Add safe vsnprintf and snprintf library functions
From: Sonny Rao <sonnyrao@chromium.org>
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.
(Simon Glass <sjg@chromium.org> modified this commit a little)
