trurl 8c68f95291 Update calls to malloc/free, etc., to use wmalloc/wfree/... 
This fixes a lot of memory bugs which arose as a result of doing something
different from the system malloc/free when allocators were rewritten in Rust.

These changes originate from a different approach to writing the allocator in
Rust:
https://git.sdf.org/vitrine/wmaker/pulls/1/files#diff-04a0fd2319b9969373b75377716e45c836d22869

There are other function calls (to XFree) that need to be fixed, but that can be
done in another commit. This one is already getting large.
