[PATCH 0/6] cli: improve handling of crypto parameters contexts

[Jameson Graef Rollins]

I wanted to see if I could hack in S/MIME support, but ultimately
failed (the interface is too stupid for me to deal with at the
moment).  However, on the way there I did manage to make some tangible
improvements to how crypto is handled in show and reply.

Most importantly I've moved the initialization of the gpg context to
mime_node.c where it is created lazily, only when needed.  This should
provide some speed up in notmuch show and reply when crypto flags are
provided but the messages have no crypto parts.

I was also able to get rid of a bunch of those pesky
"#ifdef GMIME_ATLEAST_26" conditionals.

This should provide a better framework for someone to try to hack in
S/MIME support at a later date if they're so inclined.

jamie.
