The RedChannel argument is not used by pipe_item_init. Removing it
will make code simpler in places where we don't have a RedChannel
directly available.
This is acting on a PipeItem object so correct name is pipe_item_init.

Commit e9ed125d introduced a dead-lock regression by taking twice the
same lock recursively. The previous code checked if a dmabuf was set
without taking the lock, for queuing scanout messages. Since the message
is being processed later on, it make sense to queue and delay until it
is sent to check if there is a scanout.

Considering that:
- QXLState is the state of QXLInstance implementation;
- RedDispatcher is the implementation of QXL;
- qif (QXLInterface*) field can be computed really easy from QXLInstance;
- most of its state is private.
Make all structure private and use QXLState instead of RedDispatcher.

Rules are now:
Compression type:
off -> uncompressed
quic -> jpeg if possible else quic else off
lz -> lz if possible else off
glz -> glz if possible else lz else off
auto_lz -> lz if possible else jpeg else quic else off
auto_glz -> glz if possible else lz else jpeg else quic else off
lz4 -> lz4 if possible else lz else off
jpeg is used only when jpeg-wan-compression allows it

Create an async, and marshall the GL_DRAW message. Count number of

The count is going to be updated in the following patch when the client

This commit reworks a bit the management of RedCompressBuf so that
compress_buf_new/compress_buf_free become unneeded.
Since d25d6ca0 and the introduction of encoder_data_reset,
compress_buf_free is already unused outside of dcc-encoders.c and could
be static. This in turn makes compress_buf_new a bit odd as the matching
destructor is never used in dcc.c.
This commit introduces an encoder_data_init() method which is hiding
the initialization of the EncoderData structure from the dcc.c code,
allowing to get rid of compress_buf_new() calls from dcc.c code.
It also uses this as an opportunity to stop using GSlice for
RedCompressBuf.

For zlib+glz compression image if first compressed with glz then the
resulting buffer is compressed again with zlib then the buffer from
zlib is returned to the caller.
However the temporary glz buffer was not freed resulting in a memory
leak.
