libreboot-utils: optimised string functions
operate per word, not per byte
this is also done on sdup, which uses a slightly
inefficient method: the new string allocation is
that of the maximum size, rather than what we
need. for example, if you wanted a 20 character
string (21 including null), you would still allocate
4096 bytes if that was the maximum length.
it's a bit naughty, and i have half a mind to
keep sdup on the old implementation, but i'll leave
it be for now.
