Using calloc() instead of malloc() as preventive measure, so there
never can be any hidden bugs or leaks due uninitialized memory.
The extra cost of using this compiler intrinsic should be practically
impossible to measure - in many cases a good compiler can even deduce
if certain areas really don't need to be zero'd (because they're written
to right after allocation) and create more efficient machine code.
The code pathes in question are pretty cold anyways, so it's probably
not worth even thinking about potential extra runtime costs.

Convert clipboard integration code from libX11 to xcb
This drops support for COMPOUND_TEXT. Presumably some ancient
(pre-2000) clients exist which support that, but not UTF8_STRING, but we
don't have an example to test with. (Given the nature of the thing, the
users of those clients probably work in CJK languages)
Supporting COMPOUND_TEXT would also involve writing (or extracting from
Xlib) support for the ISO 2022 encoding.
v2:
Fix the length of text property set by a SelectionRequest
The length of the text property is not neccessarily the same as the
length of the clipboard text before it is d2u converted (specifically,
if that contains any '\r\n' sequences, it will be shorter as they are
now just '\n')
Including any server header might define the macro _XSERVER64 on 64 bit
machines. That macro must _NOT_ be defined for Xlib client code, otherwise bad
things happen. So let's undef that macro if necessary.
Remove server directories from include path to ensure no server includes are
included
