bd98b93a6e makepkg: escape closing bash array paren for awk
The closing parenthesis of bash arrays needs to be escaped in the ending
address of awk expressions in order to play nicely with implementations
of awk other than gawk. This change provides compatibility with gawk,
nawk and mawk.

eb93955477 makepkg: allow pkgname usage in split package functions
Currently, using $pkgname in a split package package_*() function
always returns the first value in the pkgname array rather than the
name of tha package being packaged.  Fix this so $pkgname gives the
expected value.

Fixes FS#22174

735a197fc2 Use name hashes in depends to avoid strcmp calls
Just like we did for package name comparsions, if we add a depend name_hash
field on depend struct initialization, we can use it instead of doing a
string name comparison, saving us a lot of checks in the depcmp code.

34a78d935a Remove need for memory allocation in _alpm_depcmp
Noticed when tweaking testdb, when we run _alpm_depcmp in loops and call it
seven million times, the strdup()/free() combo can add up. Remove the need
for any string duplication by some pointer manipulation and use of strncmp
instead of strcmp. Also kill the function logger and add an escape so we
don't needlessly retrieve the list of provides.

f2dff08600 Overhaul archive fgets function
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.

919bb6c9e0 Used hashed package name in _alpm_pkg_find
This results in huge gains to a lot of our codepaths since this is the most
frequent method of random access to packages in a list. The gains are seen
in both profiling and real life.

    $ pacman -Sii zvbi
    real: 0.41 sec -> 0.32 sec
    strcmp: 16,669,760 calls -> 473,942 calls
    _alpm_pkg_find: 52.73% -> 26.31% of time

    $ pacman -Su (no upgrades found)
    real: 0.40 sec -> 0.50 sec
    strcmp: 19,497,226 calls -> 524,097 calls
    _alpm_pkg_find: 52.36% -> 26.15% of time

There is some minor risk with this patch, but most of it should be avoided
by falling back to strcmp() if we encounter a package with a '0' hash value
(which we should not via any existing code path). We also do a strcmp once
hash values match to ensure against hash collisions. The risk left is that a
package name is modified once it was originally set, but the hash value is
left alone. That would probably result in a lot of other problems anyway.

21833d90e2 Merge desc and depends files in local db
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.

209d0643e5 Attempt to stop installation when we encounter problems
This should hopefully address some of the concerns raised in FS#11639 with
regards to continuing after filling the disk up.

Add some more checks and passing of error conditions between our functions.
When a libarchive warning is encountered, check if it is due to lack of disk
space and if so upgrade it to an error condition.  A review of other
libarchive warnings suggests that these are less critical and can remain as
informative warning messages at this stage.

Note the presence of errors after extraction of an entire package is complete.
If so, we abort the transaction to be on the safe side and keep damage to a
minimum.

e527699ddd Add functions to calculate approximate disk usage by packages
Two helper function are added to calculate the disk usage from packages
that are either currently installed on the system or from a package
archive.

Some minor approximations have been made:

1. Size for directories is not considered when removing a package from the
   filesystem to avoid multiple counting across packages. Also, these are
   reported to take zero size while installing.

2. Symlinks are reported to contribute zero size towards removal as
   libarchive reports them to have zero size for install.

3. Package data files (.PKGINFO, .INSTALL, .CHANGELOG) are counted towards
   usage on dbpath on install, but their size is not counted on package
   removal.

4. No handling of extra size needed for .pacsave/.pacnew files.
