- Remove charset parameter from low level __foo_wctomb/__foo_mbtowc calls. - Instead, create array of function for ISO and Windows codepages to point to function which does not require to evaluate the charset string on each call. Create matching helper functions. I.e., __iso_wctomb, __iso_mbtowc, __cp_wctomb and __cp_mbtowc are functions returning the right function pointer now. - Create __WCTOMB/__MBTOWC macros utilizing per-reent locale and replace calls to __wctomb/__mbtowc with calls to __WCTOMB/__MBTOWC. - Drop global __wctomb/__mbtowc vars. - Utilize aforementioned changes in Cygwin to get rid of charset in other, calling functions and simplify the code. - In Cygwin restrict global cygheap locale info to the job performed by internal_setlocale. Use UTF-8 instead of ASCII on the fly in internal conversion functions. - In Cygwin dll_entry, make sure to initialize a TLS area with a NULL _REENT->_locale pointer. Add comment to explain why.
