Log message:
x11/libxshmfence: Detect max page size correctly.

For cross-builds, whatever sysctl answers is wrong -- and even for
native builds, it may be wrong, because on some architectures with
common binary packages, the page size may vary from machine to
machine.  So use MAX_PAGE_SIZE if available, or PAGE_SIZE if not,
from machine/vmparam.h instead.

XXX Should probably also use COHERENCY_UNIT for cache line alignment,
not hard-coded 128.

Log message:
x11/libxshmfence: TOOL_DEPENDS, not buildlink3, on xorg-util-macros.

Likely need the same for everything that uses xorg-util-macros --
it's needed for running autoconf, not for linking build products
against.

Log message:
libxshmfence: improve performance of semaphore backend. Bump rev.

It used more locking that necessary. We only need two semaphores.
One to tell waiters to wake up and one to let the last waiter that
wakes up notify xshmfence_trigger() it may now return.
