The problem was after merging udev into systemd, udev is now a virtual pkg
and another dependency was requiring it and added systemd (real pkg) to
the list, but later in the sorting phase systemd was added again breaking
the dependency order.
1- We can cache the result of the first xbps_pkgdb_init() when it fails
and avoid the malloc/free/access from it.
2- We cache the uname(2) result into a private var in xbps_handle and
use it in xbps_pkg_arch_match().
This improves performance by ~5% approx and it's close as it was before
introducing the repository index format 1.5.
- xbps_handle::transd -> new member with transaction dictionary.
- xbps_transaction_prepare: returns an int.
- xbps_transaction_commit: doesn't need any arg now.
- xbps_repository_pool_sync: doesn't need any arg now.
- xbps_pkgdb_update: removed xbps_handle * arg.
- xbps_transaction_missingdeps_get: removed, missing_deps array is in
xbps_handle::transd("missing_deps") array object.
Now to find a virtualpkg set by the user in conf file, there is a new
function: xbps_repository_pool_find_virtualpkg(). Use it in some
places to make jpeg -> libjpeg-turbo (and other pkgs that can be
replaced with other virtual pkgs) work correctly even if installed
multiple times.
- A configuration file "xbps-conf.plist" replaces the (un)register target
in xbps-repo(8) and (un)set-prop in xbps-bin(8). For now, you can set
the repositories and prefered virtual packages.
- New package pattern matching code from NetBSD. Supports more ways of
matching patterns in packages.
- Multiple bugs fixed in virtual packages related matching code.

A new function xbps_find_virtual_pkg_in_dict() has been made public
to the API to make this find duplicate packages in the transaction
when updating packages.
