Now that the other architecture-specific lib directories have been
moved out of the top-level directory there's not much reason to have the
'_generic' suffix on the common lib directory.

Shove a lot of the HOSTCC and related #ifdef checking crap into the new
compiler.h header so that we can keep all other headers nice and clean.

Also introduce custom uswap functions so we don't have to rely on the non
standard implementations that a host may (or may not in the case of OS X)
provide.  This allows mkimage to finally build cleanly on an OS X system.

    tools/mkimage: fix compiler warnings on some systems.

Broke building on some systems, because the host's string.h was interfering
with u-boot's linux/string.h.  It doesn't look like we need the u-boot one if
we're building for the host, so now we only include when building inside
u-boot.

Some files didn't get updated properly with the "Use watchdog-aware
functions when calculating hashes of images" commit, this commit
fixes this.

Implement watchodg-aware variants of hash calculation functions:
- crc32_wd()
- md5_wd()
- sha1_csum_wd()
The above functions calculate the hash of the input buffer in chunks,
triggering the watchdog after processing each chunk. The chunk size
is given as a function call parameter.

Some systems have md5.h installed in /usr/include/. This isn't the
desired file (we want the one in include/md5.h). This will avoid the
conflict. This fixes the host tools building problem by creating a new
directory for U-Boot specific header files.

MD5 supoprt is turned on by defining CONFIG_MD5, the digest can be then
calculated using the md5() function -- see include/md5.h for details.
