Fixes FS#23090, a rather serious problem where the user was completely
unable to read the local database. Even if entry->d_type is available,
the given filesystem providing it may not fill the contents, in which
case we should fall back to a stat() as we did before. In this case, the
filesystem was XFS but there may be others.

Ensure we have a local DB version that is up to par with what we expect
before we go down any road that might modify it. This should prevent
stupid mistakes with the 3.5.X upgrade and people not running
pacman-db-upgrade after the transaction as they will need to.

* Use stat() and not lstat(); we don't care for the size of the symlink if
it is one, we want the size of the reference file.
* FS#22896, fix local database estimation on platforms that don't abide by
the nlink assumption for number of children.
* Fix a missing newline on an error message.

In sync_db_populate() and local_db_populate(), a NULL db->pkgcache is not
caught, allowing the functions to continue instead of exiting.
A later alpm_list_msort() call which uses alpm_list_nth() will thus traverse
invalid pointers in a non-existent db->pkgcache->list.
pm_errno is set to PM_ERR_MEMORY as _alpm_pkghash_create() will only return
NULL when we run out of memory / exceed max hash table size. The local/sync
db_populate() functions are also exited.

When reading the "desc" file in _alpm_local_db_read(), some
strings are trimmed and checked for length > 0 before their
use/duplication subsequently. They are then trimmed again
when there is no need to.
The following code snippet should illustrate it clearly:
while(fgets(line, sizeof(line), fp) &&
strlen(_alpm_strtrim(line))) {
char *linedup;
STRDUP(linedup, _alpm_strtrim(line), goto error);
info->groups = alpm_list_add(info->groups, linedup);
}
This patch removes the redundant _alpm_strtrim() calls in
_alpm_local_db_read() such as the one inside the STRDUP shown
above.

Read the package information for sync/local databases into a pmpkghash_t
structure.
Provide a alpm_db_get_pkgcache_list() method that returns the list from
the hash object. Most usages of alpm_db_get_pkgcache are converted to
this at this stage for ease of implementation. Review whether these are
better accessing the hash table directly at a later stage.

This works for both local and sync databases in slightly different ways. For
the local database, we can use the directory hard link count on the local/
folder. For sync databases, we use the archive size coupled with some
computed average per-package sizes to determine an estimate.
This is currently a dead assignment once calculated, but could be used to
set the initial size of a hash table.

Noted in FS#22697. When I factored out _alpm_parsedate() into a common

failure when NLS is disabled and this header isn't automatically included
everywhere.

Perform the cheap struct and string setup of the local DB at handle
initialization time to match the teardown we do when releasing the handle.
If the local DB is not needed, all real initialization is done lazily after
DB paths and other things have been configured anyway.

Instead, go the same route we have always taken with version-release in
libalpm and treat it all as one piece of information. Makepkg is the only
script that knows about epoch as a distinct value; from there on out we will
parse out the components as necessary.
This makes the code a lot simpler as far as epoch handling goes. The
downside here is that we are tossing some compatibility to the wind;
packages using force will have to be rebuilt with an incremented epoch to
keep their special status.

Due to the way we funk around with package data loading, we had a condition
where the filelist got doubled up because it was loaded twice.
Packages are originally loaded with INFRQ_BASE. In an upgrade/sync, the
package is checked for file conflicts next, leaving us in an "INFRQ_BASE |
INFRQ_FILES" state. Later, when committing a single package, we have an
explicit call to _alpm_local_db_read() with INFRQ_ALL as the level. Because
the package's level did not match this, we skipped over our previous "does
the incoming level match where I'm at" shortcut, and continued to load
things again, because of a lack of fine-grained checking for each of DESC,
FILES, and INSTALL.
The end result is we loaded the filelist twice, causing our remove logic to
iterate twice over the installed files, spewing a bunch of "cannot find file
X" messages.
Fix the problem by doing a bit more bitmasking logic throughout the load
method, and also fix the sanity check at the beginning of the function- this
should *only* be used for local packages as opposed to the "not a package"
check that was there before.
A debug log message was added to upgraderemove as well to match the one
already in the normal remove codepath.

There is a lot of swtiching between size_t and int for alpm_list sizes
in the codebase. Start converting these to all be size_t by adjusting
the return type of alpm_list_count and fixing all additional warnings
given by -Wconversion that are generated by this change.
Dan: a few more small changes to ensure things compile, adjusting some
printf format string characters to accommodate the larger size on x86_64.

All functions that are limited to the local translation unit are
declared static. This exposed that the _pkg_get_deltas declaration
in be_local.c was being satified by the function in packages.c which
when declared static caused linker failures.

Whenever depends is needed from the local db, so is desc. The only
disadvantage to merging them is the additional time taken to read the
depends entries when they are not needed. As depends is in general
relatively small, the additional time taken to read it in will be
negligable. Also, merging these files will speed up local database
access due to less file seeks.

Signed-off-by: Allan McRae <allan@archlinux.org>
The file be_files.c is "split" to be_local.c and be_sync.c in order
to achieve separate handling of sync and local databases.
Some basic clean-up of functions that are only of use for local or
sync databases has been performed and some rough function renaming
in duplicated code has been performed to prevent compilation errors.
However, most of the clean-up and final separation of sync and local
db handling occurs in following patches.
