- better number scanning algorithm
- fixed a couple of bugs related to base interpretation
- added scan benchmark
- added more test cases and made tests more precise
- introduced Int.scan method matching nat.scan
- refactored Int.Scan; now uses int.scan
- refactored Int.SetString; now uses int.scan

There is more potential, this was a fairly simple change.

Using the getaddrinfo order is only okay if we
are smart enough to try multiple addresses in Dial.
Since the code does not do that, we must make
the right first choice, regardless of what getaddrinfo
does, and more often that not that means using the
IPv4 address, even on IPv6 systems.  With the CL
applied, gotest fails in package net on OS X.

net: name-based destination address selection

getaddrinfo() orders the addresses according to RFC 3484.

This means when IPv6 is working on a host we get results like:
    []string = {"2001:4810::110", "66.117.47.214"}

and when it's not working we get:
    []string = {"66.117.47.214", "2001:4810::110"}

thus can drop firstFavoriteAddr.

This also means /etc/gai.conf works on relevant systems.

This mostly adds the infrastructure for writing various forms of
packets as well as reading them. Adding symmetric encryption support
was simply an easy motivation.

There's also one brown-paper-bag fix in here. Previously I had the
conditional for the MDC hash check backwards: the code was checking
that the hash was *incorrect*. This was neatly counteracted by another
bug: it was hashing the ciphertext of the OCFB prefix, not the
plaintext.

flate's reader greedily reads from the shared io.Reader in Framer. This leads to a data race on Framer.r. Fix this by providing a corkedReader to zlib.NewReaderDict(). We uncork the reader and allow it to read the number of bytes in the compressed payload.

On windows, the command line is passed as a single null-terminated string. While the automatic parameter escaping done by syscall.StartProcess works fine with most Windows programs, some applications do their own custom parsing of the command line, in which case the automatic escaping becomes harmful.
This CL adds a new extra CmdLine field to syscall.ProcAttr that will be used as the raw/unescaped command line if not empty.

When I was first coding Abs, I wondered if people wouldn't
expect the path to be consistently clean, even if the path
passed in was already absolute.

CL 4524078 has a potential problem based on exactly that
assumption, so it feels like this behavior is indeed the
most useful and least surprising.

By splitting the ranges into 16-bit values and 32-bit values,
we can reduce about 3000 entries by 48 bits per entry, or about
