Fix out of boundary writes in XUtils

It is possible to exceed the unsigned int data type on 64 bit systems
with enough available RAM. Use size_t in all places instead.

Proof of Concept: Create a 4 GB line in .htoprc file and run htop

$ dd if=/dev/zero bs=1024 count=4194304 | tr '\0' 'a' > ~/.htoprc
$ htop
Segmentation fault

Also avoid overflow of stack based "match" array in String_getToken.
