. If installing packages via XBPS_TARGET_ARCH, pkgs are never configured,
so this must be taken into account.
Will be cherry-picked to 0.37 meanwhile.
