glib2: update to 2.65.0

Modified to use meson as upstream has abandoned autotools.

Added license information.

Cleaned up Makefile for consistency between packages.

Added hack to compile static libs.

Removed old patches and add new ones.

Removed BUILD_PARALLEL options. These are default with ninja/meson.

Removed gettext build dependencies. glib2 now includes its own solution.

Added patch to remove distutils host dependency.
