* Add framework for resolving (pun intended) libc namespace issues, usingguenther2015-08-312-4/+6
| | | | | | | | | | | | 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@

* restructure libc/string + libc/arch/*/string coperation regardingderaadt2014-11-301-5/+9
| | | | | | | | | | | | | | | | (potentially) MD versions (function dependent, not filename dependent) split out memcpy/memmove/bcopy and strchr/index/strrchr/rindex Bring back amd64 .S versions And the final touch: switch all architectures temporarily to MI memcpy.c, which contains syslog + abort for overlapping copies. A nice harsh undefined behaviour. We will clean the entire userland of the remaining issues in this catagory, then switch to the optimised memcpy which skips the memmove check. I tried to cut this change into pieces, but testing each sub-step on every architecture is too time consuming and mindnumbing. ok miod

(Don't ask me why our makefiles wouldn't accept using strlen.c)
