This change fixes lots of memory leaks inside libLimeSuite as
announced by ASan after exiting the osmo-trx process (throgh
CTRL+C for instance).
This way also we make sure libLimeSuite can communicate with the HW and
close whatever subsystems were enabled during LMS_Open time.

Set AM_DISTCHECK_CONFIGURE_FLAGS in Makefile.am instead of
DISTCHECK_CONFIGURE_FLAGS. This is the recommended way from the
automake manual, as otherwise the flag can't be changed by the user
anymore.

Found by ASan. when PointerFIFO::release() is called, alloicated node
being released is actually stored into an internal list for later-reuse
without having to access memory allocator. However, nodes from this
list are never freed.

They are recreated during start(). Actually, if they are not stopped
here, during start() after stop(), LMS_SetupStream() will fail because
it will detect the streams are already opened.

So far, the Rx gain was set to 34 dB, wile the comment stated it
would be set to half-point, which is 73/2=36dB. Let's adjust the
code to match the comment.
Change-Id: Idc646def53b83faf4e6c011fb595fa436e223b32
Due to (I believe) a copy+paste mistake from the USRP1 code,
we were using only a scale range of up to 9830 when transmitting
samples, rather than the full 16 bit signed integer range up to
32767.
As a result, we were loosing almost two bits (MSBs) of resolution
as well as a lot of transmit power.
This changes the scale factor to 0.707 (1/sqrt(2)).
Please note that the much higher DAC output level means that the analog
gain should be reduced. The theoretic range of up to 73dB should not
be used, but Lime Microsystems suggest a value of 61..67 dB. This can
be achieved by using a "osmotrx tx-attenuation" value of 6..12 inside
the osmo-bts-trx configuration file.

This chapter defines the protocol used between osmo-trx and
osmo-bts-trx.
Most of the text comes originally from osmo-trx.git/README, as it's the
only known documentation of the protocol other than the code itself.

When using multi-arfcn feature, several logical channels (arfcn) are multiplxed
into one physical transceiver, as can be seen in
uhd_device::set_channels.
As a result, when multi-arfcn is enabled some properties are actually
shared for those logical channels, and internally mapped to the first
(only existing) channel, and per-channel internal array variables are allocated
accordingly (size() == 1).
When setting RxGain, we need to set the correct existing physical
channel. Same check is done in getRxGain, and then we apply the RxGain correctly and
we avoid outputing an error "Requested non-existent channel" immediatelly after.

This is a preparatory change that enables a possibility to choose
the amount of synch. sequences to be used for Access Burst (RACH)
detection. The VTY flag will be introduced in further changes.
There are two correlation types now:
- RACH (default) - TS0 only;
- EXT_RACH - all TS0, TS1, and TS2 together.

According to 3GPP TS 05.02, section 5.2.7, there are three
synch. sequences for Access Bursts:
- TS0: GSM, GMSK (default),
- TS1: EGPRS, 8-PSK,
- TS2: EGPRS, GMSK.
Let's prepare everythyng to be able to detect all TS0-3 synch.
sequences, but keep detection of both TS1 and TS2 disabled
until the corresponding VTY option is introduced.

This way the dependencies are passed after the .la object, which seems
to be the correct order. Some setups may fail to find some symbols from
libosmocore otherwise (OBS i586).

osmo-trx can start a considerable amount of threads that can make
debugging it challenging at least. By using phtread_setname_np, the
system sets a meaningful name to the thread which can be seen while
debugging with gdb or by printing /proc/$pid/task/$tid/comm.
Now we also log system TID when setting the name so we can identify
different tasks in /proc even if pthread_setname_np fails.
