[PATCH v4 0/7] cli: improved crypto internals

[Jameson Graef Rollins]

Ok, hopefully last version.  This addresses Jani's latest comments.

The first patch uses a typedef to handle the incompatibility between
the crypto context between GMIME 2.4 and 2.6.  We probably should have
done this originally, as it gets rid of a bunch of #ifdefs, and should
help reduce confusion.

I also move to use strcasecmp for the crypto protocol, with a comment
that points to the relevant RFCs for justification.

jamie.
