Fix some fallout from the delta/download changes

We removed one too many FREELIST() calls when trying to fix some memleaks,
and add a safety/sanity check to ensure filename is set, as packages in old
DBs are likely to not have this field.

get_filename : use the FILENAME db field only.

Reference : FS#9547.

The get_filename function first tries to get the filename field from the
database, and if it doesn't find it, it tries to guess it based on the name,
version and arch.

This field was introduced in 3.0, but there are still many old entries in
the official databases without it. So the databases need to be regenerated
first before this patch can be applied.
There is a second problem with the delta code, which needs the filename for
locally installed packages too, but this field is not present in the local
db. So the delta code needs to be fixed first.

Get rid of the delta patches list

As Nathan noticed, the new informations in the delta struct allows us to
get rid of this list :

So I rewrote apply_deltas for that. The previous apply_deltas also had a
limitation: it assumed that the initial package and the deltas were in the
first cache dir, which is not necessarily the case. That situation is
supported now.

Completely rework delta algorithm

Using the graph structures that Nagy set up for dependency sorting, we now
do a similar process for deltas. Load up all of the deltas into a graph
object on which we can then apply Dijkstra's algorithm, using the new weight
field of graph struct.
We initialize the nodes weight using the base files that we can use in our
filecache (both filename and md5sum must match). The algorithm then picks
the best path among those that can be resolved.

Note that this algorithm has a few advantages over the old one:
1. It is completely file agnostic. These delta chains do not have to consist
of package files- this could be adopted to do delta-fied DBs.
2. It does not use the local_db anymore, or even care if a package or file
is currently installed. Instead, it only looks in the filecache for files
and packages that match delta chain entries.

Rework delta struct and modify code accordingly

Start to move the delta struct away from an assumed package name scheme and
towards something that is package (or even filename) agnostic. This will
allow us much greater flexibility in the usage of deltas (maybe even sync
DBs some day) as well as allowing code outside of delta.h/delta.c to be much
cleaner with less of a need for snprintf() calls.

Refactor the trans init and release code.

The calls to alpm_trans_init and alpm_trans_release (+ error checking) were
duplicated between remove.c, sync.c and upgrade.c
This patch introduces trans_init and trans_release functions in util.c to
have this code just once.

So instead of having to do the same change 3 times for fixing FS#10273, I
just had to do it once (so I did it too )

Kill compute_requiredby usage in can_remove_package()

In the can_remove_package function, we don't need to compute the whole
requiredby list, we just need to find one member of it that doesn't belong
to the targets list.
That way we get a small speedup and remove the only usage of
alpm_pkg_compute_requiredby in the backend, so that it can be tweaked for
frontend usage.
