our mbrtowc(3) is not in conformance to POSIX specification

[Takehiko NOZAKI]

opengroup's specfication says:

If s is a null pointer, the mbrtowc() function shall be equivalent to the call: mbrtowc(NULL, "", 1, ps)

but our implementation force to initialize the mbstate_t(=ps) incorrectly.

reopen, this fix causes sysinstall trouble, sysinstall don't show any chatacter after setect language and call setlocale(3) internally.

[Takehiko NOZAKI]

this sysinstall bug introduced by _fixup_ps() change. the _RuneLocale embedded in mbstate_t is not same as current locale, raise EINVAL.

but this change give impact on some i18n'ed application/library(ex. sysinstall/libcurses). so i simply change:

1. don't throw EINVAL.
2. initialize mbstate_t silently.
