In the case of -Rs operation, first pulling the dependencies with
recursedeps before calling checkdeps takes care of the dependency chain of
remove052 pactest.
In the case of -Rcs, we can keep the old behavior because we have no problem
there (any dependency returned by checkdeps will be added to the remove list
because of -Rc) and we have to run recursedeps on the final remove list
anyway to catch all orphans.

_alpm_pkgname_pkg_cmp(pkgname, pkg) returns true iff pkg's name is pkgname.
This is useful if you want to remove a package from pmpkg_t* list, and you
want to search for package name.

With --unneeded option 'pacman -R' doesn't stop in case of dependency error;
it removes the needed-dependency targets from the target-list instead. See
also: http://archlinux.org/pipermail/pacman-dev/2007-October/009653.html .
The patch also adds a new causingpkg field to pmdepmissing_t which indicates
the to-be-removed package which would cause a dependency break. This is
needed, because miss->depend.name may be a provision. miss->causingpkg will
be useful in -R dependency error messages too.
[Xavier: renamed inducer to causingpkg, removed the _alpm_pkgname_pkg_cmp
helper function as requested by Aaron. This might be added by a further

This also affects all structures with static strings, such as depmiss,

Currently our pactest pass/fail rate is identical before and after this

checkdeps and resolvedeps now take both a remove list and an install list as
arguments, allowing dependencies to be calculated correctly.
This broke the sync990 pactest, but this pactest used dependencies and

Dan: the sync990 pactest was just plain wrong. It didn't satisfy the
dependencies correctly, so should never have succeeded.

* The frontend calls alpm_trans_prepare(&data), and in case of errors,
receive the missing dependencies / conflicts / etc in the data pointer.
It apparently needs to free this structure totally with :
alpm_list_free_inner(data, free)
alpm_list_free(data)
So I added alpm_list_free_inner(data, free) in
pacman/{sync.c,remove.c,add,c}
* in _alpm_sync_prepare, the deps and asked lists were not freed in case
of errors (unresolvable conflicts).
Besides the code for handling this case was duplicated.
* in _alpm_remove_commit, free was used instead of alpm_list_free for
newfiles.
* newline fix in pacman/sync.c

The names related to conflicts are misleading :
For dependencies conflicts, the type is pmdepmissing,
and the function names contain just "conflict".
For file conflicts, the type is pmconflict,
and some functions contained just "conflict", some others "fileconflict".
So this is the first step for improving the situation.
Original idea/patch from Nagy, but the patch already didn't apply anymore,
so I did it again.
The main difference is that I kept the conflictype, with the following renaming :
pmconflicttype_t -> pmfileconflicttype_t
PM_CONFLICT_TYPE_TARGET -> PM_FILECONFLICT_TARGET
PM_CONFLICT_TYPE_FILE -> PM_FILECONFLICT_FILESYSTEM

It's time to define that alpm_list_add(list, foo) adds 'foo' to the end of
'list' and returns with 'list', because:
1. list is a list, not a set.
2. sortbydeps _needs_ an alpm_list_add definition to work properly.
As a first step, I used this definition in recursedeps.

As seen with the recent upgrade of pacman and the removal of the
pacman.d/current mirrorlist, files that were formerly in the backup array
get deleted upon their removal, which could be dangerous. Instead, we should
use the combined backup array of the old and new package. This fix should
address this issue in a relatively straightforward way.
In addition, old files should be moved to pacsave locations as expected.

My two previous hacks related to this part
(8038190c7c and
b15a5194d1) were caused by the lack of
understanding of a feature introduced a while ago:
Better control over CTRL-C interruptions -- do not leave the DB in an
inconsistent state (54008798ef).
Now I have been looking at this commit, and the added feature is indeed
interesting. The main problem I had with it is that it does a rather
unusual use of alpm_trans_release, which caused a few problems that I tried
to fix in a weird way. I think these problems were caused by the fact that
there weren't any difference between "interrupt transaction" and "release a
transaction which failed" actions from the alpm_trans_release POV. So I
decided to add a new function instead, alpm_trans_interrupt, which is
called on Ctrl+C, and which only sets trans->state to STATE_INTERRUPTED so
that remove_commit and add_commit can exit cleanly at a safe moment. This
allowed me to revert my two previous hacks as well.
Also ensure we handle SIGINT correctly in all cases- if a transaction is
not ongoing, then we can free the transaction and exit quickly.
