kill -l SIGHUP (or any other signal-name prefixed with "SIG")
would cause free() to be called with a bad pointer instead of
a pointer to what was allocated. Fix this and add test-case.
FreeBSD doesn't have SIGPWR so makes no sense in warning and assuming
its 29.
Picked from master, but the file has moved from proc/sig.c to
library/signals.c

The first part of fixing skill/snice to use the library instead
of directly readdir()ing /proc which is what it does now.
Remove the kill code from the skill/snice code and put common
elements into lib/signals.c Not 100% sure that is the right
destination instead of a new lib file, but ok for now.
kill shares some parsing logic with skill/snice but mainly
around signal specifications. The "do it" code is very different.

Procps library previously held functions that were about either
listing or finding signal names. These are not really the right
location for a library about reading procfs.
This patch handles signal related functions in two ways:
For functions purely found in skill, these have been moved back
into this binary as they are used nowhere else.
For functions used across the binaries, these have been moved
into include/signals.h and lib/signals.c. Besides formatting,
these functions are largely the same.
To assist the skill functions, two functions to access the
signal map array have been added to lib/signals.c
