Add private MIME DB classes to libbe_build

* This pulls in some more stuff, like libicon and agg which are also
included in libbe_build, now.
* Update a few libbe_build classes and headers needed to get things
building.
* This likely breaks the <build>mimeset build on Haiku.

* Added KMessage to libroot_build.
* libbe_build: Where possible we directly use the actual Haiku headers and
sources, now. In the headers/build headers we just include the respective
Haiku headers as needed. That still allows overrides where necessary. The
intention is to make it easier to keep the build stuff in sync.
* Fixed a few printf() format and signed/unsigned comparison warnings.

Make use of the UsePrivateBuildHeaders rule.

some make system work to get x86-64 linux compiles working:
-The biggest problem with linking host libraries (libbe_build and libroot_build) was not having the source files compiled with the -fPIC flag. As far as I can tell, we want to do this on all of the other host platforms as well, so hacked the jam files a bit to add it.
Forgive me if I've committed more Jamfile sins.
