Enable EFIv1 compression in bmpbklk_utility.

Enable EFIv1 compression in bmpbklk_utility.

This lets bmpbklk_utility generate BMPBLOCKs with EFIv1-compressed bitmaps.
It also adds the ability to display or unpack BMPBLOCK blobs.

The compression/decompression routines come from the tianocore EDK on
sourceforge and are written in C, so now there's a mix of C and C++, but it
works just fine.

File utility/bmpblk_util.c (right):

utility/bmpblk_util.c:65: static int require_dir(const char *dirname) {
Could move this to host/lib so we can share it with other firmware utils
(pack/unpack kernel blob, etc.)

I tried; hostlib fights with all the various include files and the g++ compiler.
Not worth it.

(LGTM regardless)

LGTM

The path of bmpblk_util.h header file should be utility/include/ instead of
firmware/include/.
