[PATCH] Fix bounds check in vsnprintf, to allow for a 0 size and NULL buffer
...
This change allows callers to use a 0-byte buffer and a NULL buffer pointer
with vsnprintf, so it can be used to determine how large the resulting
formatted string will be.
Previously the code effectively treated a size of 0 as a size of 4G (on
32-bit systems), with other checks preventing it from actually trying to
emit the string - but the terminal \0 would still be written, which would
crash if the buffer is NULL.
This change changes the boundary check so that 'end' points to the putative
location of the terminal '\0', which is only written if size > 0.
vsnprintf still allows the buffer size to be set very large, to allow
unbounded buffer sizes (to implement sprintf, etc).
