inherit_slots():  tp_as_buffer was getting inherited as if it were a
method pointer, rather than a pointer to a vector of method pointers.  As
a result, inheriting from a type that implemented buffer methods was
ineffective, leaving all the tp_as_buffer slots NULL in the subclass.

corresponding to a dispatch slot (e.g. __getitem__ or __add__) is set,
calculate the proper dispatch slot and propagate the change to all
subclasses.  Because of multiple inheritance, there's no easy way to
avoid always recursing down the tree of subclasses.  Who cares?

(There's more to do, but this works.  There's also a test for this now.)

The platform requires 8-byte alignment for doubles, but the GC header
was 12 bytes and that threw off the natural alignment of the double
members of a subtype of complex.  The fix puts the GC header into a
union with a double as the other member, to force no-looser-than
double alignment of GC headers.  On boxes that require 8-byte alignment
for doubles, this may add pad bytes to the GC header accordingly; ditto
for platforms that *prefer* 8-byte alignment for doubles.  On platforms
that don't care, it shouldn't change the memory layout (because the
size of the old GC header is certainly greater than the size of a double
on all platforms, so unioning with a double shouldn't change size or
alignment on such boxes).

SyntaxError.  Fix it.

Try to be systematic about dealing with socket and ssl exceptions in
FakeSocket.makefile().  The previous version of the code caught all
ssl errors and treated them as EOF, even though most of the errors
don't mean EOF.

An SSL error can mean on of three things:

    1. The SSL/TLS connection was closed.
    2. The operation should be retried.
    3. An error occurred.

Also, if a socket error occurred and the error was EINTR, retry the
call.  Otherwise, it was a legitimate error and the caller should
receive the exception.

The former does the right thing on Windows, the latter does not.

Use #define X509_NAME_MAXLEN for server/issuer length on an SSL
object.

Update doc strings for socket.ssl() and ssl methods read() and
write().

PySSL_SSLwrite(): Check return value and raise exception on error.
Use int for len instead of size_t.  (All the function the size_t obj
was passed to our from expected an int!)

PySSL_SSLread(): Check return value of PyArg_ParseTuple()!  More
robust checks of return values from SSL_read().

XXX Forgot to mention this in the last socketmodule.c checkin.

headers.  It does not parse the body of the message, instead simply
assigning it as a string to the container's payload.  This can be much
faster when you're only interested in a message's header.

convertbuffer() uses the buffer interface's getreadbuffer(), but 't'
should use getcharbuffer().

Change all the local names that start with SSL to start with PySSL.
The OpenSSL library defines lots of calls that start with "SSL_".  The
calls for Python's SSL objects also started with "SSL_".  This choice
made it really confusing to figure out which calls were to the library
and which calls were local to the file.

Add PySSL_SetError() that sets an exception based on the information
from SSL_get_error().  This function will eventually replace all the
calls that set it with an error message that is based on the name of
the call that failed rather than the reason it failed.  (Example: If
SSL_connect() failed it used to report "SSL_connect error" now it will
offer a specific message about why SSL_connect failed.)

    XXX It might be helpful to augment the error message generated
    below with the name of the SSL function that generated the error.
    I expect it's obvious most of the time.

Remove several unnecessary INCREFs in the module's constructor call.
PyDict_SetItem() and friends do the INCREF for you.

value, so the programmer will have to catch OverflowError.  I'm not sure
what /F's perspective is on this.  Perhaps it should be caught and mapped to
an xmlrpclib-specific exception.  None of the other type-specific dump
methods seem to do any exception handling though.

We have 5 implementations of walk(), and 5 different docstrings.  Combined

In SSL_dealloc(), free/dealloc them only if they're non-NULL.

Fixes some obvious core dumps, but not sure yet if there are more
semantics to the SSL calls that would affect the dealloc.

XXX [1] These changes aren't tested very thoroughly, because regrtest
doesn't do any SSL tests.  I've done some trivial tests on my own, but
don't really know how to use the key and cert files.  In one case, an
SSL-level error causes Python to dump core.  I'll get the fixed in the
next round of changes.

XXX [2] The checkin removes the x_attr member of the SSLObject struct.
I'm not sure if this is kosher for backwards compatibility at the
binary level.  Perhaps its safer to keep the member but keep it
assigned to NULL.

And the leaks?

newSSLObject() called PyDict_New(), stored the result in x_attr
without checking it, and later stored NULL in x_attr without doing
anything to the dict.  So the dict always leaks.  There is no further
reference to x_attr, so I just removed it completely.

The error cases in newSSLObject() passed the return value of
PyString_FromString() directly to PyErr_SetObject().
PyErr_SetObject() expects a borrowed reference, so the string leaked.

PyString_Check() had already succeeded.

The behavior of co_varnames in the presence of nested argument tuples
