The current SIGIO signal handler method, used at generation of input events,
has a bunch of oddities. This patch introduces an alternative way using a
thread, which is used to select() all input device file descriptors.
A mutex was used to control the access to input structures by the main and input
threads. Two pipes to emit alert events (such hotplug ones) and guarantee the
proper communication between them was also used.

v2: Fix non-Xorg link. Enable where supported by default.
This also splits out the actual enabling of input threads to
DDX-specific patches which follow
v3: Make the input lock recursive
v4: Use regular RECURSIVE_MUTEXes instead of rolling our own
Respect the --disable-input-thread configuration option by
providing stubs that expose the same API/ABI.
Respond to style comments from Peter Hutterer.
v5: use __func__ in inputthread debug and error mesages.
Respond to style comments from Peter Hutterer.
v6: use AX_PTHREAD instead of inlining pthread tests.

v7: Use pthread_sigmask instead of sigprocmask when using threads
