Update aliceml to use git version of Alice ML

This allows 64 bit builds of Alice ML and removes the need for old
versions of gcc to build.

The license is changed to 'mit' from the 'bsd' that it was previously
as the COPYING files in the alice and seam repositories appear to be
the modern style MIT variant (also known as the ICU variant).

Added myself as the maintainer.
new package: xwayland
update weston: add xwayland support

Additionally, add support for more external features as well as more
sound system types.
uclibc: fix url, update

disable verbose logging for XServer, fixes #4333

The current options for the XServer produce a huge amount of log messages. The
server produces around 70-80 messages per minute. The most messages look like
this:

display-manager-start[1846]: GetModeLine - scrn: 0 clock: 75200
display-manager-start[1846]: GetModeLine - hdsp: 1366 hbeg: 1414 hend: 1478 httl: 1582
display-manager-start[1846]: vdsp: 768 vbeg: 772 vend: 779 vttl: 792 flags: 9

Since theses messages aren't very useful, I propose to remove the `-logverbose`
and `-verbose` options from the XServer arguments.
