New asynchronous exception control API (ghc parts)

As discussed on the libraries/haskell-cafe mailing lists
  http://www.haskell.org/pipermail/libraries/2010-April/013420.html

This is a replacement for block/unblock in the asychronous exceptions
API to fix a problem whereby a function could unblock asynchronous
exceptions even if called within a blocked context.

The new terminology is "mask" rather than "block" (to avoid confusion
due to overloaded meanings of the latter).

In GHC, we changed the names of some primops:

  blockAsyncExceptions#   -> maskAsyncExceptions#
  unblockAsyncExceptions# -> unmaskAsyncExceptions#
  asyncExceptionsBlocked# -> getMaskingState#

and added one new primop:

  maskUninterruptible#

See the accompanying patch to libraries/base for the API changes.
