* When encoding fails in fputwc(3), set the error indicator as requiredschwarze2016-01-261-2/+2

Note that an enquiry to the Austin Group led to the conclusion that this change probably violates the C standard: C and POSIX unintentionally conflict. But the POSIX behaviour makes more sense (easier to write correct error handling code for it, and a lower risk that programs miss errors) and is much more widespread, and the Austin Group intends to approach the C committee in order to adjust the C standard. See: http://austingroupbugs.net/view.php?id=1022 While here, do not set errno a second time, wcrtomb(3) already did that, and it is required to do it by the standard. OK millert@ and tedu@, and jca@ no longer objects

* Add framework for resolving (pun intended) libc namespace issues, usingguenther2015-08-311-1/+2
| | | | | | | | | | | | wrapper .h files and asm labels to let internal calls resolve directly and not be overridable or use the PLT. Then, apply that framework to most of the functions in stdio.h, string.h, err.h, and wchar.h. Delete the should-have-been-hidden-all-along _v?(err|warn)[cx]? symbols while here. tests clean on i386, amd64, sparc64, powerpc, and mips64 naming feedback from kettenis@ and millert@ ok kettenis@
* Fix the handle locking in stdio to use flockfile/funlockfilekurt2009-11-091-3/+3
| | | | | | | | | | | | | internally when and where required. Macros in <stdio.h> are updated to automatically call the underlying functions when the process is threaded to obtain the necessary locking. A private mutex is added to protect __sglue, the internal list of FILE handles, and another to protect the one-time initialization. Some routines in libc that use getc() change to use getc_unlocked() as they're either protected by their own lock or aren't thread-safe routines anyway. committing on behalf of and okay guenther@ now that we have install media space available.
