Add compat/snprintf.c for systems that return bogus
Some systems (namely HPUX and Windows) return -1 when maxsize in snprintf()
and in vsnprintf() is reached. So replace snprintf() and vsnprintf()
functions with our own ones that return correct value upon overflow.
[jc: verified that review comments by J6t have been incorporated, and
tightened the check to verify the resulting buffer contents, suggested
by Wayne Davison]
