include: always unsigned long for size_t

Using the definition that GCC provides, size_t is an 'unsigned int' on
32-bit platforms and 'unsigned long' on 64-bit platforms. This is a
constant source of compatibility problems, since code is often written
for one integer type and then fails to compile for the other (e.g.
printf format specifiers). 'unsigned long' always matches the platform
size (see uintptr_t in <stdint.h>), so use it for size_t everywhere.
This also removes a weird macro hack for defining ssize_t.
