When one package wants to replace a directory by a file, we check that all
files in that directory were owned by that package.
Additionally pacman can be more verbose when the extraction of the symlink
(or file) fails. The patch to add.c looks more complex than it is, I just
moved and reindented code to handle cases 10 and 11 together.

From now on _alpm_db_find_fileconflicts() works with upgrade and remove
target lists (like checkdeps), which makes it transaction independent
(we still need a trans param because of the progressbar). This is a small
step towards the universal transaction. So we call this function directly
from sync.c before commiting the remove transaction. This is much safer,
but we can get false fileconflict error alarms in some tricky cases
("symlinks puzzle" etc).
The patch on find_fileconflict looks complex, but it is mainly an
"indent-patch", the new code-part can be found after the
/* check remove list ... */ comment, and I modified something around the
"file has changed hand" case (see comment modifications in the code).
Unfortunately sync.c became more ugly, because we have to create 2 parallel
internal transactions: to avoid duplicated work, upgrade transaction is
used to load package data (filelists). This problem will disappear, when
we finally get rid of internal transactions.

This has been around since at least pacman 2.9.8. Frugalware just dumped it
in commit 113ec73bfcfdc, and deleting it here and running pactest shows that
nothing that we have actually tested changes. If someone can pactest the
edge case where this is needed, then show me the money.

If the end of the pB list was reached before the end of pA, we failed to
read any remaining files from the pA list. Add an additional loop to ensure
all entries of pA are added to the return list regardless of whether we have
reached the end of pB.
This new loop also eliminates the now-unnecessary check for a null pB, as we
need to ensure we are excluding directories in the resulting output anyway.

This function has a limited purpose, but might be interesting to do a
sanity check from a frontend (eg testdb).
Also removed the private _alpm_checkconflicts function to avoid confusion.
This function was used only once in libalpm, in sync.c, and was just a
single line anyway. Having to do it manually makes it explicit that we are
looking for two kind of conflicts (targ vs targ and db vs targ).

We have a debug message in the target vs. target file conflict check, and
this is a bit rediculous when it comes to watching output from something
like smoke001.py. Instead, put the output outside this inner loop so we only
see it at most once per target, which is much more reasonable.

The deptest code (pacman -T) used by makepkg was mostly in the frontend.
There were 2 drawbacks:
1) the public splitdep function returns a pmdepend_t struct, but the
_alpm_dep_free function for freeing it is private. So there was a memleak.
2) there is a helper in the backend (satisfycmp in deps.c) which makes this
function much easier.
So this adds a new public alpm_deptest in libalpm/deps.c, which cleans
pacman_deptest in pacman/deptest.c a lot.
Besides, alpm_splitdep was made private, because the frontend no longer
requires it, and _alpm_dep_free is also private.
Finally the deptest001 pactest was extended.

This also affects all structures with static strings, such as depmiss,
conflict, etc. This should help a lot with memory usage, and hopefully make
things a bit more "idiot proof".
Currently our pactest pass/fail rate is identical before and after this
patch. This is not to say it is a perfect patch- I have yet to pull valgrind
out. However, this should be quite safe to use in all situations from here
on out, and we can start plugging the memleaks.

The previous fileconflict check (package vs filesystem) skipped the conflict
when the file on the filesystem was a directory or a symlink to a directory,
no matter what the file in the package was.
Now, the conflict will only be skipped if the file in the package is a
directory (so compatible with a dir or a dir symlink on the filesystem).
So in the case of 8156 (new fileconflict003 pactest for this case), instead
of silently ignoring the extraction of the test symlink, pacman will now
fail because of a file conflict between the test symlink in the pkg2 package
and the test directory on the filesystem.

Thanks to the proactive backup handling, we don't need to add the moving
file to the skip_add list.
The backup handling will make sure nothing gets overwritten.

This adds a pactest for the relocation of a config file between two packages
(case of etc/profile moving from bash to filesystem).
While running this pactest, I found out that chk_filedifference didn't work
correctly with an empty list as second argument. So that's fixed now.

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

This really doesn't give us any regressions in behavior, so it is safe to
do although quite ugly. Tell the conflict checking code to ignore symlinks
to dirs so that they are not seen as conflicts.

Linux lstat follows POSIX standards and dereferences a symlink pointing
to a directory if there is a trailing slash. For purposes of libalpm, we
don't want this so make a lstat wrapper that suppresses this behavior.

These macros take the place of the common 4 or 5 line blocks of code we had
in most places that called malloc or calloc. This should reduce some code
duplication and make memory allocation more standard in libalpm.
Highlights:
* Note that the MALLOC macro actually uses calloc, this is just for safety
so that memory is initialized to 0. This can be easily changed in one
place.
* One malloc call was completely eliminated- it made more sense to do it
on the stack.
* The use of RET_ERR in public functions (mainly the alpm_*_new functions)
was standardized, this makes sense so pm_errno is set.

This allows us to remove the hack in the frontend where we added a newline

A bunch of changes related to my first "real" install of pacman-git into
/usr/local and trying to use it.
* Shift some uses of free -> FREE in libalpm.
* Move stat and sanity checks of config paths into libalpm from the
config and argument parsing in pacman.c.
* Fix issue where dbpath still was not defined early enough due to its
requirement for being used in alpm_db_register. This should be rewritten
so it doesn't have this dependency, but this will work for now.

A side effect of the previous commit ( ea9a756eeaca7398c0860b55f8abe2932ad195bd )
is that it's now possible to use versioned conflicts.

The three chk_ functions overlap for packages both in targets and in the
database. This caused the same conflict to be found in both direction
(A conflicts with B, and B conflicts with A).
This patch avoids this duplication. which shouldn't be needed, but other
changes might be required for that to work correctly.
This also has the unexpected side effect to hide the failure of sync022
pactest, for FS #7415. That's maybe not a good thing though..
Note from Dan: sync022 does succeed, but a sync023 pactest added to check
regressions also seems to pass. This may be a valid fix to this 'problem'
sync022 was meant to find.

* Moved entirely to alpm_pkg_get_* accessors, to read data on demand
* Mostly removed the INFRQ_ parameters from outside the be_files backend (making
the backend more extensible in the long run)
* packages created from _alpm_db_scan now have the db and origin set (making
accessors actually work for these packages)
* removed _alpm_db_ensure_pkgcache
* totally revamped the _alpm_checkconflicts function, making it cleaner and
easier to read (and thus fix in the long run) - maintainable code ftw
NOTE: feel free to rename the functions... I couldn't think of anything better
* removed an extra loop in sync.c:find_replacements - no sense in looping over
an entire DB while strcmp'ing the name, when we have get_pkgfromcache

* package struct "license" -> "licenses"
* Created _alpm_sync_find (duplicate code in some places, find_pkginsync
* Minor const correctness changes along the way
* fixed a couple extra '/' pathing issues (non-issues really)
* removed a duplicate pkg_cmp function

* Fixed conflict checking. I had mistakenly assumed that the transaction
packages were of type 'pmsyncpkg_t', but that is not the case. Reverted back
