Are the name fields in the ecc_curve structures used anywhere or
exposed to userspace?

It'd be nice if the strings for the nist_p192, nist_p256, and nist_p384 
structures and this new nist_p521 structure included "p" before
the number, better matching all the code and the NIST FIPS 186-4 names:
    .name = "nist_p192"
    .name = "nist_p256"
    .name = "nist_p384"
    .name = "nist_p521"
