pure: provide more correct implementation of posixfile for Windows

requires ctypes

Why is posixfile a class?

Because the implementation needs to use the Python library call os.fdopen [1],
which sets the 'name' attribute on the Python file object it creates to the
mostly meaningless string '<fdopen>', since file descriptors don't have a name.

But users of posixfile depend on the name attribute [2] being set to a proper
value, like Python's built-in 'open' function sets it on file objects.

Python file's name attribute is read-only, so we can't just assign to it after
the file object has alrady been created.

To solve this problem, we save the name of the file on a wrapper object,
and delegate the file function calls to the wrapped (private) file object
using __getattr__.

Test 'file:' uri handling:

  $ hg pull -q file://../test-doesnt-exist
  abort: file:// URLs can only refer to localhost
  [255]

  $ hg pull -q file://../test
  abort: file:// URLs can only refer to localhost
  [255]

  $ hg pull -q file:../test

It's tricky to make file:// URLs working on every platform with
regular shell commands.

  $ URL=`python -c "import os; print 'file://foobar' + ('/' + os.getcwd().replace(os.sep, '/')).replace('//', '/') + '/../test'"`
  $ hg pull -q "$URL"
  abort: file:// URLs can only refer to localhost
  [255]

  $ URL=`python -c "import os; print 'file://localhost' + ('/' + os.getcwd().replace(os.sep, '/')).replace('//', '/') + '/../test'"`
  $ hg pull -q "$URL"
