> 
>     Add SyncFirst option.
>     
>     This patch offers a way to fix FS#9228.
>     By putting "SyncFirst = pacman" in pacman.conf, the version check will
>     happen before the transaction really starts, and before any replacements
> is
>     made.
>     Otherwise, no version check is done.
>     
>     The sync301 pactest was updated to use this SyncFirst option.
>     
>     Example session with SyncFirst = pacman, and a newer pacman version
>     available :
>     $ pacman -Su (or pacman -S <any targets>)
>     :: the following packages should be upgraded first :
>         pacman
>     :: Do you want to cancel the current operation
>     :: and upgrade these packages now? [Y/n]
>     
>     resolving dependencies...
>     looking for inter-conflicts...
>     
>     Targets: pacman-x.y.z-t

>     Total Download Size:    x.xx MB
>     Total Installed Size:   x.xx MB

>     As Nagy previously noted, doing this check on any -S operations might
> look
>     intrusive, but it can be required.
>     For example, the case where you want to install a package with versioned
>     provisions, using a pacman version which didn't support that feature yet
>     (and there is already a newer pacman in sync db supporting it).

>     Cleanup usages of alpm_list_find and alpm_list_remove.
>     
>     * remove obsolete and unused *_cmp helper functions like deppkg_cmp and
>     _alpm_grp_cmp
>     
>     * new alpm_list_remove_str function, used 6 times in handle.c
>     
>     * remove _alpm_prov_cmp / _alpm_db_whatprovides and replace them by
>     a more general alpm_find_pkg_satisfiers with a cleaner implementation.
>     before: alpm_db_whatprovides(db, targ)
>     after: alpm_find_pkg_satisfiers(alpm_db_getpkgcache(db), targ)

Warning: pkg literal also satisfies pkg. But in most cases we called 
what_provides if we didn't find a literal.

>     before : alpm_list_find(_alpm_db_get_pkgcache(db), dep, satisfycmp)
>     after : _alpm_find_dep_satisfiers(_alpm_db_get_pkgcache(db), dep)

Warning: possible slowdown, the old way just stopped after a satisfier (which 
is ideal in checkdeps), now we scan the whole db.

Imho this is ugly. First we find it, then we again find it via list_remove.
