Remove MAX_PATH restrictions from RTS, I/O manager and various utilities
Summary:
This shims out fopen and sopen so that they use modern APIs under the hood
along with namespaced paths.
This lifts the MAX_PATH restrictions from Haskell programs and makes the new
limit ~32k.
There are only some slight caveats that have been documented.
Some utilities have not been upgraded such as lndir, since all these things are
different cabal packages I have been forced to copy the source in different places
which is less than ideal. But it's the only way to keep sdist working.
