Thanks Daniele. Once Jenkins is done I'd like to have Todd final review it.

The lowest level of ECC signature verification does not require ASN. This patch allows to compile ECC with WOLFSSL_SP_MATH, removing the dependency on ASN module.
This is particularly useful in those embedded context where ECC signature verification is a requirement, but ASN is not an option due to resource restrictions (flash size).
Applications can now use
wc_ecc_import_unsignedto import a public key andwc_ecc_verify_hash_exto verify a signature, with no asn.c module compiled in.Tested with wolfBoot ECDSA branch.
Originally based on the sp_cortexm branch (see dgarske#3 for previous related discussion)
