This stores errno, the cancelation flags, and related bits for each thread
and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable!
Make libpthread dlopen'able by moving the cancelation wrappers into libc
and doing locking and fork/errno handling via callbacks that libpthread
registers when it first initializes. 'errno' *must* be declared via
<errno.h> now!
Clean up libpthread's symbol exports like libc.
On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec.

into libc, and move pthread_sigmask() as well (just a trivial wrapper).
This provides consistent handling of SIGTHR between single- and multi-threaded
programs and is a step in the merge of all the libpthread overloads, providing
some ASM and Makefile bits that the other wrappers will need.

Stop generating _brk and _sbrk symbols: they've already been hidden.
Set the ELF symbol size on the syscall stubs.
Give the __{min,cur}brk symbols a size and type, and hide more jump labels.

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.

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.

A while back, pascal@ converted our system call stubs from using "cpp
| as" to "cc -x assembler-with-cpp", so there's no need to stay
compatible with ancient preprocessor semantics.

invocations. This allows us to use the compiler builtin define __PIC__ to check
for PIC/PIEness rather than passing -DPIC. Simplifies PIE work a lot.

to 'as' to make it compile pic. add defaults for sparc64 which needs picflags
set to -fPIC and ASPICFLAGS to -KPIC.
Also simplifies the systemcall generation for sparc64 PIC mode.
