cli: search: Move more variables into search_context_t

In order to share some command line options between search and address
subcommands we need to add corresponding variables to the context
structure. While we are at it, we also add notmuch_database_t to unify
parameters of all do_search_* functions and to simplify subsequent
commits.

Otherwise, there are no functional changes.
