SmtpClient: fix Timeout for low values (dotnet/corefx#37462)

* SmtpClient: fix Timeout for low values

The timeout is triggered from a Timer.
There were two race conditions:
- The timer event could occur before there was a connection to abort.
- The connection abort performs a TcpClient.Dispose, which may not
work when there is a TcpClient.Connect occurring simultaneously.

Fix PLINQ outerloop tests (dotnet/corefx#40589)

* Revert dotnet/corefx#40415's changes to PLINQ tests

They broke outerloop significantly.

* Fix MemberData(BinaryOperations) usage in PLINQ

Lots of outerloop tests are failing because xunit is preferring the wrong overload of the BinaryOperations method via reflection.  This just renames some of the methods to avoid the overloads.

Clean up JsonElementWriteTests (dotnet/corefx#40468)

* Make JsonElementWriteTests and JsonDocumentWriteTests share drivers
* Fix the casing of all escaped values in these tests (reducing the need for normalization)

Contribute to StyleCop SA1002 (semicolon spacing)

However, I'm not enabling the rule permanently, as it disagrees with VS IDE0055 about the spacing around semicolons at the end of empty while and for loops.

Because this also impacts `for (;;)` loops, I also searched and replaced those with `while (true)`, to standardize on that across the codebase.
