libtcc: new LIBTCCAPI tcc_set_options(TCCState*, const char*str)

Browse Source 
This replaces       -> use instead:
-----------------------------------
- tcc_set_linker    -> tcc_set_options(s, "-Wl,...");
- tcc_set_warning   -> tcc_set_options(s, "-W...");
- tcc_enable_debug  -> tcc_set_options(s, "-g");

parse_args is moved to libtcc.c (now tcc_parse_args).

Also some cleanups:
- reorder TCCState members
- add some comments here and there
- do not use argv's directly, make string copies
- use const char* in tcc_set_linker
- tccpe: use fd instead of fp

tested with -D MEM_DEBUG: 0 bytes left
