with {uint offset, uint syscall#} entries in libc & ld.so.
In libc a few syscall# entries (break, sigprocmask, _tfork, _threxit)
are duplicated because additional or inline uses occur (that situation
is handled elsewhere)

Use a Thread Information Block in both single and multi-threaded programs.
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.

Adds hidden _libc_FOO aliases for the system call stubs.
Stop generating _brk and _sbrk symbols: they've already been hidden.

Give the __{min,cur}brk symbols a size and type, and hide more jump labels.

fact that #128 and #129 may also be used for this purpose was never documented,
so there is no reason to have libc use #128. Switch to #450 for consistency.

Rename cerror to __cerror and curbrk to __curbrk, to avoid namespace
pollution. Conforming to art@'s evil plans.

correted sigsetjmp, setjump. Fixed MACHINE_ARCH vs. MACHINE stuff.
