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 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@ ok kettenis@

recv() and send() aren't overriden by libpthread (vs recvfrom() and sendto()!)

so wrap them to make internal calls go direct

getpeereid() and sockatmark() are neither used in libc nor in ISO C, so mark

them deprecated and weak

Add PROTO_WRAP() for (almost) all the syscalls that libpthread doesn't
