ISA-L Cauchy support
This is for supporting ISA-L cauchy based matrix. The difference
from isa_l_rs_vand is only the matrix to use the encode/decode calculation.
As a known issue, isa_l_rs_vand backend has constraint for the
combinations of the available fragment to be able to decode/reconstuct.
(See related change in detail)
To avoid the constraint, this patch adds another isa-l backend to use
cauchy matrix and keep the backward compatibility, this is in
another isa_l_rs_cauchy namespace.
For implementation consieration, the code is almost same except the matrix
generation fucntion so that this patch makes isa_l_common.c file for
gathering common fucntions like init/encode/decode/reconstruct. And then the
common init funciton takes an extra args "gen_matrix_func_name" for entry
point to load the fucntion by dlsym from isa-l .so file.
