Portability improvements, e.g., libmudflap/15293.
* configure.in: Look for glibc extension functions. Look for
support of -f{function,data}-sections. Look for more headers.

mf-hooks* into usual single object per source.
* mf-hooks*.c: Remove all #if WRAP_foo conditionals.
* mf-hooks2.c: #include a bunch more system headers. Define strnlen
if system doesn't provide one.
* mf-hooks3.c (struct pthread_info): Add stack_*_alloc fields.
(pthread_create): Use it to properly GC dead thread stacks.
* mf-runtime.c (__mf_violation): Correct snprintf type warning.
* testsuite/Makefile.am: Stop generating site.exp.
