[En-Nut-Discussion] NutMicroDelay for AVR

Hello,

I just checked in a reworked AVR NutMicroDelay version that
- doesn't need NUT_CPU_FREQ defined
- only uses divison during startup
- uses 16 bit math where possible
- tries to correct loop overhead

I can now run bitbanging One-Wire on a AT90CAN128 board with 16 MHz,
compiled with avr-gcc 4.3.3. Please check and report with other compiler
versions.

Bye
