I agree.   Here's what I propose:

1. We don't touch `socket.type`.  We don't know what kind of code exists out there and in what ways it will break.  The ship has sailed to fix it.

2. We add `socket.SOCK_TYPE_MASK` (on Linux).

3. We fix `socket.__repr__` to correctly render type.  Currently:

    >>> s = socket.socket(socket.AF_INET, socket.SOCK_STREAM | socket.SOCK_NONBLOCK)
    >>> s
    <socket.socket fd=3, family=AddressFamily.AF_INET, type=2049, proto=0, laddr=('0.0.0.0', 0)>

What I want to see:

    <socket.socket fd=3, family=AddressFamily.AF_INET, type=SOCK_STREAM | SOCK_NONBLOCK, proto=0, laddr=('0.0.0.0', 0)>

4. We add `socket.true_type` which will apply `SOCK_TYPE_MASK` and return a socket type that's safe to compare to `socket.SOCK_*` constants.

Thoughts?
