If we begin to create a file list when loading a package, but abort
because of an error to one of our goto labels, the memory used to create
the file list will leak. This is because we use a set of local variables
to hold the data, and thus _alpm_pkg_free() cannot clean up for us.

This is easily triggered via a `pacman -Sc` operation when it attempts

It can happen that the to-be-downloaded file cannot be created in cachedir.
For example, I am an -Sup user, and it is comfortable to set --cachedir to
/mnt/pendrive, which is a FAT filesystem, so files like
capseo-1:0.3-2-i686.pkg.tar.xz cannot be downloaded to there.
Before this patch, pacman didn't give clear output about what happens when
the download code could not create the necessary file. This can be confusing
with -Su. An example output:

Unfortunately, the "could not open file" error message is printed for
every mirror (that can be dozens of lines), which is ugly, but at least

This reverts commit f3fa77bcf1 along with
making other necessary changes to fully back this (mis)feature out until

The quick summary here is this was not implemented correctly; provides
are not fully taken into account in this logic, and making that happen
exposes a lot of other flaws in this code that are covered up later on
in the dependency resolving process by several other pieces of
convoluted and conditional logic.
Tests have been adjusted accordingly. Some test EXISTS conditions have
been removed as we already know the package is installed locally, and we
also are checking the VERSION condition anyway.
With these two related revert commits, we do have some changes in test
pass/fail results:
* upgrade078.py: does not pass, this is due to --recursive getting
removed for -U/-S operations after this commit.
* sync302.py: the version checks have been disabled, so this test
continues to pass but has been scaled back in scope.
* sync303.py: now passes, was failing before.
* sync304.py: still failing, was failing before.

This makes several small adjustments to our exposed method names, and in

doesn't take a database as the first parameter, it should not.

alpm_db_unregister_all -> alpm_unregister_all_syncdbs
alpm_option_get_localdb -> aplpm_get_localdb

Rework the frontend and backend to allow passing a ratio value in for
UseDelta rather than having a hardcoded #define-d 0.7 value always used.
This is useful for those with fast connections, who would likely benefit
from tuning this ratio to lower values; it is also useful for general
testing purposes.
The libalpm API changes for this, but we do support the old config file
format with a no-value 'UseDelta' option; in this case we simply use the
old default of 0.7.
We clamp the ratio values to a sane range between 0.0 and 2.0, allowing

"invalid" in this case simply means files that may or may not be
archives. Discovered via a `pacman -Sc` operation with delta files in
the package cache directory, but can be triggered if any file is passed
to `pacman -Ql` that isn't an archive, for instance, or if the sync
database file is not an archive.
Fix it up so we are more careful about calling archive_read_finish()

teach our archive open function to set the returned archive to NULL if
we aren't going to be returning something valid anyway.

A look at what this does on 64 bit systems since we were using the
unnecessarily large 'unsigned long' type before even though it was 64

$ ~/bin/bloat-o-meter libalpm.so.old lib/libalpm/.libs/libalpm.so
add/remove: 0/0 grow/shrink: 0/4 up/down: 0/-10412 (-10412)
function old new delta
md5_finish 370 356 -14
sha2_finish 547 531 -16
md5_process 3762 2643 -1119
sha2_process 20356 11093 -9263
The code size is nearly halved in the sha2 case (44% smaller code size),
and md5 gets a nice size reduction (27% smaller) as well.
We also move base64 code to <stdint.h> types as well; we can use
'uint32_t' rather than 'unsigned long' for at least two variables in the
decode function. This doesn't net the same size benefit as the hash code
case, but it is more proper.

This patch changes a variety of small things related to our pkghash
implementation with an eye toward performance, especially on native
32-bit systems.
* Use `unsigned int` rather than `size_t` for hash sizes. We already
return ERANGE for any attempted creation of a hash greater than 1
million elements, so unsigned int is more than large enough for our
purposes. Switching to this type allows 32 bit systems to do native
math without helper functions from libgcc.
* _alpm_pkghash_create() now internally adds extra padding for
additional array elements, rather than that being the responsibility of
the caller.
* #define values are moved into static const values in pkghash.c; a new
`stride` value is also extracted (but remains set at 1).
* Division and modulus operators are removed from the normal find and
add paths if possible. We store the upper limit of the number of
elements in the hash so we no longer need to calculate this every
element addition. When doing wraparound position calculations, we only
apply the modulus operator if the value is greater than the number of
buckets.
