Andre Puschmann 43a6cd50e5 rf_imp: fix stopping of AGC thread 
hard killing of AGC thread causes issue on some RF devices,
such as the N310. The thread still seemed to access the device while
the radio was already killed (or the streamer object deleted).

It's unclear why this isn't causing similar issues on B210 or X310,
at least not visible, but it is obviously not the correct way to stop a thread.

The patch now correctly sets the stop flag for the AGC thread, wakes it
it up and waits until it has terminated.

gracid f67a152a2a Remove unnecessary Lime calibration step from Soapy implementation 
When using srsLTE with Lime devices, calibration was performed before any configuration steps have happened, thus making calibration values invalid. Removing Lime specific calibration step from rf_soapy_imp makes so that devices will be automatically calibrated by SoapyLMS on rf_soapy_start_stream call.

Tested and working with srsENB using LimeSDR-USB v1.4 and LimeSDR-Mini v1.2 boards.

Andre Puschmann 5e7de0a95b cmake: install individual libraries (common, phy, etc) 
this seems to be important for package maintainers
or people who use srslte components in other projects
thar require to link against static libs

so besides installing headers, the apps and the RF lib, we also
install all individual libraries

this fixes https://github.com/srsLTE/srsLTE/issues/500#

Jan Remeš 8c7b7cc55a libsrslte_rf: add library version 
This patch adds version string to the 'libsrslte_rf' library.
This results in the library being built as
    libsrslte_rf.so.20.04.2
with the following symbolic links
    libsrslte_rf.so.0 -> libsrslte_rf.so.20.04.2
    libsrslte_rf.so -> libsrslte_rf.so.0

The SRSLTE_SOVERSION variable should be increased with each backwards
incompatible change of the library.
