(#3229) - Fix global access for node-webkit
(#136) - Fix "Changes since and limit new style" against CouchDB 2.0

Similar to previous commits, do not assume incremental sequence numbers.
(#136) - Fix "Changes limit old style" against CouchDB 2.0

Do not assume incremental sequence numbers in the test.
(#1738) - single batch() for leveldb bulkDocs()

This modifies leveldb's `bulkDocs()` so that it does
everything in a single batch. Note the addition
of the LevelTransaction to make it easier to
accomplish this.

`leveldb.js` is also refactored to use utils.processDocs,
just the same as idb and websql, cutting down on
code duplication.
(#136) - Ignore "changes last seq" against CouchDB 2.0

In clusterd CouchDB, the sequence number returned to the client is an
encoded representation of the various shard states. Whilst the last
"seq" value in _changes.results and the "last_seq" field should evaluate
to the same thing on the server, their encoded representation may differ.
Therefore, the assertions in this test don't hold for clustered CouchDB.
(#136) - Ignore tests for #3136 against CouchDB 2.0

These appear to be testing the internal PouchDB implementation of _changes.
Many of the assumptions don't hold against clustered CouchDB so skipping
them for now.
(#136) - Fix "changes limit and view instead of filter" against CouchDB 2.0

Do not assume incremental sequence numbers in the test.
This commit also adds a helper function to dig out specific items from
_changes (seems the simplest possible solution rather than importing
lodash or similar).
Merge pull request #3249 from willholley/136-changes-limit-and-view-instead-of-filter

(#136) - Fix "changes limit and view instead of filter" against CouchDB 2.0
(#136) - Fix "#3136 style=all_docs" against CouchDB 2.0

The _changes feed does not guarantee order so remove this assertion.
(#136) - Skip large doc_ids tests against CouchDB 2.0

CouchDB 2.0 does not (yet) support POST requests to _changes.
Re-enable when https://issues.apache.org/jira/browse/COUCHDB-2530 is fixed.
(#3251) - add read queue to avoid leveldb corruption
(#136) - Fix "#3136 style=all_docs & include_docs" against CouchDB 2.0

_changes feed does not guarantee order so remove this assertion.
(#3278) - Add hasOwnProperty check for IE11
(#3281) - refactor websql

Also moved http.js to http/http.js for consistency.

Also finally got rid of the need to manually add ok=true
for `bulkDocs`'s _local responses; `utils.processDocs` now
handles that.
(#3286) - test in Chrome 36

Chrome 36 had no blob support, 37 was when they added broken
support, and 38 was when it was finally fixed.

I would like to test in all three. Chrome is the most popular
desktop browser on the planet, and it's also very close
to what mobile Android users experience. Let's play it safe
and test all three versions.
(#3287) - explicitly set fs to false in browser env
(#136) - Fix "changes to same doc are grouped" against CouchDB 2.0

Do not assume ordering of _changes and remove the sequence number
assertion. Sequence numbers in clustered CouchDB cannot be tested for equality
without decoding them into the Erlang representation.
(#136) - Fix "Changes with conflicts are handled correctly" against CouchDB 2.0

Do not assume ordering of _changes in the test. CouchDB 2.0 does not
currently handle ?conflicts=true when fetching _changes (COUCHDB-2518)
so skip these assertions for now when testing against CouchDB master.
(#3262) - Minor style fixes

Inlined some unnecessary function calls, extraced some re-used logic,
indented a few things.
