2b46c79ba7 optimized the process of computing and writing the fft of the local code to the acquisition HW accelerator. 
The writing of the local code is still performed by processor instructions in a loop.
THe FPGA L2 classes were updated accordingly.

2bae20d2fd Merge branch 'next' of https://github.com/gnss-sdr/gnss-sdr into fpga 
added second acquisition to reduce the time between acquisition and tracking when using the FPGA
moved the process of writing of the tracking local code to the HW accelerator from the start_tracking() function to the set_gnss_synchro() function (this is only applicable for the FPGA case)
there was a bug in the computation of the tracking starting position for the L1/E1 band when using the FPGA, only high sample counter values (>31 bits) were affected, due to a uint64_t*float mult.

cb59c1cc83 Fix bug in MacOS when BeiDou was enabled in rtklib.h 
The BLAS and LAPACK implementations that come with the Accelerate Framework (soft-linked in /usr/bin) caused a random crash when exiting the program, only if the variable ENABDS was set. This bug disappears when linking to the libraries that Homebrew or Macports install, or when manually downloaded, built and installed by the user
