The signedness of char is implementation defined. On systems where
char is unsigned, comparing a variable of type char with -1 is never
true, due to integer promotion rules. To avoid this, introduce a
define for invalid field separators where -1 is cast to char. This will
ensure that the return value check works for both unsigned and signed char.
Fixes one warning [-Wtype-limits] for comparissons with -1 when compiling
with -funsigned-char.

Since it can fail, check the return value.
If it fails, we need to free the memory of the object we wanted
to add to the list.

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.

Unify the formatting of the --help switch for pacman utils, if it exists.
All of the pacman utils will now output help text using the following
format:
util-name (pacman) v<pacman version>
one line description of util's purpose
Usage: util-name [options]
-b, --bar whatever --bar does
-f, --foo whatever --foo does
-h, --help display this help message
The --help switch does not exist for a couple of the utils, so the
help/usage text for those will be displayed when the util is run
with no arguments.

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.

Ensures that config.h is always ordered correctly (first) in the
includes. Also means that new source files get this for free without
having to remember to add it.
We opt for -imacros over -include as its more portable, and the
added constraint by -imacros doesn't bother us for config.h.
This also touches the HACKING file to remove the explicit mention of
config.h as part of the includes.
