c2df38c9d3 mirror: Use libev to provide an event loop inside the mirror thread 
We're doing this so we can implement bandwidth controls sanely.

b29ef6d4de flexnbd status: Avoid a possible NULL dereference reading migration status 
While the mirror mutex is taken, the mirroring can be abandoned and serve->mirror
set to NULL, so we need to lock around reading information from serve->mirror

We'll be using this in proxy mode later

22bea81445 Don't open the control socket until after the server socket is bound 
This makes it easier for the tests (and supervisor) to guarantee to be
able to connect to the server socket.

Also this patch moves freeing the mirror supervisor into the server
thread.

4790912750 Remove listen mode 
Changing behaviour so that instead of rebinding after a successful
migration and continuing as an ordinary server, we simply quit with a
0 exit code and let our caller restart us as a server if they want to.
This means that everything in listen.c, listen.h, and anything making
reference to a rebind address is unneeded.

Spoiler: they're the same thing. Added a `rake man` task to build the
man page.  Depends on asciidoc.

This is going to be used for the DIRECT_IO flag.

f3f017a87d Free all possibly held mutexes in error handlers 
Now that we have 3 mutexes lying around, it's important that we check
and free these if necessary if error() is called in any thread that can
hold them.  To do this, we now have flexthread.c, which defines a
flexthread_mutex struct.  This is a wrapper around a pthread_mutex_t and
a pthread_t.  The idea is that in the error handler, the thread can
check whether it holds the mutex and can free it if and only if it does.
This is important because pthread fast mutexes can be freed by *any*
thread, not just the thread which holds them.

Note: it is only ever safe for a thread to check if it holds the mutex
itself.  It is *never* safe to check if another thread holds a mutex
without first locking that mutex, which makes the whole operation rather
pointless.

8691533d88 Added hopeful default path to find rake_utils, turned undefined function 
warnings into errors, and added expensive header scanning to .c->.o rule to
ensure changes to .h files cause recompiles as you'd expect.
