[avr-libc-dev] Better Interrupt Macro

[Dean]

I've finished converting my "better" ISR macro over to the style used in 
AVRLibC. I added in one or two extra things from last time, and added in the 
sei(), cli(), EMPTY_INTERRUPT and deprecated SIGNAL macros/functions from the 
old interrupt.h file.

I added in new DoxyGen comments, however as I have no idea how to get DoxyGen 
to run, I can't test this. If someone would be so kind as to do so, I'd 
appreciate it as I'm only guessing on the correct syntax to use by looking at 
other AVRLibC header files.

I don't know if attachments are allowed, so I'll upload it to my private 
webserver:
          http://home.pacific.net.au/~sthelena/General/interrupt_new.h

What is the appropriate channel to use to get this into the next AVRLibC? Do I 
submit it as a new patch?

Cheers all,
- Dean
