Fix known issues which blow up the process after dlopen("libthr.so") (or loading a dso linked to libthr.so into process which was not linked against threading library).
MFC r276630: Remove interposing, fix malloc, reinstall signal handlers wrappers on libthr load.
MFC r276681: Avoid calling internal libc function through PLT or accessing data though GOT.
MFC r277032: Reduce the size of the interposing table and amount of cancellation-handling code in the libthr.
MFC note: r276646 ("do not erronously export 'openat' symbol from rtld") is not applicable to stable/10 yet, since PATHFDS support was not merged.

Because POSIX does not allow EINTR to be returned from sigwait(), add a wrapper for it in libc and rework the code in libthr, the system call still can return EINTR, we keep this feature.
