When we switched to a file object and not just a simple string, we missed an update along the way here in target-target conflicts. This patch looks large, but it really comes down to one errant (char *) cast before that has been reworked to explicitly point to the alpm_file_t object. The rest is simply code cleanup.

Should we take this opportunity to rework the file conflict struct type to be well typed instead of using strings everywhere?

struct new_fileconflict_t {        alpm_fileconflict_t *type;        alpm_file_t *file; (frontend would be responsible for root path prepend)        alpm_pkg_t *target;        alpm_pkg_t *ctarget; };

could change package1 and package2 in _alpm_conflict_t also to be actual packages as well instead of strings. Thoughts? On second thought- fileconflict might make sense to use package objects in, but conflict_t looks like it can sometimes be depend-style strings...ugh. We only seem to do that in a few places though...
