gstreamer & gst-plugins: --HEAD

Building from gstreamer master is required for development
purpose.

Also gest-plugins-* and gst-libav get --HEAD.

gobject-introspection: depends_on :python

To avoid ImportError: Symbol not found: _PyList_Check
during build.
gst-plugins-base: --with-gobject-introspection

should propagate to gstreamer otherwise build will fail.
xmto: fix missing DTD/entities errors

`xmlto` forces the `--nonet` flag on `xsltproc`, which means it throws up an
I/O error whenever it needs to hit the network to pull down any files. So we
patch out the forced flag, and additionally add `docbook-xsl` as a dependency,
which'll reduce the odds of having to hit the network in the first place.

Fixes #21040.

openssl: run "make depend" to recompute header dependencies

Fixes #21895.
PythonInstalled: Unset PYTHONPATH for `satisfied?`

When a formula `depends_on :python` *and* `depends_on :python3`
the `modify_build_environment` method sets the PYTHONPATH
and the Python 3.x requirement then fails because it finds
the sitecustomize.py from Python 2.x in the PYTHONPATH.
Remove ad-hoc header padding fixes

This is the default now.

qemu 1.6.0: add vde networking support

The VDE (Virtual Distributed Ethernet) networking model is
useful for QEMU, as it allows muliple QEMU instances to connect
to virtual networks. More interesting is that a VDE server such
as vde_switch can connect a VDE network to the host machines
network, letting all QEMU instances on the virtual network
connect over the host's network.

This change adds support for VDE networking in QEMU by
using the vde project.
