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

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.

Readd more or less what was there before, although it still needs a lot of

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):

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.

As seen with the recent upgrade of pacman and the removal of the
pacman.d/current mirrorlist, files that were formerly in the backup array
get deleted upon their removal, which could be dangerous. Instead, we should
use the combined backup array of the old and new package. This fix should
address this issue in a relatively straightforward way.
In addition, old files should be moved to pacsave locations as expected.

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.

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

This patch cleans up and fix the _alpm_trans_update_depends function
and ensure that all requiredby fields are filled in case of multiple satisfiers
(previously, the handling of mutliple satisfiers in that function was inconsistent).
This makes a special case handling of requiredby in commit_single_pkg() obsolete,
and so allows cleaning that code as well.
Also fixed upgrade056 pactest because :
1) the requiredby fields were wrong, and this wouldn't happen with the fixed _alpm_trans_update_depends().
2) this is a very unusual case anyway (and handling all corner cases combined to a broken database
seems nearly impossible to achieve).

We were using a void *data element in pmpkg_t before, which is unsafe by its
nature of being untyped. Reimplement data as origin_data being a union that
can hold either a path to a package file or a pointer to a cache database,
and make the other necesary updates in the code to reflect this. See package.h
for details.

This is a full refactoring of _alpm_add_commit into multiple functions and a
better layout for later. Some highlights:
* No regressions in pactest performance.
* Much cleaner layout. add_commit is split into four functions:
upgrade_remove, extract_single_file, commit_single_pkg, _alpm_add_commit
* No more super-functions, the heaviest (extract_single_file) is finally
under 400 lines, with much improved commenting as well.
* Incorporation of Andrew Fyfe's ideas for fixing FS #7484. Try to handle
all possible cases of extraction combinations with files, symlinks, dirs,
and non-existant entries on the filesystem. This should make our dealings
with libarchive fall more into our control.

Adds the ARCHIVE_EXTRACT_NO_OVERWRITE libarchive flags
for extracting files and directories.
This will prevent symlinks for being overwritten by directories.
All other files that need to be extracted should already have
been deleted previously by pacman.
This flag is not used for extracting files in backup array
to /tmp/alpm_XXXX, because this file is created by mkstemp first,
and so needs to be overwritten by the file from the archive.

With libarchive 2.2.3 (previously 1.3.1), archive_read_extract now returns ARCHIVE_WARN
when a package is extracted as user, because for example, UID=0 or SUID bit can't be set.
This patch makes pacman not treating these warnings as errors anymore,
but simply ignoring them.

For future possibilities, don't extract any files that start with '.'.
This will allow us to add features such as the ChangeLog viewing without
having to wait to include these files in packages, because older versions
of pacman will be forward compatable with 'hidden' files at the root level
of the package.

This was a bad way to fix a problem upstream. Doing this resulted in
symlink permissions being applied to files installed on the system, leaving
