* configure.ac: Check for more headers, functions.
* mf-hooks2.c (mkbuffer, unmkbuffer): New helper functions for
tracking overridden FILE buffers.
(fopen, setvbuf): New/revised hook functions for buffer overriding.
(setbuf,setlinebuf,fdopen,freopen,fopen64,freopen64,fclose): Ditto.
(fflush): Accept given NULL stream (means "all streams").
* mf-runtime.h.in:
* mf-runtime.c (__mfu_check): Accept accesses that span adjacent
HEAP/GUESS objects.
(LOOKUP_CACHE_SIZE_MAX): Raise to 64K entries tentatively.
(__mf_adapt_cache): Use them all.
* testsuite/libmudflap.c/pass35-frag.c: Update warning message.
* testsuite/libmudflap.c++/ctors.exp: Ditto.
* testsuite/libmudflap.c/{pass51,pass52}-frag.c: New tests.
