* before having possibility to set VGA from outside,
it was set to 0x8 (=16.3 dB) for manual, but
it was set to 0xb (=26.5 dB) for automatic (LNA/Mixer) gain.
erroneously it was initialized to 0x0 in r82xx_init_array[]
* also fixed parsing/processing of ifm value
* might fix https://github.com/librtlsdr/librtlsdr/issues/81

* bugfix wrong return value in r82xx_set_pll(),
when "PLL not locked" was printed.
removed all similar messages - regarded as noise,
e.g. when running rtl_test -t
* suppress output of tuning band 0 - 0 Hz in rtl_test

This scans 0 - 3GHz looking for frequencies that can be tuned to without
error, and refines the band edges further once a tuneable band is found. It
should work with any tuner that correctly reports tuning errors. It takes
about 1.5 minutes to complete on a R820T.

If the librtlsdr code comes from a tarball, it doesn't have any .git/
metadata, and therefore even if Git (as a tool) is found, the logic in
cmake/Modules/Version.cmake fails finding a version through Git:
-- Extracting version information from git describe...
fatal: Not a git repository (or any of the parent directories): .git
As a consequence, the VERSION variable is empty, which later causes
cmake to bail out with:
CMake Error at /home/test/autobuild/run/instance-1/output-1/host/share/cmake-3.15/Modules/WriteBasicConfigVersionFile.cmake:43 (message):
No VERSION specified for WRITE_BASIC_CONFIG_VERSION_FILE()
Call Stack (most recent call first):
/home/test/autobuild/run/instance-1/output-1/host/share/cmake-3.15/Modules/CMakePackageConfigHelpers.cmake:225 (write_basic_config_version_file)
CMakeLists.txt:173 (write_basic_package_version_file)
To avoid this, we only use Git to determine the version if the cmake
project top-level source directory has a .git/ folder.

This is an import of the rtl_biast command line tool from the
rtlsdrblog github repository. It's easier to include it here than
try to package up the separate application because they both
wish to install dynamic libraries.

rtl_biast allows for non-default GPIO pins to be used.
Add an API call which allows for that.

librtlsdr uses two fileds of struct rtlsdr_dev to communicate
between threads. On hardware with weak memory model it is not
guaranteed that it will work, as C memory model guarantees
nothing for simple variables.
Using C11 atomics seems to be overkill here, but async_status
and async_cancel better be marked as "volatile".
