Patch adding debug feature printing the public key

When debugging and when performing forensic analysis it can be helpful to print out the full public key.

This patch provides that functionality when debug level set to 1 or more.

Same patch embodied in github pull request here:

base64 and log key blob early

I think doing it a little earlier would be useful as it would allow debugging of problems with the key itself. Since we already have the key blob, we can just base64 encode that.

BTW I think debug2() is a better log level for this
