PetscCheckPointer: speed up check by using existing signal handler

Registering the special signal handler dominates the cost of these
checks. Here we use the existing (default) signal handler. This has
a race condition in the presence of threads, though SEGV is typically
a "bad enough" condition that threads shouldn't race for it. In any
case, all the signal() based error handling is also ill-defined for
threads. To make this correct and non-racy with threads, we'll need:

1. use thread-local storage for the flag PetscSegvJumpBuf_set

2. use sigaction instead of signal (requires overhauling signal.c)

This commit changes behavior in case a user has registered their own
signal handler, but that change should only be observable when a SEGV
is raised, and may be avoided with -check_pointer_intensity 0.

Merge branch 'barry/fix-nonew-notcollective/maint' into jed/mat-assembly-perf

Jed this fucking 6+ month running thing in next that is not in master is a royal fucking pain in the ass and
an abuse of git. I think it is not justified to ever have anything in next for more than a few weeks at most.
Either take it out of next if it is broken or put it in master if it is not broken. Hanging around in next but
not master for ever is not a good policy.
