Projections used within an aggregation pipeline can result in empty documents emitted by the driver. We now guarded those cases and skip those documents within a Flux or simply return an empty Mono depending on the methods signature.

AsyncInputStreamAdapter now properly splits and buffers incoming DataBuffers according the read requests of AsyncInputStream.read(…) calls.
Previously, the adapter used the input buffer size to be used as the output buffer size. A larger DataBuffer than the transfer buffer handed in through read(…) caused a BufferOverflow.

We now rely on an outer drain-loop when GridFS reads complete on the same thread instead of using recursive subscriptions to avoid StackOverflow. Previously, we recursively invoked subscriptions that lead to an increased stack size.

maxTimeMs defines the time limit for the aggregation operations. If not specified or set to zero, operations will not time out.

Execution time and test order changed by using JUnit5. This commit fixes some of the issues related to index creation where actually not needed.

This commit switches from simple collection.count(), operating on potentially false collection statistic, to countDocuments() using an aggregation for accurate results.
The transition required query modifications at some points because $match does not support $near and $nearSphere but require $geoWithin along with $center or $centerSphere which does not support $minDistance (see https://jira.mongodb.org/browse/SERVER-37043).
$geoWithin further more does not sort results by distance, but this fact can be ignored when just counting matches.
Examples:
{ location : { $near : [-73.99171, 40.738868], $maxDistance : 1.1 } }
{ location : { $geoWithin : { $center: [ [-73.99171, 40.738868], 1.1] } } }
{ location : { $near : [-73.99171, 40.738868], $minDistance : 0.1, $maxDistance : 1.1 } }
{$and :[ { $nor :[ { location :{ $geoWithin :{ $center :[ [-73.99171, 40.738868 ], 0.01] } } } ]}, { location :{ $geoWithin :{ $center :[ [-73.99171, 40.738868 ], 1.1] } } } ] }

Add author tags. Move integration tests to existing test class.
Apply more appropriate in existing tests assertions. Use diamond syntax.

We now consistently use GridFSFile.getId() to allow custom Id usage instead of enforcing the Id to be an ObjectId. Using the native Id allows interaction with files that use a custom Id type.

Internal field references to $$this and $$value are now no longer mapped against exposed fields which had caused errors before.
Original pull request: #792.
Exceptions during CursorReadingTask startup and during polling are handled now by the same exception handling to handle Exceptions only once and notify ErrorHandler exactly once per exception.
Previously, startup exceptions relied on exception handling in the execute closure and notified ErrorHandler potentially multiple times.
