Basic changes:
* Change `catch` function to propagate exceptions using the
WhileHandling mechanism.
* Introduce `catchNoPropagate`, which does the same as before, but
passes an exception which can be rethrown.
* Introduce `rethrowIO` combinator, which rethrows an exception with a
context and doesn't add a new backtrace.
* Introduce `tryWithContext` for a variant of `try` which can rethrow
the exception with it's original context.
* onException is modified to rethrow the original error rather than
creating a new callstack.
* Functions which rethrow in GHC.Internal.IO.Handle.FD,
GHC.Internal.IO.Handle.Internals, GHC.Internal.IO.Handle.Text, and
GHC.Internal.System.IO.Error are modified to not add a new callstack.
Implements CLC proposal#202 <https://github.com/haskell/core-libraries-committee/issues/202>
