0679c76b64 vp8enc: Set VP8E_SET_CPUUSED to 0 
This setting controls how much CPU can be used by the encoder, specified
in fractions of 16. Negative values mean strict enforcement of this
while positive values are adaptive.

The default value is -4, which means that we're not running as fast
as possible and probably are wasting some quality. 0 is the recommended
default by libvpx upstream.

c2809e6843 vp8enc: Use VPX defines for REALTIME, GOOD/BEST quality deadlines instead of our own 
These are the values used for the speed property.

7ce969720f vp8enc: threads property 
Increasing from 1 to 2 threads on an Thinkpad X60s decreased encode time
in a test from ~24 s to ~19 s, so this is quite useful.

Ideally we should let 0 be the default and automatically match the number
of CPU cores (or something).

17ab21dae3 vp8enc: add mode property to switch between CBR/VBR 
Always using CBR when bitrate is used isn't that great, VBR mode
can produce meaningful results too.

54e6f65ef3 vp8: move #ifdef HAVE_VP8_ENCODER/DECODER 
Otherwise we'll try including e.g. <vpx/vp8cx.h> which doesn't exist.

d3c9d84fdf vp8: Only enable the encoder or decoder if it's available in libvpx

e428c10605 vp8: exlcude dec/enc based on CONFIG_VP8_DECODER/ENCODER 
This may not be very autotoolish, but works with libvpx in the state
that libvpx is actually in. Moved the debug init to the elements
themselves to minimize amount of #ifdefs

2f4ea3b734 vp8enc: Limit max-latency to 25 to match libvpx 
From libvpx/vp8/encoder/onyx_int.h:
 #define MAX_LAG_BUFFERS (CONFIG_REALTIME_ONLY? 1 : 25)

While we don't need to be tied to what libvpx does internally, it
doesn't make sense to pretend to support longer frame lags than are
actually possible.

fd77b419a4 vp8: Undef HAVE_CONFIG_H before including libvpx headers 
A public libvpx header includes private headers if this is
defined, causing compilation failures because the private headers
are not installed of course.
