It closes more than before.

Add unload_extensions() method to unload all extensions; called from
_close().  It calls an extension's close() method if it has one.

Unregister everything at closing.
Don't call close() in __del__, rely on explicit call to close().

Make argument names equal to what is used in the documentation of the
file object, since chunks are supposedly file-like.

I just noticed that the changes below also apply to cmpcache.py, which
is virtually identical to cmp.py.

1. Fix incorrect file open mode on Win32 platforms (use "rb" instead
of "r").

2. Add shallow parameter to cmp.cmp().  If false, deep file
comparisons are made.

The module should be 100 percent backwards compatible.

avoid being fooled into thinking that fcntl and FCNTL are the same
thing -- they aren't!  (fcntl is the extension, FCNTL.py is h2py
output that defines all the constants).

(XXX The example is still weird -- I think there's a more portable way
to do locking now.  That's for someone else to fix...)

Urllib makes the URL of the opened file available through the geturl
method of the returned object.  For local files, this consists of
file: plus the name of the file.  This results in an invalid URL if
the file name was relative.  This patch fixes this so that the
returned URL is just a relative URL in that case.  When the file name
is absolute, the URL returned is of the form file:///absolute/path.

[I guess that a URL of the form "file:foo.html" is illegal...  GvR]

"""
When there are additional Setup files, specified by -e option of freeze,
checkextenstions.py assumes that *.o, *.a, -Lpath, and -Rpath are all
relative to where the Setup file is. select() inserts the path to the
Setup file to make them absolute. However, the assumption is not true.
There are cases that absolute paths are specified for them. The inserted
prefix, by select(), results in error.

The following fix check for absolute paths. The assumption is: an
absolute path begins with either '/' or '$'. In the latter case, it is
from the environmental variable. (Variables defined locally in the Setup
file have already been handled by expandvars())
