[PATCH] please make pari_sighandler public

[Jeroen Demeyer <jdemeyer@cage.ugent.be>]

Hello,

this patch is useful for applications which require switching between 
signal handlers (between PARI's handler and a private handler). It also 
allows more fine-grained control than INIT_SIGm to setting up signal 
handlers.

Thanks,
Jeroen.
