This is the current status of the layer 3 protocols. Everything compiles,
radio ressource layer is partly complete. Everything is untested, so don't
expect that it runs and does something usefull. The next step for me is
running and debugging it.
Here is the list of files that are added / modified:

Added name to osmocom_ms structure.
l2_ctx is now named l23_ctx, because it is also used there.
A work-handler is usefull for applications that need to check queues.
The arfcn variable is renamed to test_arfcn.
I think that arfcn and other frequency parameters should be stored at
the process which sets it and using it when calling l1ctl_tx_ccch_req().
If file access is used to store network informations and user settings in the
/etc/ directory. Later it can be used to store them in the EEPROM of the
target.
bcch_scan first iterates over all GSM900/EGSM900/GSM1800 channels and
performs a power measurement. Based on this, it tries to look for
BCCH data on those ARFCNs. Currently, they are simply written to
the pcap file and not analyzed/processed in layer23 yet.
similar to the concept of having 'apps' in the firmware build process,
I'm now building the common code as liblayer23 and we have three apps
that use this library:
layer23 - the old layer23 program
bcch_scan - a passive bcch scanner under development
echo_test - a test program sending large msgb's containing zero bytes
* added missing param in call to gsm48_rx_bcch
* added 'extern' to declarations of rsl_rlm_cause_strs and target_board
* added several 'const' for strings
* removed useless 'bufptr,' from hexdump
(From: itsme <itsme@xs4all.nl>)
* introduce a new 'l1ctl_hdr' structure common to all messages
on this interface
* use struct l1ctl_hdr in both the firmware and layer23
* add a new L1CTL_PM_REQ request for performing layer23-initiated
power measurements (firmware does not implement them yet)
* remove linuxlist.h copy and use osmocore
* don't put 'struct gsm_time' into l1ctl packets
* include rx_level and snr for each burst in l1ctl
* properly build libosmocore.a for target
* move gsmtime functions into libosmocore
* move ctype.h to standard location
* use GSMTAP for uplink frames (generated by layer23; sent to L1)
* only use GSMTAP if the user specifies the '-i dstip' arguments
* properly encode the GSMTAP channel type
* requires GSMTAP protocol version 0x02 (see next commit for wireshark patch)
