Add ENTRY_NB() macro for doing an ASM function entry without setting the binding to global (NB == "no binding"), as clang 13 is now warning about changing the binding from global to weak.
This first pass does amd64 and sparc64 and pulls DEFS.h out of the per-arch directory to a common directory; others to follow

Add framework for resolving (pun intended) libc namespace issues, using 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

Sprinkle END() in some straightforward *.S files that have ENTRY(). The resulting *.o have "FUNC" symbols with size set.

restructure libc/string + libc/arch/*/string coperation regarding (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

One of these optimized stubs creates some incredibly subtle damage, causing as(1) to create a wrong nop-sled for text segment aligns. Revert, until it is found and fixed.

Add amd64 assembler versions of some standard functions to libc. The code is already used in the kernel and the files are unmodified copies from src/sys/lib/libkern/arch/amd64/. Depending on the function, this gives us some speedup in userland.
