There were two issues:
1) It might not be a path error, it might be 'permission denied'.
2) The concept of $PATH is Unix-specific.

The LDREXD and STREXD instructions require
aligned addresses, and the ARM stack is not
guaranteed to be aligned during the check.
This may cause other problems later (on the ARM
not all 64-bit pointers may be 64-bit aligned)
but at least the check is correct now.

Programs expect that Read and Write are synchronous.
The background goroutines make the implementation
a little easier, but they introduce asynchrony that
trips up calling code. Remove them.

This changes the internal implementation of Cond so that
it uses two generations of waiters. This enables Signal
to guarantee that it will only wake up waiters that are
currently sleeping at the call time.
Fixes#1648.

This removes exec.Run and replaces exec.Cmd with a
new implementation. The new exec.Cmd represents
both a currently-running command and also a command
being prepared. It has a good zero value.
You can Start + Wait on a Cmd, or simply Run it.
Start (and Run) deal with copying stdout, stdin,
and stderr between the Cmd's io.Readers and
io.Writers.
There are convenience methods to capture a command's
stdout and/or stderr.

- 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.

Also make CaseRange uint32s rather than ints, so if we go to
64-bit ints we don't waste more space.

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.
Fixes#1884.
