[PATCH 0/2] add flags for conditional compilation of qemu dependencies

[Carlo Marcelo Arenas Belon]

This series adds options to kvm's configure that match the ones used by qemu
to conditionally enable or disable options that alter its runtime dependencies
and functionality, like for example, support for alsa or TLS encrypted vnc
sessions.

[PATCH 1/2] alsa configure option

[Carlo Marcelo Arenas Belon]

Add an --enable-alsa option to conditionally add support for alsa so that
QEMU_AUDIO_DRV=alsa is supported.

This makes the dependency to alsa conditional and explicit.

[PATCH 2/2] vnc-tls configure flag

[Carlo Marcelo Arenas Belon]

Add a --disable-vnc-tls option so that support for TLS authentication
for the VNC server can be conditionally disabled.

This makes the dependency to gnutls added by the new qemu conditional and
explicit.

Applied both, thanks.  But if someone is thinking of a patch flood to
add all qemu options, I'd prefer a passthrough instead.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

The only other option I was interested in implementing was the one to
conditionally enable or disable support for sdl, but I can see why a
passthrough is a better option in the long run.
