    Rewrite case-mashing symlink generation.
    
    The previous version had several bugs. Firstly, it did the wrong thing
    with symlinks in subdirectories: if it saw '#include <Foo/Bar.h>' in a
    header, then it would write a symlink at Foo/Bar.h whose actual link
    text was "foo/bar.h", which doesn't work, because symlinks are
    relative to the link file itself, so just "bar.h" would have been
    appropriate.
    
    Secondly, it could only cope with one layer of subdirectories, because
    I looked for a '/' in the pathname using strcspn and then trimmed
    everything _after_ it. If you're doing it that way round, you need to
    use strrchr.
    
    And thirdly, it couldn't cope with input paths containing backslashes,
    and would simply complain on standard error if it saw one.
    
    The rewrite solves all of these, I think. It now copes even if it sees
    a mixed-slash include such as '#include <Foo/Bar\Baz/Quux.h>', and
    will output links
    
       Foo -> foo
       foo/Bar\Baz -> bar/baz       (leaf name of link is all of 'Bar\Baz')
       foo/bar/baz/Quux.h -> quux.h
    
    so that the pathname as a whole should actually work if read by a Unix
    compiler.

    Rewrite setup script output.
    
    The new-look setup script is much more idiomatically Python 3 than the
    version I hastily converted in commit 84d90e5eb9. Also, alongside it,
    there's a new 'make-wrapper.py', which you can give the full pathname
    of some other binary (such as clang-cl or lld-link), and it will write
    out a wrapper shell script of the same name which sets up INCLUDE and
    LIB appropriately. My plan is to use that to arrange a method of
    building with this setup that doesn't require pre-set environment
    variables at build time: instead, you point your build script at these
    wrappers in place of the real binaries, and everything just works.
