Prevents ARM CPU's from reordering read/write
sequences such that writes to a guard variable
are reordered ahead of reads.

In this case, our task scheduler was periodically
allowing two concurrent tasks using shared
state, causing one to overwrite the other.

Fixes #272.
Bumped nuget package version.
While running unit tests, came across a case where "Cancel()" could be called after the object was disposed since the value was not null.
When syncing with CouchDB (in the iOS 8 Simulator) the initial linq query would return 2 values.  The first value would be an actual header value, the second value would be null, thus causing an exception in String.Join.  Added the where clause to filter out any null values.
There seemed to be a missing AsyncTaskStarted call in the MaybeCreateRemoteDB() method.

The id's that Couchbase Lite generates and the id's that CouchDB return don't match case, to had to change from a "Contains" to case insensitive search.

Xamarin.Android has a bug in the network reachability

This works around that bug, which will soon be fixed,
by implementing platform-specific on Android.
