This patch resolves the following issue:
In function 'memset',
inlined from 'bargraph.constprop.14' at gsm322.c:325:8:
/usr/include/bits/string3.h:81:30: warning: call to '__warn_memset_zero_len' declared with attribute warning: memset used with constant zero length parameter; this could be due to transposed parameters [enabled by default]
1. "no neighbor-measurement idle": neighbor cell measurement for cell
re-selection
2. "no neighbor-measurement dedicated": neighbor cell measurement for
handover
The initial cell channel decription is received via SI1. During a call this
description may change due to handover, assignment, frequency redefinition.
Whenever it changes, the last received cell channel description is used to
handle messages that do not include this information element.
Example of one call with handover inbetween. The assignments do not include
a cell channel description:
IMMEDIATE ASSIGNMENT: Use cell channel description from SI1.
ASSIGNMENT COMMAND: Re-use cell channel description from SI1.
HANDOVER COMMAND: Use new cell channel description from HANDOVER COMMAND.
ASSIGNMENT COMMAND: Re-use cell channel description from HANDOVER COMMAND.
sel_si structure tracks content of SI5* and SI6 messages. The informations
will change after handover, so they do not refer to the origin cell.
The list of scanned cells is not affected. The sel_si structure will be
overwritten with the selected cell after leaving dedicated mode.
The handover is forced by reporting perfect measurement results of a given
neighbor cell. All other neighbor cells and the serving cell is reported as
poor. The falke report will sustain until the connection is released or a
new 'better' cell is specified.
When establishing dedicate mode, a flag is used to disable transitter.
When transmitter is disabled, access bursts are allowed.
After sending a L1CTL_PARAM_REQ, the transmitter is enabled with given
parameters.
* Flag to enter dedicated mode with TX disabled
* Flag to use sync info of neighbor cell
* Flag to use sync info of previous serving cell
* Index of neighbor cell
All these parameters are required to handover to a new channel.
When TPU offset must be changed (assignment to different timeslot or handover
to a different cell), all tasks will be disabled until new TPU offset has been
applied. Currently scheduled tasks are finished before the new TPU offset is
applied.
On change of TPU offset, the TPU's interrupt may skip one frame when changing
backwards in time. Also it may generate two interrupts when changing
significantly forward in time. This is compensated by changing the GSM time.
The returned value of trans_assign_trans_id() must be stored into a
'int' rather than uint8_t to allow proper testing of negative return
values (errors).

Bugfix in Osmoload.c: Assigning correct value to data pointer in
LOADER_MEM_READ. Wrong value was introduced in last update when
msgb_get() was replaced by msgb_pull() which returns end of data instead
of start of data.
If "clip" is given at vty, CLIR must be suppressed, which results in
presentation of caller ID digits, even if suppressed by network.
If "clir" is given at vty, CLIR must be invoked, which results in
restriction of caller ID digits, even if not suppressed by network.
Note: This only work for outgoing caller ID. Incomming caller ID
restriction cannot be suppressed.
Some MDL-ERROR causes must not lead to link failure. The missing
"return 0" causes all errors to be ignored which are not listed inside
switch/case statement.
The downlink singalling failure counter DSC is decremented by 4
in case of unsuccessfull decoding of CCCH block and incremented
by 1 in case of successfull decoding of CCCH block. The initial
and maximum value of 90 requires to check the signal only once
per 51 multiframe.
If DRX would be supported, only a subset of 51 multiframes are
received, so the initial / maximum value of 90 must be reduced
accordingly.
If mobile phone has started, it is reset after shutdown. This
ensures that the phone is not transmitting anymore, especially
while shutting down in dedicated mode.
Using CTRL+c:
The first signal causes initiating of shutdown with detach
procedure. The second signal causes initiating of shutdown
without detach procedure. The third signal will exit process
immidiately. (in case it hangs)
Using CTRL+z:
The first signal causes initiating of shutdown without detach
procedure. A subsequent CTRL+c would exit process immidiately.
Since we now initialize the display for all apps, it
otherwise just shows the last content of the display
ram, which is weird.

So far the loader-app used to do the init on its
own, which brought a lot of problems for board-
specific initialization.

Operation in GSM850 band requires IQ swap because of the offset PLL
used in the TRF causing spectrum reversal.
