This patch introduces versioned provisions in "provision 1.0-1" format.
_alpm_db_whatprovides was modified accordingly (added sync500.py),
alpm_depcmp was modified accordingly (add043.py passes now; added add044.py
and add045.py).
Notes:
alpm_db_search now uses the whole versioned %PROVIDES% string in its search.
debug logging was simplified in alpm_depcmp.

dash doesn't pass positional parameters to sourced scripts, causing install
scripts to fail. Instead of sourcing the script, make it executable and
call it directly which allows positional parameters to be passed correctly.

pmdepmissing_t was used for two totally different things :
missing dependencies, and dependency conflicts.
So this patch simply adds a type for dep conflicts,
and convert the code to use it.
This fix the TODO in conflict.c :
/* TODO WTF is a 'depmissing' doing indicating a conflict? */
Additionally, the code in conflict.c now eliminates the duplicated conflicts.
If pkg1 conflicts with pkg2, and pkg2 conflicts with pkg1, only one of them will be stored.
However the conflict handling in sync_prepare (sync.c) is still very asymetrical, and very ugly too.
This should be improved in the future (there is already a pending patch from Nagy that cleans it a lot).

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

Suggested by stonecrest on irc :

We discussed this with stonecrest on IRC :
20:46 stonecrest >> someone brings up a good point.. why aren't repos that aren't in the pacman.conf removed from /var/lib/pacman?
20:46 stonecrest >> i have 118mb and 24 dirs in there, but only 5 repos at present
21:26 stonecrest >> shining: i guess you could prompt the user on deleting every dir in /var/lib/pacman.. since it shouldn't happen that often except for
the first time
21:30 stonecrest >> could be part of pacman -Sc.. what else were you thinking?
I already heard about this before, but it sounded dangerous to me. I didn't even think about a simple prompt.
I also didn't know where this code would fit. And it fits well with -Sc, I borrowed most of the code from sync_cleancache.
Example session :
Cache directory: /var/cache/pacman/pkg/
Do you want to remove non-installed packages from cache? [Y/n] n
Database directory: /var/lib/pacman/
Do you want to remove unused repositories? [Y/n]
Do you want to remove /var/lib/pacman/sync/pacman-git? [Y/n]
Do you want to remove /var/lib/pacman/sync/deltatest? [Y/n]
Database directory cleaned up

resolvedeps will now search for other satisfiers

And check the IgnorePkg handling is done correctly in the other places.
For example, -Qu and -Su will automatically skip the ignored packages (-Su will print a warning),
but -S will install ignored packages anyway, because it was asked explicitly.

The fallback on providers when a target is not found was already made in the backend :

The old alpm_list_find was renamed to alpm_list_find_ptr, and a new
alpm_list_find was introduced, which uses the fn comparison-function

Now both alpm_list_find_ptr (a new ptrcmp helper function was also
added) and alpm_list_find_str are just an alpm_list_find call.

Legacy code is hitting the trash here. Remove unnecessary _alpm_time2string
time storage abstraction in favor of just writing the time_t value to the
disk.
The only drawback is that everyone's sync DBs will have to be updated at
least once so that the lastupdate values are stored right. :)

Because alpm_pkg_get_depends() no longer returns strings as the data, we
need to first convert the returned structures to printable strings before
we can print the list.

So I spent a good 4 hours tracking a bug down tonight due to
alpm_list_copy_data not actually doing what I expected to do. We can't find
the size of an object we don't know the type of, so rewrite it so we pass
in the size explicitly. This was making _alpm_pkg_dup fail and causing all
sorts of other issues.

Holy inefficient batman! For a pacman -Qt operation (when we are using
compute_requiredby and not database entries), splitdep was being called ~1.3
million times on my local database. By splitting when we read the DB, we
drop this number to around 1700 and save a LOT of time in doing so (a 5x
increase in pacman -Qt speed here).
Note that the depends alpm_list_t in the package struct is no longer a
string list, but a list of pmdepent_t objects.

Remove any checks dealing with requiredby from pactest (but not actually
from the pactests themselves). Of course, we should probably find a new way
to check requiredby values of packages since there is no guarantee our code
is working perfectly.

Instead of using the often-busted REQUIREDBY entries in the pacman database,
compute them each time they are required. This should help many things:
1. Simplify the codebase
2. Prevent future database corruption
3. Ensure when we do use requiredby, it is always correct
4. Shrink the pmpkg_t memory overhead

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.
