vsprintf.h doesn't include the stdarg.h file, which means that it relies on
the files that include vsprintf.h to include stdarg.h as well.
Add an explicit include to avoid build errors when simply including that
file.

Enabling this function always removes some class of string saftey issues.
The size change here in general is about 400 bytes and this seems a reasonable
trade-off.

Split out the code in fdtdec which finds a number at the end of a string. It
can be useful in other situations.

Move common functions from cmd_nand.c (for calculating offset
and size from cmdline paramter) to common place, so they could
used from other commands which use mtd partitions.
For onenand the arg_off_size() is left in common/cmd_onenand.c.
It should use now the common arg_off() function, but as I could
not test onenand I let it there ...

The printf() in panic() adds about 1.5KB of code size to SPL when compiled
with Thumb-2. Provide a smaller version that does not support printf()-style
arguments and use it in two commonly compiled places.

Move bootstage's numbering printing code into a generic place so that it can
be used by tracing also.

Now that this is not in common.h, perhaps it is acceptable to move this
documentation into the header file.

From: Sonny Rao <[email protected]>
These functions are useful in U-Boot because they allow a graceful failure
rather than an unpredictable stack overflow when printf() buffers are
exceeded.
Mostly copied from the Linux kernel. I copied vscnprintf and
scnprintf so we can change printf and vprintf to use the safe
implementation but still return the correct values.

common.h is very large, so before changing the vsprintf functions, move the
prototypes into their own header file.
