Add AVDTP SRC stream send buffer size verification

Functions get_send_buffer_size and set_send_buffer_size are added to
avdpt.c.

get_send_buffer_size returns size of send buffer for a given socket
on success or error code on failure. set_send_buffer_size sets size
of send buffer for a given socket, and returns 0 on success or error
code on failure.

Size of send buffer for L2CAP socket for SRC AVDTP stream is verified
during establishment of a new transport channel. If the size is less
than twice of outgoing L2CAP MTU, then it is considered as being
insufficient to handle streaming data reliably.

In this case buffer size is increased to be twice of MTU size. Such
fixes some IOP problems with car-kits that use large MTU for music
playback.
