Update.
* iconv/gconv_open.c (__gconv_open): Empty codeset name now means using the current locale's codeset. * iconv/iconv_open.c (iconv_open): Don't strip out everything for empty input string. * iconv/iconv_prog.c: Pass empty strings as default value for to- and from-charset. Don't determine locale's charset here. if libio is used [PR libc/2575].

+
* libio/genops.c (_IO_flush_all_lockp): New function. The same code
as the old _IO_flush_all but lock only if parameter is nonzero.
(_IO_flush_all): Call _IO_flush_all_lockp with 1 as parameter.
* libio/libioP.h: Add prototype for _IO_flush_all_lockp.
* sysdeps/generic/abort.c (fflush): Define to _IO_flush_all_lockp(0)
- if libio is used.
