core: Add cert-notation support and extended-edit

* src/context.h (gpgme_context): Add new flag for extended-edit.
* src/engine-gpg.c (append_args_from_sig_notations): Add flags to
control the kind of notations.
(gpg_edit): Respect extended-edit and notations.
(gpg_encrypt_sign, gpg_sign): Update call to
append_args_from_sig_notations.
* src/gpgme.c (gpgme_set_ctx_flag, gpgme_get_ctx_flag): Support
extended-edit.
* NEWS, doc/gpgme.texi: Mention extended-edit.

This provides a way to get the extended key-edit interface without
breaking bad state machines that rely on the current command flow.

A use case for this is to enable multiple local signatures, which
can be used together with annotations for:

@item "extended-edit"
This flag passes the option @option{--expert} to gpg key edit. This
can be used to get additional callbacks in @code{gpgme_op_edit}.
@end table
This function returns @code{0} on success.
