patchbomb: display terse series summary and ask for confirmation

The prompt can be avoided with -y/--noninteractive.

Confirmation check summary:

Subject: subject, including flags, of first message in series
From: sender
To: recipient(s) or prompt for To
Cc: carbon copy recipients
Bcc: blind carbon copy recipients

test-patchbomb does not change as it runs in noninteractive mode.
