xf86-video-modesetting: Add ms_queue_vblank helper [v3]
This provides an API wrapper around the kernel interface for queueing
a vblank event, simplifying all of the callers.
v2: Fix missing '|' in computing vbl.request.type
v3: Remove spurious bit of next patch (thanks, Michel Dänzer)

xkb: Handle xkb formated string output safely (CVE-2017-13723)
Generating strings for XKB data used a single shared static buffer,
which offered several opportunities for errors. Use a ring of
resizable buffers instead, to avoid problems when strings end up
longer than anticipated.

xkb: Escape non-printable characters correctly.
XkbStringText escapes non-printable characters using octal numbers. Such escape
sequence would be at most 5 characters long ("\0123"), so it reserves 5 bytes
in the buffer. Due to char->unsigned int conversion, it would print much longer
string for negative numbers.
