While that old master branch library may utilize those
memory allocation functions found in the alloc module,
it was inappropriate for this newlib branch to subject
callers to a stderr message followed by an early exit.
Of course, the old libprocps offered a message handler
override provision (xalloc_err_handler) but that, too,
would seem to be inappropriate for our modern library.
[ remember the battles fought with that damn libnuma ]
So, this commit will tweak those old inherited sources
setting the stage for standardized return values/errno
settings in connection with a memory allocation error.
------------------------------------------------------
Along the way, we'll address the following miscellany:
. Completely eliminate usage of anything from alloc.h.
This, of course, entails our own error checking of the
alternative allocation calls from stdlib.h & string.h.
. Eliminate use of the strdup function where possible,
as with 'procps_uptime' and 'procps_loadavg' routines.
. Whack some obsolete code (getslabinfo) in sysinfo.c.
