System.Net 1.x undocumented APIs

[carlossanlop]

@dotnet/ncl

Here are the undocumented API from System.Net. Some of them were introduced in 1.x, but there's also some debt from the 2.x effort.
We are asking all area owners to report back their plan/commitment for their undocumented APIs in order to tackle 33% of the APIs in the next month. Can you please help us with that?

For more information on the plan, see: #3904

Total: 63.
Note: The table has 4 really long columns.
