The old function was written in a time before we relied on it for nearly
every operation. Since then, we have switched to the archive backend and now
fast parsing is a big deal.
The former function made a per-character call to the libarchive
archive_read_data() function, which resulted in some 21 million calls in a
typical "load all sync dbs" operation. If we instead do some buffering of
our own and read the blocks directly, and then find our newlines from there,
we can cut out the multiple layers of overhead and go from archive to parsed
data much quicker.
Both users of the former function are switched over to the new signature,
made easier by the macros now in place in the sync backend parsing code.
Performance: for a `pacman -Su` (no upgrades available),
_alpm_archive_fgets() goes from being 29% of the total time to 12% The time
spent on the libarchive function being called dropped from 24% to 6%.
This pushes _alpm_pkg_find back to the title of slowest low-level function.

The splitname function is a general utility function and so is better
suited to util.h. Rename it to _alpm_splitname to indicate it is an
internal libalpm function as was the case prior to splitting local and

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.

This crude function allows reading from an archive on a line-by-line basis
similar to the familiar fgets() call on a FILE stream. This is the first

test_delta_md5sum and test_pkg_md5sum were simple wrappers to test_md5sum,
and only used once, so not very useful. I removed them.
Also, test_md5sum and alpm_pkg_checkmd5sum functions were a bit duplicated,
so I refactored them with a new _alpm_test_md5sum function in libalpm/util.c

This also affects all structures with static strings, such as depmiss,
conflict, etc. This should help a lot with memory usage, and hopefully make
things a bit more "idiot proof".
Currently our pactest pass/fail rate is identical before and after this
patch. This is not to say it is a perfect patch- I have yet to pull valgrind
out. However, this should be quite safe to use in all situations from here
on out, and we can start plugging the memleaks.

Legacy code is hitting the trash here. Remove unnecessary _alpm_time2string
time storage abstraction in favor of just writing the time_t value to the

The only drawback is that everyone's sync DBs will have to be updated at
least once so that the lastupdate values are stored right. :)

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.

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.

Change the default visibility of libalpm functions to internal instead of
hidden- this allows for slightly better optimization because it tells GCC
that the function can never be called outside of the current module (see
http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html).
Also added some attributes to the pacman print functions so that they check
the format strings being passed to them.

This change allows us to use all autoconf specified paths, most notably
$(localstatedir). It is quite a change and touches a lot of files, as
all references to the DB and cache were done with the ROOTDIR as a prefix.
* add --lock command-line option to pacman to specify the location of the
lockfile (this can now be specified at configure time by setting the
$localstatedir path).
* Rip quite a few settings out of configure.ac as they are now picked by
setting the paths during configure or make.
* Fix bug with /tmp fallback for sync downloads not working correctly
(related to root location, now the system tmp dir is used).
* Simplified the parameters to some libalpm functions, and added get/set
for the new lockfile option.
* Renamed several of the DEFS to names without the PM_ prefix.

Small change (addition of a 'strreplace' function) which replaces
any $repo tokens found in a server line with the name of the repo

While this is more simplistic than suggestions on flyspray, it works

* Moved entirely to alpm_pkg_get_* accessors, to read data on demand
* Mostly removed the INFRQ_ parameters from outside the be_files backend (making
the backend more extensible in the long run)
* packages created from _alpm_db_scan now have the db and origin set (making
accessors actually work for these packages)
* removed _alpm_db_ensure_pkgcache
* totally revamped the _alpm_checkconflicts function, making it cleaner and
easier to read (and thus fix in the long run) - maintainable code ftw
NOTE: feel free to rename the functions... I couldn't think of anything better
* removed an extra loop in sync.c:find_replacements - no sense in looping over
an entire DB while strcmp'ing the name, when we have get_pkgfromcache
Other:
* package struct "license" -> "licenses"
* Created _alpm_sync_find (duplicate code in some places, find_pkginsync
* Minor const correctness changes along the way
* fixed a couple extra '/' pathing issues (non-issues really)
* removed a duplicate pkg_cmp function
unbelievable amount of strcmp() calls (25 million) due to the list searching.
This has been reimplemented with a set-intersection scheme, due to the fact
that file lists are always ordered. - NEEDS TESTING
* Minor clean up, "globalized" the str_cmp helper to match the alpm comparison
signature, so we can use it elsewhere.
optimizations in order to make the code much more readable and
type-checkable. Every enum in the library now has it's own type that
should be used instead of the generic 'unsigned char'. In addition,
several #define statements dealing with constants were converted to
enums.
