Add initial support for the Atmel STK600, for

"classic" AVRs (AT90, ATtiny, ATmega) in both,
ISP and high-voltage programming modes.
* Makefile.am: Add -lm.
* avrdude.conf.in: Add stk600, stk600pp, and stk600hvsp.
* config_gram.y: Add support for the stk600* keywords.
* lexer.l: (Ditto.)
* pgm.h: Add the "chan" parameter to set_varef().
* stk500.c: (Ditto.)
* serial.h: Add USB endpoint support to struct filedescriptor.
* stk500v2.c: Implement the meat of the STK600 support.
* stk500v2.h: Add new prototypes for stk600*() programmers.
* stk500v2_private.h: Add new constants used in the STK600.
* term.c: Add AREF channel support.
* usb_libusb.c: Automatically determine the correct write
endpoint ID, the STK600 uses 0x83 while all other tools use
0x82.  Propagate the EP to use through struct filedescriptor.
* usbdevs.h: Add the STK600 USB product ID.
* tools/get-stk600-cards.xsl: XSL transformation for
targetboards.xml to obtain the list of socket and routing
card IDs, to be used in stk500v2.c (for displaying the
names).
* tools/get-stk600-devices.xsl: XSL transformation for
targetboards.xml to obtain the table of socket/routing cards
and their respective AVR device support for doc/avrdude.texi.
* avrdude.1: Document all the STK600 stuff.
* doc/avrdude.texi: Ditto.  Added a new chapter for
Programmer Specific Information.

Thanks to Eirik Rasmussen from Atmel Norway for his support in
getting this code running within that short amount of time!
