-----------------
This "description" (if one chooses to call it that) needed some major updating
so here goes. This update addresses a change being made at the same time to
OpenSSL, and it pretty much completely restructures the underlying mechanics of
the "ENGINE" code. So it serves a double purpose of being a "ENGINE internals
for masochists" document *and* a rather extensive commit log message. (I'd get
lynched for sticking all this in CHANGES or the commit mails :-).
ENGINE_TABLE underlies this restructuring, as described in the internal header
"eng_int.h", implemented in eng_table.c, and used in each of the "class" files;
tb_rsa.c, tb_dsa.c, etc.
However, "EVP_CIPHER" underlies the motivation and design of ENGINE_TABLE so
I'll mention a bit about that first. EVP_CIPHER (and most of this applies
equally to EVP_MD for digests) is both a "method" and a algorithm/mode
identifier that, in the current API, "lingers". These cipher description +
implementation structures can be defined or ob
