This is the first step in parsing and handling optdepends. There is no
behavior change introduced in this commit; however, depends that contain
a ": " string will now be parsed as having a description and it will be
stored in the depend structure. Later patches will utilize this new
field as appropriate.
This is heavily based on the work of Benedikt, who did something similar
but introduced a new type for this rather than only a new field to the
existing type.

- use simple pointer arithmetic to skip uninteresting cases

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:
***
$ sudo pacman -S capseo bochs --cachedir /c/TEMP

After the patch, pacman will give more informative error message (and
pm_errno is set properly):
***

error: failed to commit transaction (failed to retrieve some files)
***
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
informative... Without modifying the download logic (for example, by
introducing -2 return value for _alpm_download() to indicate giving up),
this ugliness cannot be eliminated.

This reverts commit f3fa77bcf1 along with
making other necessary changes to fully back this (mis)feature out until
we can do it correctly.
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.
* sync305.py: now passes, was failing before.
* sync306.py: still passes, was passing before.

Set errno to 0 at the start of _alpm_open_archive as it is not set when
archive_read_open_fd fails. This can result in _alpm_pkg_load_internal

Some distributions insist on using bash specific commands in their

This can causes issues if (e.g.) their users what to change sh to

pacman -U <pkg> returns a bogus "could not find or read package" if the
file is on a fuse file system that doesn't allow root access. Debug
output isn't very helpful here either so we should log why the access
check failed.
The other 2 checks already log something when failing so logging a more

This makes several small adjustments to our exposed method names, and in
one case, parameters. The justification here is to make methods less odd
in their naming convention. If a method takes an alpm_db_t argument, the
method should be named 'alpm_db_*', but perhaps more importantly, if it
doesn't take a database as the first parameter, it should not.
Summary of changes:
alpm_db_register_sync -> alpm_register_syncdb
alpm_db_unregister_all -> alpm_unregister_all_syncdbs
alpm_option_get_localdb -> aplpm_get_localdb
alpm_option_get_syncdbs -> aplpm_get_syncdbs
alpm_db_readgroup -> alpm_db_get_group
alpm_db_set_pkgreason -> alpm_pkg_set_reason
All methods keep the same argument list except for alpm_pkg_set_reason;
there we drop the 'handle' argument as it can be retrieved from the
passed in package object.

Don't use trailing commas in enums if people really want to use a strict
C89 compiler, and document why on earth one particular enum uses bitmask
values when it doesn't seem necessary.
With comments, shoot for more consistency. When something is a
one-liner, keep it that way and move the whole /** sequence */ to one
line. When it needs more than one line, ensure we format most of them in
a similar fashion.
Two minor function signature adjustments are made that don't change
anything other than matching the parameter name (name -> filename)
and fitting in with our coding style (type* var -> type *var).

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
ratios above 1.0 for testing purposes.

"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()
only on archives that are valid and have not already been closed, and
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
bits wide:
$ ~/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.
