MB-8877 Fix builtin reduces for subset development views

The regression was introduced in the commit
912b8667560a275a652a2ff0d9d9264ed38e9328:

"MB-7978 Fixes to view tree with multiple reducers"

It only affects 2.1.0, 2.1.1 and 2.2.0 releases. The 3.0 (master branch)
is unaffected, because the same view engine is used for both development
and production views, unlike previous releases.

MB-7978 Fixes to view tree with multiple reducers

A view tree with multiple reducers where not all of them
are native (_count, _sum, _stats) or custom (JavaScript)
was not working anymore since the termless storage format,
and it became undetected for so long due to the fact that
old JavaScript testsuite (Futon) was removed (commit
304cbbd93400abfcb07ca70eecb4e1ccf3f3b485) and no equivalent
etap tests existed.

A view tree with multiple reducers only exists when 2 or
more views in the same design document have exactly the same
map function, on a byte by byte basis, and different reduce
functions (builtin or custom).

CBD-456 Separate document body and meta arguments to map function

Sends non-JSON values as byte arrays for the 'doc' argument.
Numbers and ascii text can be decoded trivially from this capability,
extending our support for legacy applications.

The document JSON format on the wire for bulk docs operations
now looks like this:

{
"json":{"user":"data","_anything":"goes"},
"meta":{"id":"mydocid"}
}

Or like this:

{
"base64":"bXliYXNlNjRiaW5hcnlkYXRh",
"meta":{"id":"mydocid"}
}

There can be additional data in the metadata object. Specification is on
the Jira ticket.

This change off support for _id lookups in include_docs queries, although
with server level include docs going away as well, this change should
be of little consequence. Include_docs is not removed as it is used
heavily by tests, in the future it will be renamed to x_include_docs
across both tests and query parser, in order to reflect the non-
supported nature.

Ticket with the specifications documentation:
http://www.couchbase.com/issues/browse/CBD-456

Admin UI and ns_server changes are in this change:
http://review.couchbase.org/#change,18028

Depends on this change in testrunner for view tests:
http://review.couchbase.org/#change,17768

Squashed in an old patch: http://review.couchbase.org/#change,18111

TODO: EP engine doesn't need to check for _fields when setting JSON
flag. This can be accomplished in a future patch.

Related issue (not addressed by this patch): views and _all_docs
output (as well as XDCR JSON format) needs to understand non-UTF8
