[liba] Update the size_t type definition

Browse Source 
size_t must be an unsigned it. Moreover, by definition, size_t is the
return type of the "sizeof" operator, which is defined by the compiler.
Both GCC and clang define a __SIZE_TYPE__ macro to let the libc header
know about the type used by the sizeof operator.
