#12992: pari should avoid usage of mp_set_memory_functions

--------------------------+-------------------------------------------------
I reported the issue to upstream and proposed a patch, for details, see
http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1317
I suggested a patch to not call mp_set_memory_functions if it will be a
noop (when not handling signals), and upstream suggests fixing it in
sagemath side by saving and restoring pointers when calling
pari_init_opts.
Sage simply removes the mp_set_memory_functions call in the pari spkg, but
I believe my proposed solution is better, and I am doing it in my work to
build a sagemath package using system wide packages.
