M rpc.py
1. Additional debug messages in rpc.py

Allow arbitrary sequences on the RHS of extended slices.

This patch enables the bz2 module to build cleanly under Cygwin.

Although motived by Cygwin, this patch will prevent
test_commands from failing on Unixes that support
ACLs. For example, the following is an excerpt from
the Solaris ls manpage:

	...
	-rwxrwxrwx+ 1 smith dev 10876 May 16 9:42 part2

	The plus sign indicates that there is an ACL associated
	with the file.
	...

This patch updates regrtest.py to understand which
tests are normally skipped under Cygwin. The list of
tests was verified with the Cygwin Python maintainer.

Just van Rossum showed a weird, but clever way for pure python code to
trigger the BadInternalCall.  The C code had assumed that calling a class
constructor would return an instance of that class; however, classes that
abuse __new__ can invalidate that assumption.

resource isn't enabled or the socket module doesn't support ssl.

some of the more compilcated cases (CF, Res) haven't been done yet. Also,
various types should inherit from each other (anything with an as_Resource
method should be a Resource subtype, the CF types should become one family).

but can lead to mysterious problems in real applications.
