Compressing the logos with lzma rather than gzip saves ~9kb with the
Blackfin 24bit images and ~3kb with the 16bit images.

Add a new -l option to easylogo so people can pick lzma as their
decompression routine.

Currently, some of the tools instead set CC to be HOSTCC in order to re-use
some pattern rules -- but this fails when the user overrides CC on the make
command line.  Also, the HOSTCFLAGS in tools/Makefile are currently not
being used because config.mk overwrites them.

This patch adds static pattern rules for files that have been requested to
be built with the native compiler using $(HOSTSRCS) and $(HOSTOBJS), and
converts the tools to use them.

It restores easylogo to using the host compiler, which was broken by commit
38d299c2db81bd889c601b5dfc12c4e83ef83333 (if this was an intentional change,
please let me know -- but it seems to be a build tool).

It restores -pedantic and the special flags for darwin and cygwin that were
requested in tools/makefile (but keeps the flags added by config.mk) --
hopefully someone can test this on those platforms.  It no longer
conditionalizes -pedantic on not being darwin; it wasn't clear that that was
intentional, and unless there's a real problem it's just inviting people to
contribute non-pedantic patches to those files (I'm not a fan of -pedantic
personally, but if it's on for one platform it should be on for all).

HOST_LDFLAGS is renamed HOSTLDFLAGS for consistency with the previous
HOST_CFLAGS to HOSTCFLAGS rename.  A new HOSTCFLAGS_NOPED is made available
for those files which currently cannot be built with -pedantic, and replaces
the old FIT_CFLAGS.

imls now uses the cross compiler properly, rather than by trying to
reconstruct CC using the typoed $(CROSS_COMPILER).

envcrc.c is now dependency-processed unconditionally -- previously it would
be built without being on (HOST)SRCS if CONFIG_ENV_IS_EMBEDDED was not
selected.

Some images can be quite large, so add an option to compress the
image data with gzip in the U-Boot image. Then at runtime, the
board can decompress it with the normal zlib functions.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

Michael Hennerich added support for outputting an image in RGB format rather
than forcing YUYV all the time.  This makes obvious sense if the display you
have takes RGB input rather than YUYV.

Rather than hack in support for options, I've converted it to use getopt and
cleaned up the argument parsing in the process.

didnt realize how out of shape easylogo actually was until i tried using it.
this patch does byte swapping as need be on the input tga header since the tga
is in little endian but the host could just as well be big endian.  i didnt
bother using bswap macros or such stuff from system headers as nothing in
POSIX dictates byte swapping functionality.

- make the Makefile not suck
- include proper headers for prototypes
- fix obvious broken handling of strchr() when handling '.' in filenames
