Both MO and MT SMS are supported.
Transmission an reception can be controlled via VTY:
en
sms 1 <destination> <text>
All received SMS are stored in "~/.osmocom/bb/sms.txt".
SMS transmission is performed on SAPI 3 datalink, using DCCH or ACCH.

RR now handles SAPI 3 datalink.
MM connections now have and individual sapi, so MM can use right SAPI
for communication with other layers, as well as releasing the right
MM connections in case of link release.

In case we got paged with IMSI, but even if we have a valid TMSI, we need to
respond with IMSI, because the network may not know our TMSI anymore.

If location updating (attachment) fails, the mobile returnes into idle
state. Because the SIM may be valid in this location area, the mobile must
check if the SIM is already attached. If not it may not change to normal
service.

When mobile exits, a list of allocated memory chunks are dumped to
stderr. This helps to find talloc_free / msgb_free leaks.
During process, a SIGUSR1 or SIGUSR2 can be used to dump currently
allocated memory chunks.

The SMR process is used to transfer SMS TPDUs. It is now extracted from
OpenBSC. It includes a real state machine now for easier debugging.
Also it implements the TR1M and TR2M timers. The memory notification
procedure is missing, but not required for network side.

Furthermore, notice that the initial checks:
if (!node->rb_left)
child = node->rb_right;
else if (!node->rb_right)
child = node->rb_left;
else
{
...
}
guarantee that old->rb_right is set in the final else branch, therefore
we can omit checking that again.

There are two cases when a node, having 2 childs, is erased:
'normal case': the successor is not the right-hand-child of the node to be erased
'special case': the successor is the right-hand child of the node to be erased
Here some ascii-art, with following symbols (referring to the code):
O: node to be deleted
N: the successor of O
P: parent of N
C: child of N
L: some other node
normal case:
O N
/ \ / \
/ \ / \
L \ L \
/ \ P ----> / \ P
/ \ / \
/ /
N C
\ / \
\
C
/ \
special case:
O|P N
/ \ / \
/ \ / \
L \ L \
/ \ N ----> / C
\ / \
\
C
/ \
Notice that for the special case we don't have to reconnect C to N.

Tfour 4 redundant if-conditions in function __rb_erase_color() in
lib/rbtree.c are removed.
In pseudo-source-code, the structure of the code is as follows:
if ((!A || B) && (!C || D)) {
.
.
.
} else {
if (!C || D) {//if this is true, it implies: (A == true) && (B == false)
if (A) {//hence this always evaluates to 'true'...
.
}
.
//at this point, C always becomes true, because of:
__rb_rotate_right/left();
//and:
other = parent->rb_right/left;
}
.
.
if (C) {//...and this too !
.
}

The 'rb_first()', 'rb_last()', 'rb_next()' and 'rb_prev()' calls
take a pointer to an RB node or RB root. They do not change the
pointed objects, so add a 'const' qualifier in order to make life
of the users of these functions easier.
Indeed, if I have my own constant pointer &const struct my_type *p,
and I call 'rb_next(&p->rb)', I get a GCC warning:
warning: passing argument 1 of ?~@~Xrb_next?~@~Y discards qualifiers from pointer target type

alloca.h is not available on FreeBSD, use the default autoconf
function to check for it, there is a complete list[1] of what to
do for using alloca but let us see how far we get with this test.
Include netinet/in.h for the IPv4 and IPv6 socket address. Check
for dlopen in libraries and use this instead of linking -dl.

We alias the uint8_t buf[..] to a uint16_t* which is violating
the aliases rule of C. Use an explicit memcpy to copy the first
two byte of the buffer. GCC 4.6.2 (debian) is clever enough to
use a normal load does not generate a memcpy call.
osmocon.c: In function ‘un_tool_read’:
osmocon.c:1239:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
With the new generated headers for the CRC code, we need to include
the builddir as well in case we're building out of tree.
