The trie code looks a lot like the trie in exp/norm. It uses different
types, however.  Also, there is only a lookup for []byte and the unsafe
lookup methods have been dropped, as well as sparse mode.
There is now a method for generating a trie. To output Go code, one now needs
to first generate a trie and then call print() on it.

(See http://www.unicode.org/reports/tr10/#Contractions.)  Each rune that is at the
start of any contraction is associated a trie. This trie, in turn, may be shared
by other runes that have the same set of suffixes.

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.

The reverseproxy test depended on the behavior of
runtime.NumGoroutines(), which makes no guarantee when
goroutines are reaped. Instead, modify the flushLoop()

of gorountines running.
