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.

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

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.

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
