We had been implicitly assuming that clients send us sorted groups, but
unsurprisingly that's not always the case. The additional sorting here
should be redundant, but the consequences of merging unsorted groups are
severe -- we can end up with uniqueness violations on the primary key in
the database -- and so we add an additional sort here.

COUCHDB-2735

Document buckets are sorted by docid, but the validation code was
reversing the buckets. If multiple clients send concurrent updates for
the same document the broken sorting can result in duplicate documents.

The particular structure of the patch here is chosen to match the 2.x
codebase.

COUCHDB-2735

Admin users are stored in .ini files and are not full-fledged user
documents. Internally, a fake document is made to allow insertion into
the auth cache. CouchDB 1.6 introduced a feature to upgrade password
hashes from the legacy simple hash scheme to the stronger PBKDF2
scheme. It inappropriately attempted to do this to the fake admin
docs, which do not pass the _design/_auth validation checks. This is
fortunate, however, as CouchDB would then have written the admin users
into the users database causing widespread confusion and fear.

Further updating instances of <%= and to <%- within documents to correctly handle HTML interpolation.

Tested for regression in
- 34.0.1847.131
- Safari 7.0.2

R14B01 and R14B02 both are affected to OTP-9167 Erlang issue which
causes 4 tests failure because supervisor restarts worker with old
ChildSpec ignoring changes in use_checkpoint options.

This fix makes all tests passed, but leaves a notice in verbose mode
that there is a problem and how it could be resolved.

Another possible solution is to isolate test_use_checkpoints calls, but
this will be only hide the issue while it still may happened in prod.

  - I tried to not be super heavy handed, only using <%- for values that
    could be set with XSS payloads or otherwise come from a user/data.
