[patch] Support New NIO in IcedTea

[C. K. Jester-Young]

I'm working on a patch for the latest changes for both NIO2 and IcedTea
(though in the long run, after a discussion with Alan Bateman, I've
decided it'd be a better idea to implement support for IcedTea to check
out specific tags of NIO2, just as is done with the jdk7 forest), so
I'll write again once I have something working, but meanwhile, I should
respond to this. :-)

Haha, that reminded me of my Google onsite interview half a year ago,
where I was asked what I felt could be improved with Google products.
I had my fair list of things too. :-)

Gmail's IMAP access is, as far as I know, SSL-required (port 143 is
inaccessible). I have these settings in Mutt, which you're most welcome
to adapt as required:

set spoolfile="imaps://cky944%40gmail.com@imap.gmail.com/"
set smtp_url="smtps://cky944%40gmail.com@smtp.gmail.com/"
unset record	# since Gmail saves your mail when sent via their SMTP
subscribe distro-pkg-dev at openjdk.java.net
# ...plus similar subscribe lines for other mailing lists I'm on

Remember to enable IMAP access in your Gmail account settings, or else
you won't be able to log in. :-)

As far as I know, IcedTea _does_ use the system ecj when compiling; if
it weren't so, it'd be trivial to use a newer version that supported
@Override annotations in interface methods, for instance.

Oh, you're talking about the ecj shell script, not ecj.jar. Well, it
should be easy for you to copy the shell script into javac.in before
you build. :-)

I haven't heard any feedback during my time away, so I gathered it may
not have been working too well. Oh well. Hopefully the upcoming patches
will work better. :-)
