Heikki Linnakangas 32984d8fc3 Add functions for dealing with PGP armor header lines to pgcrypto.
This add a new pgp_armor_headers function to extract armor headers from an
ASCII-armored blob, and a new overloaded variant of the armor function, for
constructing an ASCII-armor with extra headers.

Marko Tiikkaja and me.
