* cygheap.cc (cygheap_init): Set Cygwin default locale values.

Browse Source 
* cygheap.h (struct cygheap_locale): New structure.
	(struct user_heap_info): Add cygheap_locale member locale.
	* dcrt0.cc (dll_crt0_1): Revert to calling _setlocale_r so that only
	the applications locale is reverted to "C".
	* environ.cc (environ_init): Remove unused got_lc variable.
	* fhandler.h (class dev_console): Remove now unsed locale variables.
	* fhandler_console.cc (fhandler_console::get_tty_stuff): Remove
	setting dev_console's locale members.
	(dev_console::con_to_str): Use internal locale settings.  Default to
	__ascii_wctomb if charset is "ASCII".
	(fhandler_console::write_normal): Ditto.
	* strfuncs.cc (__ascii_wctomb): Drop declaration.
	(__db_wctomb): Use fixed value 2 instead of not
	necessarily matching MB_CUR_MAX.
	(__eucjp_wctomb): Use 3 instead of MB_CUR_MAX.
	(sys_cp_wcstombs): Remove special case for "C" locale.
	(sys_wcstombs): Implement here.  Use internal locale data stored on
	cygheap.
	(sys_cp_mbstowcs): Remove special case for "C" locale.
	(sys_mbstowcs): Implement here.  Use internal locale data stored on
	cygheap.
	* syscalls.cc (internal_setlocale): New function to set cygheap locale
	data and to reset CWD posix path.
	(setlocale): Just call internal_setlocale from here if necessary.
	* wchar.h (__ascii_wctomb): Declare.
	(sys_wcstombs): Don't define inline, just declare.
	(sys_mbstowcs): Ditto.

/* Set the console charset and the mb<->wc conversion functions from
the current locale the first time the shared console info is created.
When this initialization is called, the current locale is the one
used when reading the environment. This way we get a console setting
which matches the setting of LC_ALL/LC_CTYPE/LANG at the time the
first Cygwin process in this console starts.
This has an interesting effect. If none of the above environment
variables is set, the setting is equivalent to before when
CYGWIN=codepage was not set: The console charset will be the
default ANSI codepage. So it's sort of backward compatible.
TODO: Find out if that's a feasible approach. It might be better
in the long run to have a distinct console charset environment
variable. */
