fs: move libc function prototypes to their correct locations ...

This moves the function prototypes in include/fs.h which also exist
in the libc to the locations they would have in libc.

With this it becomes easier to share code between barebox and userspace
since the usual libc include files will exist. Also users of the libc
functions no longer have to include the barebox internal fs.h header.

fcntl: Fix O_CREAT clashing with O_RWSIZE_8 ...

O_CREAT and O_RWSIZE_8 are both defined as 0100. Fix this by moving the
O_RWSIZE_* flags to unused bits.

This bug leads to incomplete writes when the destination file is created
and mem_write is involved, for example with the memcpy command:

memcpy -s /some/file -d /dev/ram0 0 0 10

In this case only 8 bytes will be copied and it will be done using 8
byte accesses which may not work properly if the destination is not
sufficiently aligned, i.e.:

memcpy -s /some/file -d /dev/ram0 0 1 8

fs: Add O_RWSIZE_8 ...

To support native 64bit accesses in memcpy_sz.

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 V2/barebox/g' \
	-e 's/u-boot v2/barebox/g' \
	-e 's/U-Boot V2/barebox/g' \
	-e 's/U-Boot-v2/barebox/g' \
	-e 's/U_BOOT/BAREBOX/g' \
	-e 's/UBOOT/BAREBOX/g' \
	-e 's/uboot/barebox/g' \
	-e 's/u-boot/barebox/g' \
	-e 's/u_boot/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
