Resolved issue #1033 (iostreams)

restrict.hpp:

• added static asserts to prevent using restrict with bidirectional filters and devices (since it would not be clear which of the two sequences is to be restricted). To restrict a bidirectional component, combine the restrictions of a read-only and a write-only view of the component, using combine() and detail::mode_adapter (which should probably be made public)
• added special treatment for dual_use filters, to make sure the "which" argument to seek is set correctly (although I don't know of any examples of seekable dual use filters)

skip.hpp:

• added a "which" parameter to skip() for filters
• added more fine-grained analysis of modes to determine whether to call the optimized version of detail::skip()
• added static asserts to rule out the case where skip is called with a non-seekable output-only device

test/close_test.cpp

• removed uses of restrict with bidirectional devices, since this doesn't make sense and is now officially prohibited
