Fix scrolling in SWF.ListView.EnsureVisible(int index)

This fixes https://bugzilla.xamarin.com/show_bug.cgi?id=22483
[mdoc] New make test for the --dropns functionality
[mdoc] New make test, reproduces issue with --dropns when run with a secondary assembly that doesn't drop the specified namespace
[mdoc] added -dropns-assemblies parameter.
Will now only replace the namespace when the type or member is in a listed assembly
[mdoc] Formatting feedback from pull #1273
[mdoc] consolidated dropns and dropns-assemblies into a single parameter.

Based on pull request feedback, this is a simpler usage, and meets our required use-case. A sample version of this parameter would be: `--dropns MyUnifiedAssembly=MyDroppedPrefix`
[System] Add performanceCounters element to System.Diagnostics app.config configuration section

See http://msdn.microsoft.com/en-us/library/ms229387(v=vs.110).aspx for details about the element.
The value that is set by the element isn't currently used in Mono, but applications using it in their app.config crash otherwise (e.g. http://stackoverflow.com/questions/25741651).

[mkbundle] Fix check for dos2unix

This fixes the command to check for dos2unix and makes mkbundle usable again with mingw.
We need first to redirect the standard input, otherwise the check always fails with an InvalidOperationException and set CreateNoWindow=false to avoid spawning a new window.
