In change [1] together with the actual implementation I introduced
a serious bug to trx_sched_fn(): if a timeslot is configured to use
frequency hopping, both 'pinst' and 'l1h' pointers are *overwriten*
in the inner loop, so the Downlink burst is re-directed to the
approproate PHY instance. However, if a subsequent timeslot is not
hopping, the Downlink burst would be re-directed to the wrong PHY
instance because both pointers were overwriten during a previous
iteration.
Let's add another 'struct phy_instance' pointer to the inner loop,
so it's properly re-initialized for each timeslot iteration.

New channel mode values have recently been added with change [1]
to 'enum gsm48_chan_mode'. The lack of default branch in
lchan2lch_par() caused build failures on Jenkins:
oml.c:956:2: error: enumeration value ‘GSM48_CMODE_SPEECH_V2_VAMOS’
not handled in switch [-Werror=switch]
oml.c:956:2: error: enumeration value ‘GSM48_CMODE_SPEECH_V3_VAMOS’
not handled in switch [-Werror=switch]
oml.c:956:2: error: enumeration value ‘GSM48_CMODE_SPEECH_V5_VAMOS’
not handled in switch [-Werror=switch]
This function is duplicated in osmo-bts-{lc15,oc2g,octphy,sysmo},
so we unfortunately need to apply the same fix to all copy-pasted files.

The check in lchan_ms_ta_ctrl() breaks Timing Advance control on
SDCCH channels, because 'num_ul_meas' wraps and never reaches 4.
Neither this check makes any sense for other channel types,
because lchan_ms_ta_ctrl() is always called in the end of the
measurement period. Let's drop it.

In any case, every test relying on logging output validation should
always explicitly state the config to avoid issues in the future if

use those structs to get rid of all the manual decoding of l1_info.

So far, the only way to configure GSMTAP Um logging is to use the
cmdline argument '-i'. Let's deprecate it, and add a VTY command
to allow setting the remote host from configuration file.
The legacy '-i' option, if provided, overrides the configuration
file option, and will also appear in 'write file'.

The cfg_out macro is used like a function in the code below its
definition. This means a colon will follow after it is used. When
the vty_out call in the macro already has a colon the final result will
be vty_out(...);;. This works fine as long the macro is not used in one
line if/else if/else constructs without curly braces {}. The compiler
will interpret the double colon as two lines of code and run into an
error then. Lets fix this by removing the colon from the vty_cout in the
macro.

The only reason why it was not 'const' is that in lchan_new_ul_meas()
we may need to overwrite 'ulm->is_sub'. This can still be done after
memcpy()ing a new set of samples to the destination buffer.

At the beginning of repeated_ul_sacch_active_decision() The UL-SACCH
repetition capability is tested. If no UL-SACCH repetition is enabled
the function exits. However, we should also make sure that the struct
member that enabled UL-SACCH repetition on the lower level is set to
false as well. Normally that should be the case because it was never
set to true before, but it is better to be sure.

The function checks meas_res->rxqual_sub against the lower threshold
value in order to decide when to turn FACCH repetition off. This is not
correct. It should compare against rxqual instead.

A channel activation for handover to another cell does not know the
Timing Advance until the handover RACH is received. It does not make
much sense to enable downlink SACCH without an accurate TA.
If the BSC omits the Access Delay IE (a.k.a. the Timing Advance), do not
enable downlink SACCH. This is expected to happen only for inter-cell
handover. In all other situations, the TA should be known either from a
Channel Request RACH for Immediate Assignment, or from the previous
lchan on the same cell upon Assignment / intra-cell handover.

One part of the algorithm simply provides a _suggested_ 'delta' that
needs to be applied to the current power level, while the other part
ensures that this suggested value does not exceed the limits. Thus
it's possible that some logging messages would state that the power
reduction value remains unchanged, while the 'detla' != 0.
