After our recent screwup with size_t and ssize_t in the download code, I
found the `-Wsign-conversion` flag to GCC to see if we were doing anything
else boneheaded. I didn't find anything quite as bad, but we did have some
goofups- most of our public unsigned methods would return -1 on error, which
is a bit odd in an unsigned context.

Commit 34e1413d75 attempted to implement lazy loading of package databases.
Although it took care of my main complaint (creating the database directory
if it didn't exist), it didn't allow sync repos to be registered before
alpm_option_set_dbpath() had been called.
With this patch, we no longer compute the individual repository DB paths
until necessary, allowing full lazy loading to work as intended, and
allowing us to drop the extra setlibpath() calls from the frontend. This
allows the changes introduced in a2cd48960 (but later reverted) to be added
back in again.

This fixes FS#14899. When running an -Sp operation without servers
configured for a repository, we would segfault, so add an assert to the
backend method returning the first server preventing a null pointer
dereference.
In addition, add a new error code to libalpm that indicates we have no
servers configured for a repository. This makes -Sy and -S <package>
operations fail gracefully and helpfully when a repo is set up with no
servers, as the default mirrorlist in Arch is provided this way.

We don't need to create the directories when local or sync dbs are
registered. For example, if a sync db does not exist, we cannot even do
"pacman -Q" as an user.
Instead, we can create the local db if needed during the db_prepare
operation, and sync dbs on db_update.
Also remove some more useless abstractions in db_update and switch to a much
more efficient way to remove a sync db : rm -rf.

If a Server specified in pacman.conf had a trailing slash, libalpm ended up
building URLs with double slashes, and this broke libdownload with errors
like the following one :
error: failed retrieving file 'redland-1.0.8-1-i686.pkg.tar.gz'
from 192.168.0.90 : Command okay

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.

Remove what was a pretty weird abstraction in the libalpm backend. Instead
of parsing server URLs as we get them (of which we don't usually use more

Change the 'provname provver' format to 'provname=provver'.
In .PKGINFO, the provisions are copied from the PKGBUILD without quotes. So

See FS#9171.
Dan: Unfortunately we have to change our original specification for
versioned provisions with this patch, but it ends up being the simpler and
cleaner solution in the long run, and if there is any time to change it the
time is now before many packages have been built. Keeping the ' ' based
format would have required us to do special parsing in repo-add, as well as
being susceptible to users not using quotes in their provides array.
Hopefully this will resolve the issues we had with our initial plan. Sorry

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.

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.

Introduce two new methods into the API - alpm_db_register_sync and
alpm_db_register_local, which replace the functionality of
alpm_db_register. db_register_local always returns the local DB, and
db_register_sync will always try to register a sync DB. This conceptually
separates the local DB from sync DBs in the code. Also updated the pacman
frontend to use the new functions. In addition, this changes the location
of all sync DBs in the filesystem from $DBPATH/$REPO to $DBPATH/sync/$REPO,
