Also, update versions in README to 0.8.0

Used to link to the image, which wasn't super useful.

Previously BlockingProcessStreamReader has a terminate() method,
used to tell the Reader to stop reading from the emulator process.

This causes an inter-process race.
If the Reader stops before reading emulator's output,
the emulator process will hang as it tries to write to stdout/stderr
as there's no one to read from the other side of the pipe.

Since there is no way to safely stop the Reader,
this commit deletes the method and its associated test.

Additionally, the timeout for LocalSystemTest is increased to 3 minutes,
since the emulator, somehow, consistently takes just longer than a
minute to shut down.

fix more races in pubsub tests

* Converting Error Reporting and Monitoring to use resource name types
* Removing formatX/parseX methods from pubsub, converting usage of the
  same to resource name types
* New methods in Logging and PubSub

Original code snippet in _"Querying data"_ section: 

`..while (!queryResponse.jobComplete()) {..`

This results in a compile error: 

_"Cannot resolve method jobComplete()"_

The correct method is `jobCompleted()`

Fix code snippet (wrong method name) in README.md

* This makes it easier for users who start with a URI describing a full
path to get a FileSystem that can work with that path, since they no
longer have to needlessly remove the path from the URI.

Note that Oracle's description of newFileSystem [1] puts no restriction
on the passed URI.

* Preventing logging re-entrance at FINE level

Also:
* Reducing the scope of synchronized blocks
* Removing logger exclusions except for Http2FrameLogger

Add a test, as well.
We reuse the default PathMatcher since it does a fine job of globbing files.

#1441

Added new constant in FormatOptions, and a corresponding factory method. Updated test cases. Confirmed that AVRO does not require special treatment (like CSV does), so no additional changes are required.

BigQuery: Add support to FormatOptions for AVRO

* use RpcFuture and remove old BundlingSettings

Note: This version was accidentally released to Sonatype because of
experimenting with deployment commands, combined with the fact that
autoReleaseAfterClose is set to true. Since releases can't be taken
back, we might as well own up to the release and push the code
forward.
