This way the video encoder is not forced to use malloc()/free().
This also allows more flexibility in how the video encoder manages the
buffer which allows for a zero-copy implementation in both video
encoders.

The Spice server administrator can specify the encoder and codec
preferences to optimize for CPU or bandwidth usage. Preferences are
described in a semi-colon separated list of encoder:codec pairs.
The server has a default preference list which can explicitly be
selected by specifying 'auto'.

encode_frame() needs the QXL_DRAW_COPY operation's SpiceCopy.src_area
field anyway, so the width and height parameters were redundant.

Video frames correspond to QXL_DRAW_COPY operations where the frame area
is defined by the SpiceCopy.src_area field.

This replaces the original mjpeg_encoder API with a VideoEncoder base
class which can be reimplemented by other encoders.
This also renames the members and enums from mjpeg_* to video_*.

It has the same lifetime as the corresponding structure so this
simplifies keeping track of it.

This is a generic function not tied to the red_xxx functionality and the
new name clarifies that it returns the time in nanoseconds (unlike
g_get_monotonic_time()).

Note that if frame_size == bytes_per_sec == 0 this now returns
MJPEG_MAX_FPS but this should not happen anyway.
