Don't foster-parent text nodes that consist only of whitespace.
(I implemented this entirely in inTableIM instead of creating an
inTableTextIM, because the sole purpose of inTableTextIM seems to be
to combine character tokens into a string, which our tokenizer does
already.)

Use parseImpliedToken to clarify a couple of cases.

Handle <style>, <script>, <input>, and <form>.

Ignore doctype tokens.

If a part ends with "--boundary--", without a final "\r\n",
that's also a graceful EOF, and we should return io.EOF instead
of the fmt-wrapped io.EOF from bufio.Reader.ReadSlice.

This changes the misc/dist program to generate OS X
packages using pkgbuild and productbuild.

The productbuild utility makes it easy to generate
packages with a custom Distribution file.  This allows
us to add an installcheck script that presents a
friendly message to users who are running on an old
version of Mac OS X.

The change also fixes a few issues with the
postinstall script:

 - In-repo version of the script has been made
   executable. Installers generated using the new
   tools couldn't execute it otherwise.

 - It now uses -d for checking for the existence
   of the Xcode specs directory.

 - The call to sudo.bash has been dropped since cov
   and prof aren't bundled with the binary
   distributions.

Fixes #3455.

Applied the suggested fix from rsc. If the connection
is in closing state then errClosing will bubble up to

The fix has been applied to udp, ip and unix as well as

tests are available in the linked issue that verified
the bug existed there as well.

The reverseproxy test depended on the behavior of
runtime.NumGoroutines(), which makes no guarantee when
goroutines are reaped. Instead, modify the flushLoop()
to invoke a callback when it returns, so the exit
from the loop can be tested, instead of the number
of gorountines running.

When FlushInterval is specified on ReverseProxy, the ResponseWriter is
wrapped with a maxLatencyWriter that periodically flushes in a
goroutine. That goroutine was not being cleaned up at the end of the
request. This resulted in a panic when Flush() was being called on a
ResponseWriter that was closed.

The code was updated to always send the done message to the flushLoop()
goroutine after copying the body. Futhermore, the code was refactored to
allow the test to verify the maxLatencyWriter behavior.
