Refactored inconsistent pointer declarations to better improve consistency
throughout the pacman codebase which will, in turn, increase readability to
the user.
Expected format of a pointer declaration:
`typename *varname`

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%.

Calling a signal handler interrupts some functions, most notably read()
and therefore fgets().
Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>
The read() underlying fgets() can be interrupted by a signal handler
causing fgets() to return NULL. Before we started handling SIGWINCH,
the odds of interrupting a read were low and typically resulted in
termination anyway. Replace all fgets calls with a wrapper that retries
in EINTR.

Paths are constructed directly from package file lists and may contain
trailing slashes, causing lstat to dereference symlinks.
Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>
This makes llstat's signature differ from lstat's, but we never actually
use it on a const string and this saves a large number of strdup's.
This also allows stripping multiple trailing slashes and corrects a bug
where calling llstat on "/" would result in calling lstat on an empty
string.

Refactoring getcols, yet again. We do the following:
1) Introduce a static global in src/pacman/util.c
2) getcols always prefers this cached value, but will derive it from
the COLUMNS environment var, the characteristics of stdout, or a sane
default (in that order).
3) Introduce a SIGWINCH signal handler to reset the cached value,
meaning we only call ioctl when we don't know the value.
On my machine, pacman -Syy goes from ~4300 ioctl calls to 3.
One of the comments for this function is out of sync with the code.
Since the code exhibits the more sane behavior of treating SIGINT and
SIGHUB the same way (by not exiting pacman when there is a commit in
flight) we adjust the comment.
Given this code flow, the if/else statements can be simplified somewhat
as well.

ALPM still adds a warning to the log, but doesn't emit an event about
said warning, instead using a specific event to let the frontend what
happened/how to inform the user.
Note that there are 2 cases for installing a .pacnew file, to not
overwrite user changes and because file is in NoUpgrade. In the later case
the warning was a bit different: it happened before and said "extracting"
instead of "installed." Now both happen after and are phrased the same.

These will be emmitted when download a package file from a repository,
indicating that the download starts, and whether it was successfull or
not.
Note that when multiple servers are available, no event is emmitted when
switching to another server.
(This doesn't apply to alpm_fetch_pkgurl(), but since it is called by
the frontend, it shouldn't have problems knowing when the download
starts and when it ends.)
