some none-default fonts currently do not display combining accents.

OK bentley@, and the general direction was also supported by stsp@.
re-proposed by Julien Steinhauser with an updated diff. Apparently this was in
the original calmnwm.
However, expand the original idea and let clients 'snap' to edges instead,

*and* window.) of mousefunc.c. When a client destroys itself while we are
moving or resizing it, XWindowEvent() blocks. Found the hard way by Anton
Lazarov, and Lea°hNeukirchen found the right bit to revert - thanks! Reverting

The latter is an obsolete non-standard, Linux only synonym for the
former. This caused syndaemon(1) to enter an an infinite loop whenever
it receives a SIGINT signal. Patch from Luca Castagnini. Thanks.

addition of these checks]
This addresses CVE-2017-12179
v2: Add overflow check and remove unnecessary check (Julien Cristau)
This addresses:
CVE-2017-12184 in XINERAMA
CVE-2017-12185 in MIT-SCREEN-SAVER
CVE-2017-12186 in X-Resource
CVE-2017-12187 in RENDER
A client can send a big request where the 32B "length" field has value

touch memory beyond the receive buffer.
