Bump PKGREVISION

Log message:
Put back PKGREVISION=1. It was there on purpose, to make it clear that
there are extra (security) patches and it's not the stock 4.6.6 or 4.8.2

Log message:
xen*[46]*: reset PKGREVISION after update

Log message:
Update xentools48 and xenkernel48 to 4.8.2, and apply security patches up
to XSA244. Keep PKGREVISION to 1 to account for the fact that it's
not a stock Xen 4.8.2.

Note that, unlike upstream, pv-linear-pt defaults to true, so that
NetBSD PV guests (including dom0) will continue to boot without changes
to boot.cfg

Log message:
Don't force enable ssp on xenkernel packages. fixes build

Log message:
Restrict -falign-functions to GCC.

Log message:

Log message:
adding patch for XSA-212 from upstream
(http://xenbits.xen.org/xsa/advisory-212.html)

Log message:
Add xenkerne48 and xentools48, version 4.8.0.
This includes stub domains support, but it should be considered
experimental at this time. Stub domains hangs with serial ports,
or more more than one virual disk (multiple virtual ethernet have not been
tested).
