6cffabd09d v4l2: don't mmap when the buffer has data already 
When the buffer has data (but no fd), don't mmap the buffer but simply
use the data pointer directly.

This makes v4l2 work with inlined buffer memory.

7631316186 buffer: add option to reverse filter priority 
By default, buffer negotiation favours the default property values of
the output node. Make this configurable and reverse this logic when the
output is a driver.

This makes it so that a stream connecting to a source will negotiate
with the preferences of the stream and not the source.

An example is a stream that wants 4 buffers from v4l2-source, because
v4l2-source has a default of 4 buffers, this will always result in 4
buffers, ignoring the preference of the stream.

ccf2891070 v4l2: fix buffer amount check 
When we get buffers from the driver, check if we have at least as many
as we requested. If we have more, that's ok, we will simply not queue
them.

Previously we would ignore the input number of buffers and use the
allocated amount to fill up the buffer array, which might be too small
and then we crash.

44d743ed95 spa: make all format parsing fields optional 
Just like the optional build, make all field parsing optional. This
will leave the fields with their default values if they are not parsed
from the param.

We can then remove our custom functions and use the generic ones in
various places.

motherboards) can detect the presence on all I/O jacks.

If user connects only speakers, it's a valid case.

e6fd5888ee param: add a new user seq field in the param-info 
Add a new seq field in the param-info struct. Users can use this
field to keep track of pending param updates.

Store the latest seq number of the param update in the seq field. Remove
all params that don't match the sequence number because they are too
old. This avoids duplicate old params in pw-dump output.

Rework the pulseaudio manager with this same method.
