spelling fixes; from paul tagliamonte
any changes not taken noted on tech, but chiefly here i did not take the
cancelation - cancellation changes;

Redo the calculation of the alignment and placement of static TLS data to
correctly take into account the segment p_align. Previously, anything
with a size belong the natural alignment or with alignment larger than
the natural one would either not be intialized correctly, be misaligned,
or result in the TIB being misaligned.

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.
Testing by various, particularly sthen@ and patrick@
