Carles Fernandez bd6c028ec4 bug fix 
writing to the input pointer was having bad consequences (random fails
in other kernels)

Carles Fernandez 485a405bab Adding new neon kernel and solving x86 issues 
Managing memory with volk_gnsssdr instead of malloc and free. This seems
to solve runtime problems (segmentation faults) in i386 (32 bit)
architectures.

Carles Fernandez 883cf629d1 Adding new NEON protokernel 
Try another strategy based on multiply-and-accumulate for the dot
product. In all SIMD protokernels, managing memory with
volk_gnsssdr_malloc and volk_gnsssdr_free instead of calloc and free

Carles Fernandez a3d7683c85 Fix segmentation fault of volk_gnsssdr_profile in 32-bit architectures 
Temporal deactivation of the unaligned protokernel of the multiple
correlator. It does not affect receiver's performance. The commit
includes other minor fixes.

Carles Fernandez 26ff3dbe1c main returns 0 upon normal ternimation 
The return value for main should indicate how the program exited. Normal
exit is generally represented by a 0 return value from main. Abnormal
termination is usually signalled by a non-zero return but there is no
standard for how non-zero codes are interpreted

Javier Arribas 4480c12d94 Added a non CFAR PCPS acquisition algorithm based on the estimation of 
the post correlation noise floor. If enabled

behavior of front-ends....)
