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)

* remove satisfycmp and replace alpm_list_find + satisfycmp usage by
_alpm_find_dep_satisfiers.
before : alpm_list_find(_alpm_db_get_pkgcache(db), dep, satisfycmp)
after : _alpm_find_dep_satisfiers(_alpm_db_get_pkgcache(db), dep)

* remove _alpm_pkgname_pkg_cmp, which was used with alpm_list_remove, and
use _alpm_pkg_find + alpm_list_remove with _alpm_pkg_cmp instead.

This commit actually get rids of all complicated and asymmetric _cmp
functions. I first thought these functions were worth it, be caused it
allowed us to reuse list_find and list_remove. But this was at the detriment
of the clarity and also the ease of use of these functions, dangerous
because of their asymmetricity.
