Commit 8240da6cb3 broke some alpm hierarchy
and introduced a new memleak (trans->packages was never freed in case of add
transaction, even if the transaction wasn't committed), so it is reverted
now.
We follow a different approach to reduce memory usage:
_alpm_db_add_pkgincache doesn't duplicate the whole package before adding
it to the cache, only the package name and version (INFRQ_BASE).
This method needs very small extra memory (compared to the reverted method),
and after transaction commit we use less memory than before (since the
big 'files' fields are not copied to cache), this is useful in GUIs.
Note: The old add_pkgincache was a bit broken, since pkg->origin wasn't
filled in correctly.

Now '-S provision' handling is done in the back-end.
In case of multiple providers, the first one is selected (behavior change:
deleted provision002.py). The old processing order was: literal, group,
provision; the new one: literal, provision, group. This is more rational,
but "pacman -S group" will be slower now. "pacman -S repo/provision" also
works. Provision was generalized to dependencies, so you can resolve deps by
hand: "pacman -S 'bash>2.0'" or "pacman -S 'core/bash>2.0'" etc. This can be
useful in makepkg dependency resolving. The changes were documented in
pacman manual.
alpm_find_pkg_satisfiers and _alpm_find_dep_satisfiers functions were
removed, since they are no longer needed.
I added some verbosity to "select provider instead of literal" and
"fallback to group".

I divided resolvedeps into 2 functions. The new _alpm_resolvedep function
will resolve one dependency, for example the 'foo>=1.0-1' dependency. It
can be useful in sync_addtarget refactoring.
The resolvedeps parameters were changed, to be coherent with recursedeps:
* the target-list is an alpm_list* instead of alpm_list**. This is OK,
because alpm_list_add == alpm_list_add_last
* syncpkg param was removed. list contains the to-be-installed packages,
resolvedeps will add the required dependencies into this list
* trans param was removed, it was used in QUESTION() only, which can be used
on the main (handle->trans) transaction only (because the front-end cannot
access our pseudo-transactions at all!).
The patch fixes some wrong dynamic pmdepmissing_t usage.
I did a behavior change (and sync1003.py was modified accordingly), which
needs some explanation: The old resolvedeps didn't elect packages from
'remove' list. I've dropped this because I don't want that 2nd excluding
list param. In fact, in real life, we ~never need this rule. Resolvedeps is
called before checkconflicts, so only -Su's %REPLACES% packages are sitting
in 'remove' list. This means, that we have the replacement packages in our
target list. Usually "foo replaces bar" means, that bar isn't in our repos
any more, so resolvedeps *cannot* elect it; but usually it won't try it at
all, because foo is in the target list, and it is expected to satisfy
'bar>=1.0-1'-like dependencies too. Since checkdeps and checkconflicts is
done after resolvedeps, this cannot cause any harm.

Some previous commits apparently broke the get_filename function for package
loaded with pkg_load (on a -Qip operation) because this field was no longer
filled. Now pkg_load fills it.
But the -Qip operation needs to be run like this : -Qip <filename>, so the
filename is already known. There is no need to display it again.
Besides, on a normal -Qi operation, the filename is not displayed either
because this information is not stored in the local database.

Errors like the following one happen regularly (for unknown reasons...) :
error: could not open file /var/lib/pacman/local//glibc-2.7-9/depends: No
such file or directory
Anyway, every time an user reported an error like that, it always seemed
like he thought the error was caused by the double /, which is obviously
wrong.
Since db->path always include a trailing /, there is no need to add one when
concatenating paths in be_files.c or add.c.
Additionally, some static strings were switched to dynamic.
And the computation of the "dbpath"/"pkgname"-"pkgversion" was refactored
in db_read, db_write and db_remove with a get_pkgpath static function.

Add a new totaldlcb callback function to libalpm and make pacman utilize it
when the TotalDownload option is enabled. This callback function is pretty
simple- it is meant to be called once at the beginning of a "list download"
action, and once at the end (with value 0 to indicate the list has been
finished). The frontend is responsible for keeping track of adding
individual file download amounts to the total xfered amount in order to
display some sort of overall progress.

We have been using unsigned long as a file size type for a while, which
works but isn't quite correct and could easily break. Worse was probably our
use of int in the download callback functions, which could be restrictive
for packages > 2GB in size.
Switch all file size variables to use off_t, which is the preferred type for
file sizes. Note that at least on Linux, all applications compiled against
libalpm must now be sure to use large file support, where _FILE_OFFSET_BITS
is defined to be 64 or there will be some weird issues that crop up.

repo-add and db_read both assume that REPLACES and FORCE fields are in the

Note that db_write is currently only used on the local database. And the
only purpose of replaces and force in local database is for information
purpose (available on -Qi operations). So this is not a big problem.

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.

Commit 0460038447 caused a regression when
rereading the pkgcache after updating the on-disk databases. A rewinddir
call was errantly removed.
Instead of replacing the call to rewindir, clean up this whole mess.
db_scan is used only once and with target == NULL so there was actually half
the code of db_scan which was unused. This is gone now and replaced by a
single new db_populate function.
Dan: add_sorted ended up being 3x slower than one msort at the end, so I
changed back to that. I also made one pointer variable const and merged this
whole patch with my original fix for the rewinddir issue.
