3ff119aa1d (put_unwind_info): New function. 
(resume): Likewise.
(nop): Remove.
(main): Don't cast function pointer to different prototypes.  That's apparently
	not allowed.  icc v8.0 complains about it and GCC 3.5 will actually
	generate crashing code when this is done.  Talk about terminated with
	extreme prejudice!

Add a new test-program (run-ptrace-mapper) to verify that

	have a huge number of mappings.

(main): Support command-line option -c to turn on caching of
	unwind-info and -n to turn off the printing (and lookup)
	of symbol names.
	Stop execution if child dies with a signal.

5de4b351e7 (struct map_iterator): Add members "buf_size", "buf", and "buf_end". 
(maps_init): Try to mmap() a one-page buffer and, if successful,
	initialize the new map_iterator members based on it.
(maps_next): If the one-page buffer is available, use it to read
	/proc/PID/maps.  This avoids expensive lseek() calls which,
	in the case of /proc lead to T(n) = O(n^2) behavior.

6840f3c057 Allow libunwind to be built without any optimization. 
This means that it will no longer be possible to validate at
link-time certain assertions.  Instead, there will be assertion
failures at library initialization-time when debugging is enabled
(--enable-debug).

(validate_cache): If HAVE_DL_PHDR_REMOVALS_COUNTER is defined, use
	dl_phdr_removals_counter() to validate the cache.  This is
	much more efficient than using dl_iterate_phdr(), since it
	avoids locking.
