2.1.0
From: Andrei Emeltchenko <[email protected]>
avdtp_new() is refactored to two functions avdtp_new() and
avdtp_set_control() similar to set avdtp_set_transport(). This is needed
for code which creates avdtp session without fd like inside sink, source
and transport code.

disconnect timer code setup streams instead of disconnecting as it
mentioned in the related comment. That does not look very right thing to
do in this situation and this is not used in android code. Removing it
simplifies avdtp code a lot and makes it easily to merge with android
code base.

I find out that bluez a2dp also do not work fine in case of multiple
vendor codecs in remote. So I think bluez also needs this android bluez
patch.
Originally I consider to use check_vendor(profile/audio/a2dp.c)function
from avdtp_find_remote_sep. but it does not seem good to me.
Could you give us the guidance?
Thanks

We will be migrating to use android implementation, which btw has unit
tests, but yes without this patch vendor codecs might not work if the
codecs don't match.

Could you give us the guidance?
Thanks
