Added 2 checks to mapping function - one for overflow (virtual address +
size wraparound), one to see if the size fits in the designated segment.

It seems this check wasn't done. This came to light when trying to pre-check
the users buffer for read() and write() in using the vectored virtual
copy system call in servers/fs/read.c.
