Log Message:
Update xkbcomp to 1.3.1:

Couple of minor fixes, the only user-visible change is that the warning when
a key type is shortened is now on a verbosity level above the default
verbosity. This effectively removes the warning below for all users of the
german keyboard layout (and others):
  Type "ONE_LEVEL" has 1 levels, but <RALT> has 2 symbols

Alan Coopersmith (1):
      Stop including <X11/Xalloca.h> in parseutils.c

Jon TURNEY (1):
      Define WIN32_LEAN_AND_MEAN when building on Win32

Matthew Green (1):
      Adjust a NUL-string assignment to avoid const issues.

Peter Hutterer (2):
      symbols: increase the warning level for shortening a key type
