filesystem encoding on Mac OS X is now
default external encoding. so Mac OS X is now
treated as one of Unix. [ruby-dev:40439]
* file.c (file_path_convert): ditto.

encoding because on resetting default_external because
Unix's filesystem encoding depends on default_external.
* encoding.c (enc_set_filesystem_encoding): added.
* ruby.c (process_options): don't call rb_filesystem_encoding
because filesystem encoding is reset when default_external
is reset.

* encoding.c (rb_enc_set_base): Add for setting base encoding
with their names. this is internal function.
* template/encdb.h.tmpl: specify ENC_SET_BASE for second
encodings in each encoding files.
* enc/encdb.c (rb_enc_set_base): add a declaration.

whether code page is used.

* encoding.c (rb_locale_charmap): use environments on mingw and mswin.
* missing/langinfo.c (nl_langinfo_codeset): MS-Windows Japanese
environment uses Windows-31J derived from Shift_JIS, not EUC-JP.

GetACP() because external encoding should be console's one.
* encoding.c (rb_filesystem_encoding): use GetOEMCP() instead of
GetACP() because VFAT/FAT32 uses OEM CP.

Generalizing rb_default_{external,internal}_encoding seems to be
difficult.
default_external cannot be NULL even before detected. [ruby-dev:37390]
* encoding.c (rb_default_external_encoding): has its own
implementation again.
* encoding.c (rb_default_internal_encoding): ditto.
* gem_prelude.rb: added notice.
* ruby.c (rubylib_mangled_path, rubylib_mangled_path2): uses locale
encoding but not ASCII-8BIT.
* ruby.c (process_options): refers less to default_external.
