Declare pthread_atfork as weak to avoid a fatal error with LLVM 13
Fixes behavior with current clang, which marks the symbol as GLOBAL
instead of WEAK. LLVM change: https://reviews.llvm.org/D90108
base-gcc is unaffected. Keep asm(".weak") for gcc3 until a cleanup can
be tested there.

Declare the symbols that label the .ctors, .dtors, .eh_frame, and .jcr sections as extern hidden arrays of indefinite size, so that the compiler (well, clang) doesn't believe it knows the exact contents and thus optimize things into infinite loops. Actually set the symbols to be in the sections and insert the leading and trailing values via __asm(). Problem pointed out by patrick@ testing and ok kettenis@

Make pthread_atfork() track the DSO that called it like atexit() does, unregistering callbacks if the DSO is unloaded. Move the callback handling from libpthread to libc, though libpthread still overrides the inner call to handle locking and thread-library reinitialization. Major version bump for both libc and libpthread. verification that this fixes various ports ajacoutot@ asm assistance miod@; ok millert@ deraadt@

Move atexit(3) into crtbegin.c and certbeginS.c such that we can pass the right __dso_handle and have dlopen'ed shared objects run their atexit handlers when they get unloaded. This is what Linux does, and several ports depend on this behaviour (and will crash upon exit without this chang). Based on an earlier diff from matthew@ Tested by ajacoutot@ ok deraadt@

Add __guard_local as a hidden symbol to ld.so, kernel, and every executable and DSO (via crtbegin.c/crtbeginS.c). Not used yet, but needed before GCC can start emitting -fstack-protector code that uses them instead of __guard.

add finalized guard to destructor calls, to prevent multiple calls. stop most kde apps from burping all over the place on exit, which means that, somehow, our destructors get registered twice... :-( Okay drahn@

Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

Commonize csu code for elf systems, powerpc now no longer has it's own versions of these files. Fixed a bug in ld.so in this, instead of scheduling the fini of each of the shared libraries with atexit. schedule a function of ld.so itself and it will walk all of the open libraries when the program exits. otherwise a shared library could be dl_open()ed and then dl_close()d and then it would not be mapped for the atexit processing. TODO: What if atexit is not found (process did not link against libc?) Do shared libraries that are dl_closed have their global destructors run?
