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!

When the syscall number has to be loaded from a pc-relative location, abuse END macros to place the number at the end of the syscall wrapper rather than in the middle of it, so that there is no need to branch around it; this saves two instructions per syscall number >= 128.

Adds hidden _libc_FOO aliases for the system call stubs. 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.
