Docs: add synopsis, deprecated and noindex options to HTTP endpoints

Synopsis is the short description of the HTTP endpoint that used in
the generated API reference.

Deprecated option, if specified, adds special remark to the endpoint
description in the same reference.

Noindex excludes endpoint from the reference.

The old source of synopsises is removed.
Docs: fix CouchDB.info file generation

It was broken due to long lines with { } chars in HTTP API index
which was wrapped to fit 80 chars per line limit. Since { } chars
have some special meaning for texinfo, they should be escaped with
@ char, but due to wrapping this escaping becomes broken which leads to
to syntax error.
Update Sequence had the wrong label.  Missing closing tag for wrapper.

Extend support for attachment-related query params

Until now, the boolean query parameters `attachments` and
`att_encoding_info` have only been supported for the document API
endpoint (`/{db}/{docid}`).

This extends support for queries to the changes (`/{db}/_changes`) and
view (`/{db}/_design/{ddoc}/_view/{view}`) API endpoints:

* If `include_docs` and `attachments` equal `true`, the Base64-encoded
  contents of attachments are included with the documents in changes or
  view query results, respectively.

* If `include_docs` and `att_encoding_info` equal `true`, encoding
  information is included in attachment stubs if the particular
  attachment is compressed.

Closes COUCHDB-1923.
