This moves most of the parsing work out of the sorting path. The explode
and splitfile functions now call input_new and append input_t structs
to the list of sort candidates instead of raw strings. This lets us
make smarter and easier decisions in the sorting callbacks, which are
now also split into the version and file comparison methods for clarity.
This fixes two bugs:
1) Incorrect ordering with filenames containing epoch in the pkgver
2) Incorrect ordering with package names which are substrings of
each other (e.g. "systemd" and "systemd-sysvcompat").
Performance of the --files mode degrades slightly as a result of this
change, but not unreasonably. Sorting with small inputs (5-10) doubles
in runtime, but larger inputs (4000+) only increase by 20%.

Forcing vim users to view files with a tabstop of 2 seems really
unnecessary when noet is set. I find it much easier to read code with
ts=4 and I dislike having to override the modeline by hand.
Command run:
find . -type f -exec sed -i '/vim.* noet/s# ts=2 sw=2##' {} +

Self-executing tests were not being run through the tap log driver.
This caused `make check` to ignore discrepancies between the expected
number of tests and the actual number of tests.
Also, fix some uncommented output from test scripts that could confuse
TAP parsers.

Our test scripts currently require that the first argument be the
library or binary to be tested. This makes integrating them with
automake which doesn't have a mechanism for passing specific arguments
to individual tests. Instead, provide a default built from paths in the
environment which can be provided to all test scripts by automake.

Teach pacsort to understand package filenames and optionally strip away
some of the context. alpm_pkg_vercmp() intentionally only understands
pure versions, so strings such as '18.0-2-x86_64' and '18.0.1-1-x86_64'
will be compared wrongly.
Partially addresses FS#33455.

Make the output into a single block and add separators at the end
so that they do not merge into each other.

We had this interesting set of facts conundrum, according to vercmp
return values:
2.0a < 2.0
2.0 < 2.0.a
2.0a == 2.0.a
This introduces a code change that ensures '2.0a < 2.0.a' as would be
expected by the first two comparisons. Unfortunately this stays us a bit
further from upstream RPM code, but those are the breaks (in RPM, the
versions involving 'a' do in fact compare the same, but they are both
greater than the bare '2.0').

Note that this is meant to exercise pacsort more than the underlying
version comparsion; that is better left to the standalone vercmptest.sh
test script.

The vercmptest script needs to be invoked as a bash script for this to
be valid; the -p operator is interpreted as an argument to look up by
sh. This goes way back to commit 3bf9448943dc0b, done to solve
http://mailman.archlinux.org/pipermail/pacman-dev/2008-July/007180.html.
Saw this problem running in a virtual machine where sh is not bash, but
in fact dash:
user@debian-powerpc:~/projects/pacman$ ./test/util/vercmptest.sh
src/util/vercmp-p: not found

Adapting from RPM, follow the [epoch:]version[-release] syntax. We can also
borrow some of their parsing code for our purposes (thanks!). Add some new
tests to our vercmp shell script tester for epoch comparisons, and then make
the code work with these newfangled epoch specifiers.

Now that not everything is in 'pactest/', we can separate out the parts a
bit more and leave the pacman/ directory to be just pactest.
