Detailed Description

POSIX-shaped threading layer shared by the stream engine (zxc_driver.c) and the seekable reader (zxc_seekable.c).

On POSIX this is <pthread.h> verbatim. On Windows it maps the handful of primitives both engines use onto the Win32 API under their POSIX names, so one body of threading logic compiles everywhere. Include this instead of <pthread.h>.
