Introduce _STDIO_BSD_SEMANTICS flag to switch fclose/exit file flushing
semantics from POSIX to BSD.
* libc/stdio/fclose.c (_fclose_r): Conditionalize file flushing on
_STDIO_BSD_SEMANTICS. Call __sflush_r rather than _fflush_r. Add
comment.
* libc/stdio/fflush.c (__sflushw_r): New function, only available
if _STDIO_BSD_SEMANTICS is defined.
* libc/stdio/findfp.c (_cleanup_r): Call _fwalk_reent rather than
_fwalk. Conditionalize cleanup function call on _STDIO_BSD_SEMANTICS.
Add comments. Add FIXME.
* libc/stdio/local.h (__sflushw_r): Declare if _STDIO_BSD_SEMANTICS is
defined.
