Make the early console device/baudrate configurable instead of using ...

hardcoded values

[general] Fixed crash in memory allocator ...

Fixed a bug in sbrk(). When the new mem_brk value returned by
sbrk_no_zero() returns NULL to indicate 'out of memory', sbrk()
still memset()s innocent memory at address NULL.

For some architectures this memory might be empty, so this never
causes a problem. Anyway on Coldfire I still have my vector table
there. Nuking them isn't really a good idea :-)

- Add functions to register image handlers for booting uImages

[general] Fixed endian handling for envfs ...

Fixed the handling of data similiar as found in cramfs.

This fixes the problem with an unreadable defaultenv on big-endian
targets.

The endian macors are now loaded from /asm/common.h by default.
