The pointer was initially added to support to open a lchan
by using the gsm_subscriber structure. We would have restored
the struct gsm_bts from the db when loading the subscriber.
Instead we will dynamically resolve the gsm_bts and might end
up paging multiple bts in the same (stored/old) location area
until it answers.

subscr_get_by_tmsi might log as well and then the order of
debugging it not as clear as it could be.

It will define -DVTY_CRYPT_PW= if crypt is found. If -lcrypt is
needed, $(LIB_CRYPT) will be -lcrypt.
Compiles on OS X and Linux and reenables crypt.

Tells mISDN not to release layer 2 on closing socket, when not
requested. If mISDN was told to release layer 2 once, it will continue
to release layer 2 on every shutdown of OpenBSC.

During bootstrap of BS11, the e1links are initialized. This must also be
done when BS11 is already bootstrapped (when restarting OpenBSC). It is
required to correctly multiplex the audio traffic between channels.
Without it, all time slots refer to card 0, slot 0, subslot 0, which
causes crashes when handling TRAU frames..

Some debug outputs now correctly use end-of-line characters.

Release the channel when it is not used, otherwise claim it
is still in use...

This patch will fix subscriber usage countinig.
It may happen, that the subscriber count will not be 0 after releasing
of a call. (This problem is solved with the application patch (27),
which will replace static call transaction by a dynamic transaction
list, and use subscriber for each transaction created.)

Log changes of the use count of a gsm_subscriber.

This is coming from patch 16 and is one of the two changes. When
invoking subscr_update update the lac entry as well.
|

Now MM can be specified on the command line with the debug option.

A new function trau_recv_lchan() is used to link a channel to a call reference
of a transaction. (Transactions are used in later patches.) TRAU frames will
then be forwarded to the application with the given call reference (in later
patches). Also the application can send TRAU frames by using trau_send_lchan().
A new list is introduced in trau_mux.c. (upqueue_entry) All subslots
that must be sent to application are listed here.
Received TRAU frames are written in the upqueue of application
interface, if a call reference is found in the upqueue-list. If an entry
is found the ss_entry list, the TRAU frames are bridged as before. The
frames have a message type (msg_type), a call reference (callref) and a
trau frame (data). The length of trau frame is defined by the content of
the c-bits inside the frame.
There is no support for ip.access yet, as they don't use the traditional
TRAU frame format. Harald must add this in order to use application interface
with ip-access. The bridging with ip-access works as before.

Control. This is required for later patches, that extract the call
control from gsm_04_08.c. (Andreas Eversberg)

no IE type included in the message. These information elements are
mandatory, so their actual IE type is known. The improved parse_tlv()
function allows to parse zero, one, or two length-value elements.

is used for the E1's time slot. This timer replaces the "usleep()"
function, so the process will not block the execution of libbsc. The
timer is started after a frame is transmitted. If another frame is in
the transmit queue, the frame will only be queued until the timer times
out. If the timer is not running or times out, the frame is transmitted
and the timer is restarted.
The problem with partly provisioned TRX (locks show on LMT) is solved.
The adjustment for the inter frame delay of 50 miliseconds is for
further study.

select function ob libbsc. A "polling" flag is used to enable polling.
In this case select() will not sleep until file descriptor events occurr
or nearest timer expires. Also a return value will indicate if there was
an event that has been handled. If there was an event, the application
decides to poll again and don't wait.
In case for bsc_hack, the polling flag is not set. select will sleep as
usual.

The problem in the old logic was that we started talking to a given object
(e.g. radio carrier) one we received an administrative state change report. It
turns out we have to wait for the software activation report instead - and
everything suddenly works.
