438ba45c16 Fix acquisition with rata rates higher than 16 Msps in 4ms code periods

8d8249247f Alternative fix for issue #31
Rather than changing the index type to uint16_t, I think it would be
better to use the volk_32f_index_max32* functions instead of the 16 bit
counterparts. This ensures backwards compatibility (the index was
previously 32 bit, even if the function name indicated that it was 16
bit) and also, for FFT acquisition we may encounter large FFTs with more
than 65 535 points

24e62c4e4e Make use of volk_gnsssdr_malloc, volk_gnsssdr_free
instead of volk_malloc, volk_free (which are missing from the volk
version distributed by ubuntu 14.04). Fix the include guard in
volk_gnsssdr_malloc.h 
Thanks to @hoernchen

5a73b4e047 Improve package reproducibility
Packages using CMake often use file(GLOB ...) to retrieve a list of
source files. As this is based on readdir(), the resulting file list
is unsorted. A common use case is to pass this list directly to
add_executable or add_library. But as the order is unpredictable, the
binaries are not reproducible (because the order in which the objects
are linked will vary).

5b9683baad Multiple changes pcps acquisition: including linear corr.
Reduced zero_padding_factor in pcps acquisition

This was 16, I'm processing data at about 16MHz, this oversampling
factor caused memory allocation issues

Previously dump file name was not being read from the configuration

Added fix for non-zero IF in pcps_acquisition_cc

Added linear correlation to pcps acquisition.
