Introduce a new option, -U, for performing memory operions. Its

argument is a 4 field string (fields seperated by colons) which
indicate what memory type to operate on, what operation to perform is
(read, write, or verify), the filename to read from, write to, or
verify against, and an optional file format field.  Multple -U options
can be specified to operate on more than one memory at a time with a
single invocation.  For example, to update both the flash and the
eeprom at the same time one can now specify the following:

	avrdude -p -e -U flash:w:main.hex:i -U eeprom:w:eeprom.hex:i
