The second loop in osmo_revbytebits_buf() in src/bits.c grabs
4 bytes each iteration, which can easily go past the supplied
input in some cases.
Compiled with -fstack-protector , I get a "stack smashing detected"
in the bits test.

This file is created in ./configure so we shouldn't remove it with make.
Otherwise ./configure && make clean && make check fails with:

Stop.

This was found while implementing handover on a sysmobts. When we
receive a channel release request for a channel that was never really
activated (set_lapdm_context() was not called) we segfault in
lapd_recv_dlsap().
We now return early with -EINVAL in rslms_rx_rll() if we receive a
message that assumes set_lapdm_context() was already called.
These are:
* RSL_MT_UNIT_DATA_REQ
* RSL_MT_DATA_REQ
* RSL_MT_SUSP_REQ
* RSL_MT_REL_REQ
A test case was added to trigger the issue.
GCC 4.7.2 was already smart enough to see that the table is const
so there is no change in the generated assembly code. For some reason
the dispatch is still going through one relocation.
When OpenBSC is handling more than one message at a time it is difficult
to see which log message belongs to which SMR instance. Introduce a
uint64_t id that can be set to the row_id/message_id and prefix all
log messages with SMR(ID).
This change is ABI and API incompatible with previous versions of
libosmogsm.

msgb_pull returns a pointer to the new begin of the
buffer, unlike msgb_get(), where those functions
were originally taken from.

When the connection may not released print the name of the current
state to ease with debugging and verification that this is not a
valid state transition.
The bits test will fail on Debian Stable for x86. Somehow the load
of a static const array is ending up accessing random memory. This
only happens when not using any -OX options and this is caused by
us. Do not override the default debian CFLAGS.. and the tests will
pass on debian stable.
Use FreeBSD struct iphdr definition for OSX also. From the commentary in
the source file:
On BSD the IPv4 struct is called struct ip and instead of iXX
the members are called ip_XX. One could change this code to use
struct ip but that would require to define _BSD_SOURCE and that
might have other complications. Instead make sure struct iphdr
is present on FreeBSD.
Prior to this fix, a persistent file or syslog log configuration
didn't work across an application re-start, as the
"logging filter all 1" was never saved and thus no messages were
logged.
* Disable color and printing the filename of the stderr log target,
update the results
* Add the .ok, .err and .sh files to the extra_dist
* Execute the shell script from the source directory
Introduce a print_filename attribute for each logtarget. Initialize it
with 1 to be backward compatible with earlier versions. The bit is taken
from an existint bitfield. There were at least six bits left of the byte.
