[issue6877] enable compilation of readline module on Mac OS X 10.5 and 10.6

[Zvezdan Petkovic]

The readline-libedit-2.6.5.patch is attached.

The patch was applied and python built in several configurations on Mac
OS X 10.6 (Snow Leopard).  There is no regression (details below).

Can somebody else test on Mac OS X 10.5 (Leopard)?

32-bit
======

Configuration with system libedit::

    ./configure --prefix=${HOME}/opt/snapshot/2.6.5 \
        BASECFLAGS="-arch i386" \
        CFLAGS="-arch i386" \
        LDFLAGS="-arch i386" \
        MACOSX_DEPLOYMENT_TARGET=10.6

Configuration with GNU readline 6.1::

    ./configure --prefix=${HOME}/opt/snapshot/gnurl/2.6.5 \
        BASECFLAGS="-arch i386" \
        CFLAGS="-arch i386" \
        CPPFLAGS="-I/opt/local/include" \
        LDFLAGS="-arch i386 -L/opt/local/lib" \
        MACOSX_DEPLOYMENT_TARGET=10.6

Failed tests for both builds:

- test_asynchat
- test_smtplib


64-bit
======

Configuration with system libedit::

    ./configure --prefix=${HOME}/opt/snapshot/2.6.5-64 \
        MACOSX_DEPLOYMENT_TARGET=10.6

Configuration with GNU readline 6.1::

    ./configure --prefix=${HOME}/opt/snapshot/gnurl/2.6.5-64 \
        CPPFLAGS="-I/opt/local/include" \
        LDFLAGS="-L/opt/local/lib" \
        MACOSX_DEPLOYMENT_TARGET=10.6checking

Failed tests for both builds:

- test_asynchat
- test_macostools
- test_smtplib

Unexpected skips:

- test_dl


Universal
=========

Configuration with system libedit::

    ./configure --prefix=${HOME}/opt/snapshot \
        BASECFLAGS="-arch x86_64 -arch i386" \
        CFLAGS="-arch x86_64 -arch i386" \
        LDFLAGS="-arch x86_64 -arch i386" \
        MACOSX_DEPLOYMENT_TARGET=10.6

Configuration with GNU readline 6.1::

    ./configure --prefix=${HOME}/opt/snapshot/gnurl \
        BASECFLAGS="-arch x86_64 -arch i386" \
        CFLAGS="-arch x86_64 -arch i386" \
        CPPFLAGS="-I/opt/local/include" \
        LDFLAGS="-arch x86_64 -arch i386 -L/opt/local/lib" \
        MACOSX_DEPLOYMENT_TARGET=10.6

Failed tests for both builds:

- test_asynchat
- test_macostools
- test_smtplib

Unexpected skips:

- test_dl

when run as 64-bit or 32-bit executable.

Errors in both asynchat and smtplib are caused by the same issue in
asyncore.py.  A typical error output::

    error: uncaptured python exception, closing channel
    <test.test_asynchat.echo_client at 0x1b112b0>
    (<class 'socket.error'>:[Errno 9]
     Bad file descriptor
     [/Users/zvezdan/opt/snapshot/2.6.5/lib/python2.6/asyncore.py|
      readwrite|107]
     [/Users/zvezdan/opt/snapshot/2.6.5/lib/python2.6/asyncore.py|
      handle_expt_event|441]
     [<string>|getsockopt|1]
     [/Users/zvezdan/opt/snapshot/2.6.5/lib/python2.6/socket.py|_dummy|165])

but this is not caused by readline patch.
