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.

In 5acfa65f when adding a new variable (hit_mtree), the initialization of a
variable (config) was dropped, which could lead to loading invalid package
files, i.e. files that aren't archive (no metadata loaded) would return a new
alpm_pkg_t with everything set to 0/NULL.
Depending on the operation/use of the package, this could lead to segfault.

Problems due to concurrent running instances of pacman can be difficult
to diagnose. Log a warning to make it more obvious that that's what
happened, that it's a bad idea, and hopefully encourage people who do
things like removing the lock file to run pacman from an install script
to at least be courteous enough to put it back when they're done.

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.
