[PATCH v4 5/6] tag: use pgp_verify_function in tag -v call

From: Santiago Torres <redacted>

Instead of running the verify-tag plumbing command, we use the
pgp_verify_tag(). This avoids the usage of an extra fork call. To do
this, we extend the number of parameters that tag.c takes, and
verify-tag passes. Redundant calls done in the pgp_verify_tag function
are removed.

	Note: This follows Peff's suggestion to use an adapter, instead of 
changing the the fn* pointer structure to match gpg_verify_tag.
