Eric Wild dadabeceaf cmake: actually make linking work 
Appending to lists from subdirs does not work as expected, so work
around that to allow collecting the necessary libs.

Clayton Smith 52fcb0935f A lot of Boost functionality is available in C++11. Since GNU Radio is moving away from Boost, it probably makes sense to do so in gr-osmosdr as well. 
This change removes all usage of boost::mutex,
boost::mutex::scoped_lock, boost::unique_lock, and
boost::condition_variable. It also removes usage of boost::shared_ptr
and boost::weak_ptr outside of block definitions (which must continue to
use Boost until GNU Radio 3.9).

Piotr Krysik 8cf6840da1 cmake: Go back CMake min ver. 3.8 by removing need for CMP0079 
CMake 3.13 is not present in older (~2 years old)
Linux distributions and GNU Radio requires min CMake
version 3.8.

All that is needed in order to avoid bumping CMake version
is to not use 'target_link_libraries' in subdirectories.
Here this is done by creating a list of needed
libraries and adding them for linking at the end (like
it was done in gr-osmosdr before porting to GNU Radio 3.8).

One thing that is lost here is 'PRIVATE' statement in case
of FCD libraries linking.

Krzysztof Halasa 33a8d1c2ae RTL-SDR: convert _lut to float[] to reduce size by a factor of 256 
The _lut is being indexed by I + Q (16 bits = 65536 entries), however
both samples can be processed independently, resulting in 8-bit LUT.
Saves a bit of RAM and CPU cache.

Jiří Pinkava 225faa2e6a rtl: fix large output buffers handling 
When size of output buffer was larger than size of input buffer,
uderflow occured because no check on number of avalilable data was done.

This also improves buffer filling for large output buffers, fill output
until anny input is available.

Dimitri Stolnikov eb76e35689 osmosdr/rtl/miri/hackrf: use 15 buffers by default 
folowing rtl-sdr commit 89f73b183f2dac9c0dd75beca4cf2f77f20c4a36

So far we had 32 * 256KB which was a bit overkill, 15 are more than
enough.

15 was chosen instead of 16 because at least on Linux there seems to be
a system-wide limit of 63 transfers (when they are 256KB large), so 4
dongles can be used on a single machine without lowering the default
transfer number.

Dimitri Stolnikov 0edfcfcba0 rtl: remove residue DC component introduced by RTL chip 
received from Juha Vierinen:

A student here noticed that there is dc bias even with the rafael tuner.
We looked into this issue and found that using 127.4f instead of 127.5f
removes this bias. I assume this is associated with a bug in the digital
downconversion of the RTL chip. This change fixes the problem.
