repro patch set to mono tree (with external/rx)

This is (sorry to say again) non-unit test case that was found during import of into mono.

It seems that mcs fails to resolve method invocations to the _private_ one
(which is wrong) in the nearest ancestor, instead of the expected _internal_
further ancestors.


Almost the same as bug #8320, but with the updated patch attached here this
time. You could remove mcs/class/*Reactive* and [checkout mcs/class/Makefile
and re-apply add-rx-libs.patch] or [edit mcs/class/Makefile and add
System.Reactive.Debugger]. This patch updates involves some Makefile changes,
additional sources and additional build args, so you most likely want to remove
old directories.

Then run "make run-test"

(Actually I tried to create simpler repro but I couldn't.)

Actual Results:

Failures like this:

67) ReactiveTests.Tests.RegressionTest.Bug_1297_Catch_Single :
System.MethodAccessException : Method
`System.Reactive.TailRecursiveSink`1<int>:Dispose ()' is inaccessible from
method `System.Reactive.Linq.ObservĪ±ble.Catch`1/_<int>:Done ()'

at System.Reactive.TailRecursiveSink`1[System.Int32].MoveNext () [0x0019c] in
at System.Reactive.Concurrency.AsyncLock.Wait (System.Action action) [0x000b6]

Expected Results:

none of the errors above.

Additional Notes:

The updated patch set contains an additional patch to "System.Reactive.Linq" in
rx tree. In the updated patch archive, there is
"internals-visibleto-workaround.patch". It actually describes the bug. With
this patch, those problematic NUnit failures are gone. The patch changes the
call target to the appropriate base class that contains the exact target
internal method to resolve.

I set up shrunk source tree of MS rx at

If you checkout "rx-oss-v1.0" branch, it is already applied the patches inside
Rx.NET tree.

I forgot to attach a public key for rx assemblies that is now referenced by
each "MonoAssemblyInfo.cs" file.
