moved MEM_LIBC_MALLOC code from mem.h to mem.c:
...
- it's not worth littering mem.h just to save some bytes to prevent the additional call;
- MEM_STATS now also work when MEM_LIBC_MALLOC is enabled

Implement portable and overridable allocation of memory buffers

Fixes bug #48300 (Private mempools allocate foreign memory), bug #48354 (Portable alignment defines/include required for static allocation) and bug #47092 (Tag memory buffers like memp_memory_xxx and ram_heap with a macro so that attributes can be attached to their definitions)

mem.c: Fix unintended sign extension (found by Coverity)
...
sign_extension: Suspicious implicit sign extension: count with type unsigned short (16 bits, unsigned) is promoted in count * size to type int (32 bits, signed), then sign-extended to type unsigned long (64 bits, unsigned). If count * size is greater than 0x7FFFFFFF, the upper bits of the result will all be 1.
