There is no need to run any/remaining pre-transaction hooks as soon as a failure
has occured, which will lead to aborting the transaction.
So if an error occured during the first phase (reading directories/parsing
files), or as soon as a hook flagged abort_on_fail does fail, we stop processing
them and return.
(For post-transaction hooks, all hooks are run regardless since there's no
aborting.)

The path of the default system hook directory was created
by concatenating `myhandle->root` (usually "/"), and
SYSHOOKDIR (usually "/usr/share/libalpm/hooks/"), resulting
in "//usr/share/libalpm/hooks/". Fix this by skipping the
initial slash from SYSHOOKDIR.

Signature downloading and DB validation was being based on the most
recent download status for the DB. If a DB successfully downloaded but
a signature did not, db_update would move to the next server. If the
next server tried does not have a more recent copy of the DB, db_update
would not download the DB again and would forget that the DB had
previously been updated. In this case it would skip validation
entirely, leaving an updated DB with the original validation status.

When replacing a file with a directory, any files inside the new

libarchive will not extract a directory over an existing directory
symlink, making it impossible to replace a symlink with a directory
across packages. Adding the ARCHIVE_EXTRACT_UNLINK and
ARCHIVE_EXTRACT_SECURE_SYMLINKS causes libarchive to unlink the existing
symlink and prevents it from extracting any paths that contain
a symlink, which we should not be doing anyway.

When a database and its signature is updated non-atomically on a server,
there is a window where a user may update the database but grab the old
signature. The database is marked as invalid by libalpm, which can be
fixed by forcing a refresh (assuming the server has caught up and the
user realizes what has happened) or with a future update of the repo.
Work around this by forcing a repository refresh whenever a database is
invalid.

While loading each package ensure that the internal version matches the
expected database version to avoid the possibility to circumvent the
version check.
This issue can be used by an attacker to trick the software into
installing an older version. The behavior can be exploited by a
man-in-the-middle attack through specially crafted database tarball
containing a higher version, yet actually delivering an older and
vulnerable version, which was previously shipped.

If a sync database contains a "files" file, the file list will be read.
