errors: catch urllib errors specifically instead of using safehasattr()...

errors: catch urllib errors specifically instead of using safehasattr() Before this patch, we would catch `IOError` and `OSError` and check if the instance had a `.code` member (indicates `HTTPError`) or a `.reason` member (indicates the more generic `URLError`). It seems to me that can simply catch those exception specifically instead, so that's what this code does. The existing code is from (commands: report http exceptions nicely, 2005-06-17), so I suspect it's just that there was no `urllib2` (where `URLError` lives) back then. The old code mentioned `SSLError` in a comment. The new code does *not* try to catch that. The documentation for `ssl.SSLError` says that it has a `.reason` property, but `python -c 'import ssl; print(dir(ssl.SSLError("foo", Exception("bar"))))` doesn't mention that property on either Python 2 or Python 3 on my system. It also seems that `sslutil` is pretty careful about converting `ssl.SSLError` to `error.Abort`. It also is carefult to not assume that instances of the exception have a `.reason`. So I at least don't want to catch `ssl.SSLError` and handle it the same way as `URLError` because that would likely result in a crash. I also wonder if we don't need to handle it at all (because `sslutil` might handle all the cases). It's now early in the release cycle, so perhaps we can just see how it goes?

      #

      # Instruction:

      # -----------

      # Run this script to generate the tcsh source file, and source
