* Bump to Xcode 9 beta 2
* [CoreImage] Stub out new CIImage filters in Xcode 9 beta 2.
* [monotouch-test] Update tests according to Xcode 9 beta 2.
* [xharness] Ask watch simulator tests to write output directly to a file.
It seems the watch simulator in Xcode 9 beta 2 has completely lost network
access (everything times out), so instead ask the tests to store results
directly in the resulting file.
This works for now since the watch simulator does not enforce the sandbox.
* [xharness] Rewrite the logic to write unit output to a file so that it works with Jenkins.
For Jenkins we ask the unit tests to produce XML, and this needs some special
treatment.
* [xharness] Protect against exceptions in the listener thread, so that it doesn't take xharness down.
* [xharness] Protect against a potential NullReferenceException, and fix one case where it would occur.
* [xharness] A few logging fixes.
* [Intents] Fix API & tests according to beta 2 changes.
Don't create multiple writer streams for the same underlying file, instead
store the writer stream on the log instance, and return it whenever needed.
This fixes an issue where there would be multiple writer streams, which could
cause exceptions when creating more writer streams (access defined errors
because the file is already open).
Fixes this warning:
SimpleHttpListener.cs(12,8): warning CS0108: `xharness.SimpleHttpListener.connected' hides inherited member `xharness.SimpleListener.connected'. Use the new keyword if hiding was intended
Make sure as much as possible is written to the logs, and not stdout.
Also copy an extra 1024 bytes when fetching the system log (and continue
capturing a while after stopped, since there may be unflushed system log
data in memory).
