minor modifications to the Galileo E5a and GPS L5 acquisition adapters. Now the acquisition opens and closes the acquisition HW device every time an acquisition is done, to prevent the acquisition interrupt from interrupting all the acquisition processes at the same time.

Galileo E5a is now debugged and working. Acquisition is using interrupts again. Each acquisition process opens and closes the acquisition device when an acquisition is done instead of having the device opened all the time. In this way the acquisition interrupt should only be received by the process that is using the interrupt at that time.

updated the SW to run the new Acquisition HW accelerator, which compensates the scaling factors of the FFT and the IFFT, and computes the test statistics out of the peak value and the second peak value resulting from the correlation performed by the acquisition process. Updated the GPS L1 and Galileo E1 acquisition adapters.
