Thanks to Allan for inspiring all this work on what was one little TODO item
in the codebase. :)
Change changelog handling so we can now dump a changelog from both installed
packages and package files (fixes FS#7371). We do this by moving all of the
machinery to the backend where it should have been in the first place.
The changelog reading is now done through a open/read/close interface
similar to the fopen/fread/fclose functions (can you guess how it is done?).
It is buffered by the frontend, so programs using the library can read as
much or as little as they want at a time.
Unfortunately, I could not implement a changelog_feof function due to some
shortcomings of libarchive. However, I left the stub code in there,
commented out, in case it becomes possible later or anyone wants to take a
stab at it.

During a pacman operation such as a group install, pacman can ask several
questions such as "local version is up to date. Upgrade anyway?". They are
usually all answered either by yes or by no:
* yes when you want to reinstall all the targets.
* no when you only want to install the missing ones (either because you are
installing a group, or because you are copying a pacman -S line from wiki or
whatever).
So instead of asking this question for each target, it is now now configured
with a flag. Yes will be the default -S behavior, No will be achieved with
the --needed flag.

checkdeps and resolvedeps now take both a remove list and an install list as
arguments, allowing dependencies to be calculated correctly.
This broke the sync990 pactest, but this pactest used dependencies and
provides in an unusual way, so it has been changed.
Dan: the sync990 pactest was just plain wrong. It didn't satisfy the
dependencies correctly, so should never have succeeded.

The alpm_get_upgrades was exactly the same as find_replacements +
_alpm_sync_sysupgrade, except that it automatically made the eventual
replacements, without asking the user : Replace %s with %s/%s? [Y/n]
The replace question, asked in find_replacements. can now be skipped by
using a NULL trans argument, so that we get the same behavior as with
alpm_get_upgrades.
So alpm_db_get_upgrades() can now be replaced by
alpm_sync_sysupgrade(db_local, syncdbs).

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

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

Setting this option will change the download progress to show the amount

Packages and DBs now support using the UNIX epoch (seconds since Jan 1, 1970)
for use in builddate and installdate. This will only affect newly built
packages. Old existing packages with the text format are still supported, but
this is deprecated.
In the case of removal of text time support, this code will fail gracefully,
returning the start of the epoch for broken packages.

In most cases, we want to fully scan a package when we load it, which serves
as a integrity verification check. However, there are times when it is only
desired to read the metadata and nothing else, so allow the caller of pkg_load
to choose the behavior they need.
This pays big dividends in speeding up pacman cache cleaning functionality.
Old (729 packages):
real 1m43.717s

Previously, package names must match a specified scheme or they will cause
pacman add operations to fail. This is not a very intelligent or necessary
way to act, so remove the dependency on the name of the package to be
installed and read all relevant information from the metadata instead.
This does have one causality to be addressed later- pacman cache cleaning
functionality, which has never been phenomenal, just lost most capability.

My two previous hacks related to this part
(8038190c7c4786e1c49494eea1b40cdddcbd5136 and
b15a5194d1a8485a2769560e49e6ff03e1862533) 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 (54008798efcc9646f622f6b052ecd83281d57cda).
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.

I'm currently working on python bindings for alpm written in pyrex. While
working i found that declaring alpm_strerror as
char * alpm_strerror (void)
instead of
char * alpm_strerror (int err)
and then using pm_errno in the implementation instead of err, could make it
more bindings-friendly.
Dan: cleaned up and added void to declaration. Instead of replacing existing
function, add a new function called 'alpm_strerrorlast(void)'.

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,
This removes the silly limitation that a sync DB couldn't be named 'local',
along with structurally separating sync DBs and the local DB in the
filesystem.

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.

This basically moves the code from alpm_release, which was mostly about
unregistering all databases, to a safer alpm_db_unregister_all.
This allows to avoid modifying the dbs_sync list while iterating over it,
and and also prevent alpm_release from looping infinitely when a database
can't be unregistered.

Based on the "depth first search" algorithm, for more infos visit:
http://en.wikipedia.org/wiki/Topological_sorting
The previous algorithm used by sortbydeps was too slow, and to work around
it the number of steps needed to get correct result was reduced greatly.
So it produced wrong results in several cases :
1) smoke001.py
2) http://bugs.archlinux.org/task/7229
