Use POLLIN on the socket instead, the b-channel should be able
to write when there is something to read.
Several other projects handle it this way, e.g. libosmo-abis.

The code was improperly using peer_data as an indicator that the sigbridge
ss7 mode was enabled. The channel flag FTDM_CHANNEL_NATIVE_SIGBRDIGE should
be used instead
- The outgoing tdm leg should not move to UP until
after the IAM is sent at the end of the function
- The UP state should be processed immediately otherwise
the state processor is not run due to the way the main
ss7 processing loop currently works
Use FTDM_SIZE_FMT where needed, don't treat ftdm_event_t as an int
(even if the e_type enum is the first member), datalen vs. *datalen fix
and other warnings.
All reported by __check_printf() (GCC + __attribute__((format(printf,x,y))) ).

For compilers that seem to do the wrong thing(tm).
Speculative fix for:

Only two mISDN hardware drivers emit MPH_INFORMATION_IND messages and both use a different payload:
- hfcsusb (HFC-based USB dongle) sends a set of ph_info + ph_info_ch structures
which contain the complete state information of the port
(including internal hw-specific state and flags).
- hfcmulti which sends a single integer, a single L1_SIGNAL_* event.
We now try to guess the type of message from the payload length.
The hfcmulti signals are converted to FreeTDM alarm flags; the hfcsusb
state/flags are defined in kernel internal hw-specific headers and are ignored ATM (todo).

Add MISDN_MSG_DATA() helper macro for easy access to mISDN message
payload.
Add forward declaration of misdn_handle_mph_information_ind() and use
it in misdn_activate_channel().

Add missing mISDN event/message types (e.g. MPH_INFORMATION_IND)
and use a helper macro (MISDN_EVENT_TYPE) to define the entries,
like we already do for misdn_control_types[].
