Only the first EIR data structure from the LE advertising report
event is dumped. This patch fix this, so all EIR data structure
present in that event is dumped.
Adds support for parsing extended control field. Extended control field
may be used for ERTM and streaming mode (if EWS specified). ext_ctrl
flag resides in cid table. This also fixes P-bit decoding.
If packet_type is not START or SINGLE, we have to continue where we
stopped from previous packet. Therefore we must store where we left on
previous packet due to packet size limit. We store both the number of
attributes missing and the lenght of the last attribute that is missing.
An example interaction for this implementation, obtained with PTS test
TC_TG_MDI_BV_04_C (I reduced the MTU in order to reproduce it here and
values between brackets I added now):

If multiple ACL connections are using identical cid values, the L2CAP
parser will match the first avail cid found in the cid table. This
error often leads to incorrect psm determination, and thus incorrect
parsing of higher-layer frames.
When searching the cid table, a matching cid value must match by
ACL handle as well.
