* keygen.c (gen_elg, gen_dsa, gen_rsa, do_create, do_generate_keypair,

generate_subkeypair): New is_subkey argument to set whether a generated
key is a subkey.  Do not overload the ret_sk.  This is some early cleanup
to do backsigs for signing subkeys.

* keygen.c (write_keybinding, do_generate_keypair, generate_subkeypair):
Keep track of the unprotected subkey secret key so we can make a backsig
with it.

* keygen.c (make_backsig): New function to add a backsig to a binding sig
of signing subkeys.  Currently disabled. (write_keybinding): Call it here,
for signing subkeys only.

* sign.c (make_keysig_packet): Allow generating 0x19 signatures (same as
0x18 or 0x28, but used for backsigs).

* packet.h, build-packet.c (build_sig_subpkt): Add new SIGSUBPKT_SIGNATURE
type for embedded signatures.

Simplify code and properly handle a partial match against an
option with an argument.
