* Fix PermissionError when importing trio due to trying to
access pthread.
* Breaking change: Timeout functions now raise ValueError if
passed math.nan. This includes trio.sleep, trio.sleep_until,
trio.move_on_at, trio.move_on_after, trio.fail_at and
trio.fail_after.
* Added support for naming threads created with
trio.to_thread.run_sync, requires pthreads so is only
available on POSIX platforms with glibc installed.
* trio.socket.socket now prints the address it tried to connect
to upon failure.
* Fixed a crash that can occur when running Trio within an
embedded Python interpreter, by handling the TypeError that
is raised when trying to (re-)install a C signal handler.
* Fix sniffio.current_async_library() when Trio tasks are
spawned from a non-Trio context (such as when using
trio-asyncio). Previously, a regular Trio task would inherit
the non-Trio library name, and spawning a system task would
cause the non-Trio caller to start thinking it was Trio.
* Documented that Nursery.start_soon does not guarantee task
ordering.
