Krzysztof Halasa c5baa0edc4 Fix error handling with malloc, memalign etc. Introduce xmemalign(). 
The idea is to panic() when there is no memory available for normal
operation. Exception: code which can consume arbitrary amount of RAM
(example: files allocated in ramfs) must report error instead of panic().

This patch also fixes code which didn't check for NULL from malloc() etc.

Usage: malloc(), memalign() return NULL when out of RAM.
xmalloc(), xmemalign() always return non-NULL or panic().

Sascha Hauer a3ffa97f40 rename U-Boot-v2 project to barebox 
This has been done with the following script:

find -path ./.git -prune -o -type f -print0 | xargs -0 -r sed -i \
	-e 's/u2boot/barebox/g' \
	-e 's/U2Boot/barebox/g' \

	-e 's/U-Boot/barebox/g' \
	-e 's/U-boot/barebox/g' \
	-e 's/U-BOOT/barebox/g'

find -path ./.git -prune -o \( -name "*u-boot*" -o -name "*uboot*" -o -name "*u_boot*" \) -print0 | \
	xargs -0 -r rename 's/u[-_]?boot/barebox/'

It needs some manual fixup following in the next patch

Sascha Hauer 420a3173f0 commands: remove maxargs 
No need to check for maximum argument counts. The commands are
safe to be called with more arguments, so lets safe some bytes.
