* wcsmbs/mbrtowc.c: Set flush to 1 for conversion function calls
depending on whether the input string is empty or not.
* wcsmbs/mbrtowc.c: Calling function without input means clearing the
given state and not avoiding this by modifying a local object.
* wcsmbs/wcrtomb.c: Likewise.
* iconv/skeleton.c: If no EMIT_SHIFT_TO_INIT is defined clear state
object since some incomplete characters might be in there.
* locale/programs/ld-ctype.c (ctype_finish): Take all characters from
the input charset into account when generating the hash table.
(allocate_arrays): Correct setting default width. Not all empty slots
in the table are filled, only those not covert explicitly by the
locale description and in the charset.
* stdio-common/vfscanf.c: Make sure to always return WEOF and EOF for
wide character version.
For %C handling, test correct pointer variable for NULL.
* wcsmbs/wctob.c: Handle WEOF special.
* wcsmbs/wcwidth.h: 0xff in width array means invalid character.
* wctype/wctype.h: Protect gcc-isms with __extension__. Avoid
always-true test to avoid warning.
comment them out for now.
(subdir-dirs): New for tests-mbwc, add also vpaths.
* Makefile (tests): Add tests from tests-mbwc subdirectory,
