[PATCH] doc: field processor support now always included, adjust manual pages

[Tomi Ollila <tomi.ollila@iki.fi>]

The features that require field processor support, are now just
documented w/o mentioning **Xapian Field Processors**' is needed
for those.

Replaced "compact" and "field_processor" with "retry_lock" in
build_with config option, as it is currently the only one that
is optionally excluded. The former 2 are now documented as
features always included.

Dropped one 'we' "passive" in notmuch-search-terms.rst. It was the
only one, and inconsistent with rest of the documentation in that
file.

Dropped message about conditional open-ended ranges support, as
those are now always supported.

-XAPIAN FIELD PROCESSORS
-=======================
-
-Certain optional features of the notmuch query processor rely on the
-presence of the Xapian field processor API. You can determine if your
-notmuch was built against a sufficiently recent version of Xapian by running
-
-::
-
-  % notmuch config get built_with.field_processor
-
-Currently the following features require field processor support:
-
-- non-range date queries, e.g. "date:today"
-- named queries e.g. "query:my_special_query"
-- regular expression searches, e.g. "subject:/^\\[SPAM\\]/"
-- thread subqueries, e.g. "thread:{from:bob}"
