Split ameth arrays into individual methods

For some reason DSA, GOST, and RSA had their ASN.1 methods stored in
an array. This is clumsy and the only benefit is that one saves a few
externs in p_lib.c. They were also arranged by ascending NID because
of bsearch() madness.

Split them up and arrange the methods by name, which is much saner
and simpler.
