Clean up libalpm/add.c and revise file extraction code
This is a full refactoring of _alpm_add_commit into multiple functions and a better layout for later. Some highlights: * No regressions in pactest performance. * Much cleaner layout. add_commit is split into four functions: upgrade_remove, extract_single_file, commit_single_pkg, _alpm_add_commit * No more super-functions, the heaviest (extract_single_file) is finally under 400 lines, with much improved commenting as well. * Incorporation of Andrew Fyfe's ideas for fixing FS #7484. Try to handle all possible cases of extraction combinations with files, symlinks, dirs, and non-existant entries on the filesystem. This should make our dealings with libarchive fall more into our control. Signed-off-by: Dan McGee <dan@archlinux.org>
