Test WebClient asynchronous uploads cancellation.
Tests that UploadStringAsync triggers UploadStringCompleted with Cancelled == true.
Tests that UploadDataAsync triggers UploadDataCompleted with Cancelled == true.
Tests that UploadValuesAsync triggers UploadValuesCompleted with Cancelled == true.
Tests that UploadFileAsync triggers UploadFileCompleted with Cancelled == true.
[runtime] Applied patch from Kyle Edwards <kyleedwardsny@gmail.com>. Fix isinf () check with clang. Fixes #20244.
[mcs] Update new error codes
Changed UploadStringAsync to handle UploadString encapsulated exceptions.
UploadString call UploadData that encapsulates all exceptions in a WebException. ThreadInterruptedException were encapsulated into a WebException, so UploadStringAsync now uses e.InnerException is ThreadInterruptedException instead of trying to catch it.
[bcl] Disable a test added by 3cf55e6016811ce115ef47fbb9636f10d4b62789, it depends on precise gc behaviour.
[runtime] Add an EXTRA_DISABLED_TESTS make variable to disable tests on the command line.

Test JavaScriptSerializer.Deserialize with nullable enums. Covers #19287.
Improved JavaScriptSerializer.ConvertToType Nullable handling. Fixes #19287. ConvertToType was returning null even when the object was not a string. When the target type is Nullable, ConvertToType returns null if the object is an empty string, if the object is not a string and the target type is obtainable from a string then the object is converted to a string and the string to the target type.
