Fix semihosting with latest toolchain 

Fixes issues #10:

https://github.com/ARM-software/tf-issues/issues/10

This patch changes all/most variables of type int to be size_t or long
to fix the sizing and alignment problems found when building with the
newer toolchains such as Linaro GCC 13.12 or later.
