According to gettimeofday manual:
"Applications should use the clock_gettime() function instead of the
obsolescent gettimeofday() function."
Furthermore, it may be desirable in the future to use other clocks such
as monotonic.

Allow selecting a specific LimeSDR device by setting dev-args in the
config file. Split up the given dev-args address by comma and select
the device where all substrings can be found.
I could not test this with real hardware, but I have added a test case
to make sure this works as expected.

This log category is applied to messages related to TRX CTRL socket
interface, and it's printed in yellow, same color used in osmo-bts-trx
for TRX category (so same messages are printed with same color in both
sides).

Original issue: In order to use SSE instructions, 16-byte aligned memory
chunks are needed, and C++ version < C++11 doesn't provide for a native
new/delete store. For that reason, memalign() must be used in the
implementation of convolve_h_alloc() for some buffers.
On the other side, The C++ code relies on C++ "new T[]" operator to
allocate a chunk of memory containing an array of class instances. As
classes are complex types, they cannot be allocated through C structures
(calling malloc). Experimentally can be seen too that it's unreliable
and the process will crash during startup if malloc() is used and then a
Complex<> deferred from it.
Previous implementation allowed for use of convolve_h_alloc or new[]
based on how the (signal)Vector is called, because then the buffer is
not going to be managed internally. But that's unreliable since resize()
calling resize() on it could use "delete" operator on a malloc'ed
buffer, and end up having a new new[] allocated buffer. It was also
found that some of the callers were actually leaking memory through ASan (because the
buffer is not managed by the Vector instance).
IMHO best option would be to rewrite all this code using C structures
and malloc/free exclusively, since it would make all this cod eeasier to
maintain.
But for now, let's extend the Vector class to allow specifying an
external alloc/free function and let the Vector instance take care of
the ownership of the buffer in all scenarios.

Add new environment variables WITH_MANUALS and PUBLISH to control if
the manuals should be built and uploaded. Describe all environment vars
on top of the file.
When WITH_MANUALS is set, install osmo-gsm-manuals like any other
dependency and add --enable-manuals to the configure flags (for "make"
and "make distcheck"). Add the bin subdir of the installed files to
PATH, so osmo-gsm-manuals-check-depends can be used by ./configure.

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.

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.

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.

Now incorporate in the build system.
Build with:
$ autoreconf -fi
$ ./configure --enable-manuals
$ make
Shared files from osmo-gsm-manuals.git are found automatically if
- the repository is checked out in ../osmo-gsm-manuals; or
- if it osmo-gsm-manuals was installed with "make install"; or
- OSMO_GSM_MANUALS_DIR is set.

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.
