Revert "net.c: Adding read and write timeouts to the tcp open. One site was connecting but then failing to send a response and hanging indefinitely."

This reverts commit b1daa872c111d286d607213ce0ba97d74133b9dd.

Although the relatively short 10 second read/write timeout works for bigDataUrl connections,
it does not work for robots accessing html sites that can take a long time to return a response.
This approach was too simple.  It is being reverted.

Steve found a joinerCheck error about a duplicate ID in rn4.rgdQtl.
Comments in doc/rn4.txt indicated that the dupe should have been
resolved, but somehow the database tables on hgwdev did not reflect
the fix.  So I followed the same steps in rn4.txt to fix the dupe,
and the joinerCheck error is resolved on hgwdev.
