bakkeby 36cbcf53a2 IPC: do not bail on events from unknown file descriptors ref. #433 
The natural cycle for dwm-msg is that:
   - the client registers
   - the client sends a message
   - a response is sent back
   - the client deregisters

There is a race condition such that a new client may end up with the same
file descriptor as another command that is deregistering, resulting in a
message to come through from a file descriptor that is not registered.

The handling of this situation is that the IPC patch will log:

   Got event from unknown fd 7, ptr 0x7, u32 7, u64 7 with events 17

before gracefully stopping (exiting) dwm.

The consequence of the error itself seems benign and the proposal here is
to allow dwm to keep running despite not being able to process the dwm-msg
command successfully.

*
* dynamic window manager is designed like any other X client as well. It is
* driven through handling X events. In contrast to other X clients, a window
* manager selects for SubstructureRedirectMask on the root window, to receive
* events about window (dis-)appearance. Only one X connection at a time is
* allowed to select for this event mask.
*
* The event handlers of dwm are organized in an array which is accessed
* whenever a new event has been fetched. This allows event dispatching
* in O(1) time.
*
* Each child of the root window is called a client, except windows which have
* set the override_redirect flag. Clients are organized in a linked client
* list on each monitor, the focus history is remembered through a stack list
* on each monitor. Each client contains a bit array to indicate the tags of a
* client.
*
* Keys and tagging rules are organized as arrays and defined in config.h.
*
* To understand everything else, start reading main().
