This is a relatively significant edit that brings the Arduino copy of

optiboot up-to-date with the optiboot source repository as of Jun-2011
(the last changes made in the optiboot repository were in Oct-2010)

This adds support for several plaforms, fixes the "30k bug", and
refactors the source to have separate stk500.h, boot.h, and pin_defs.h

These are the arduino opticode issues fixed:
http://code.google.com/p/arduino/issues/detail?id=380
    optiboot has problems upload sketches bigger than 30 KB
http://code.google.com/p/arduino/issues/detail?id=556
    update optiboot to the point of the latest optiboot project sources.

These are issues that had been solved in the optiboot source aready:
http://code.google.com/p/arduino/issues/detail?id=364
   optiboot leaves timer1 configured when starting app, breaks PWM on
   pin 9 and 10.  (fixed with a workaround in arduino core.)
   aka http://code.google.com/p/optiboot/source/detail?r=c778fbe72df6ac13ef730c25283358c3c970f73e
   Support for ATmega8 and mega88.
   Fix fuse settings for mega168 _ISP targets
   Additional new platforms (mega, sanguino)

http://code.google.com/p/optiboot/issues/detail?id=26
   Set R1 to 0  (already in arduino code)
http://code.google.com/p/optiboot/issues/detail?id=36&can=1
   Fails to build correctly for mega88

After this commit, the only differences between the Arduino optiboot.c
and the optiboot repository optiboot.c are cosmetic.

+    \code
+    #include <avr/io.h>
+    #include <avr/boot.h>
+    \endcode
+
+    The macros in this module provide a C language interface to the
+    bootloader support functionality of certain AVR processors. These
+    macros are designed to work with all sizes of flash memory.
+
+    Global interrupts are not automatically disabled for these macros. It
+    is left up to the programmer to do this. See the code example below. 
+    Also see the processor datasheet for caveats on having global interrupts 
+    enabled during writing of the Flash.
+
+    \note Not all AVR processors provide bootloader support. See your
+    processor datasheet to see if it provides bootloader support.
+
+    \todo From email with Marek: On smaller devices (all except ATmega64/128),
+    __SPM_REG is in the I/O space, accessible with the shorter "in" and "out"
+    instructions - since the boot loader has a limited size, this could be an
+    important optimization.
+
+    \par API Usage Example
+    The following code shows typical usage of the boot API.

+    #include <avr/interrupt.h>
+    #include <avr/pgmspace.h>

+
+        // Disable interrupts.
+
+        sreg = SREG;
+        cli();
+    
+        eeprom_busy_wait ();
+
+        boot_page_erase (page);
+        boot_spm_busy_wait ();      // Wait until the memory is erased.
+
+        for (i=0; i<SPM_PAGESIZE; i+=2)
+        {
+            // Set up little-endian word.
+
+            uint16_t w = *buf++;
+            w += (*buf++) << 8;
+        
+            boot_page_fill (page + i, w);
+        }
+
+        boot_page_write (page);     // Store buffer in flash page.
+        boot_spm_busy_wait();       // Wait until the memory is written.
