Always pass -headerpad_max_install_names to the linker

We use install_name_tool pretty liberally, so we need to take steps to
ensure libraries and executables are always linked with this flag.

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.
