adding initial support for ECDSA (19) to netpgp. tested using p256/sha256, p384/sha384, and p521/sha512

allow netpgp to absorb gpg2 subpkt 33 for list/enc/decrypt rsa keys

Fix some error handling, json support, keyring handling.

Fix compilation:
kill PGP_ERROR() and make everything use a format.
XXX: Fixme to use __VA_ARGS__ instead of the silly PGP_ERROR_N() macros.

There were still some throwbacks with the prefix '_ops' - rectify that to
be the standard "pgp_" - no functional change.

Don't prefix function names with "pgp_" if the functions are static.

Changes to help with netpgp key generation and interoperability:

+ use plain SHA1 for session key s2k negotiation
+ don't warn on some conditions when inflating (reading a compressed file)
since the conditions don't hold for partial block lengths
+ prompt for a passphrase when generating a new key - used in the upcoming
secret-sharing functionality for netpgp

This makes DSA keys into first class citizens, since encryption and
decryption using DSA/Elgamal is now supported.

+ add a pretty print function mj_pretty(3) to libmj
+ added netpgp_write_sshkey(3) to libnetpgp
+ added pgp2ssh(1)
+ added preliminary support for ElGamal decryption, needed for DSA keys
as yet untested, unworking, and a WIP
+ add support for using all ssh keys, even those protected by a passphrase,
for decryption and signing. This rounds off ssh key file support in netpgp.
+ add a single character alias [-S file] for [--sshkeyfile file] to
netpgpkeys(1) and netpgp(1)

As far as ssh key file support goes, see the following example:

% cp configure a
% netpgp -S ~/.ssh/id_rsa.pub -e a
% netpgp -S ~/.ssh/id_rsa.pub -d a.gpg
Enter PEM pass phrase:
% ls -al a a.gpg

Changes to 3.99.5

+ make ssh fingerprints (md5) match netpgp listing
+ use the more functional hexdump function from ssh2pgp in place of the
older hexdump function from openpgpsdk
+ pass hash type down from command line where needed

With these changes, netpgp can be made to generate the same fingerprint as
openssh (by default, ssh-keygen(1) uses an md5 digest)

PR 42922 applies - need to define _XOPEN_SOURCE and _BSD_SOURCE for
newer linux platforms with glibc 2.10.1. solved a bit differently, by
implementing strdup(3) and strcasecmp(3) independently, and using regexps
to avoid calling strptime(3).
