Removing casts from code

[Art Haas]

Hi.

This patch is a test-the-waters patch from me. In many places in the
code, the pointer returned from malloc() and friends is cast. In many
other bits of code, there is no cast. As the cast can hide a potential
bug of not including the needed header file, and the removal of the cast
makes the code a teeny-tiny bit smaller, I'm wondering if a set of
cast-removal patches like the one here would be considered worthwhile by
the main developers. If so, I'll start sending a few in. If not, then
trash this patch and I'll look for other smaller or "janitorial" type
fixes I can work on.
