Increment major version
...
Make a major version bump since the clockstretching changes require
retries/polling and might break current master implementations.

Do not use IRQs and remove vector table
...
Do not use ISRs and poll for interrupt flags in the main loop.
No need for moving vector table into bootloader and back.
Remove vector table by adding LDFLAGS = -nostartfiles.
Manually add some code which is now removed, but still needed by C
runtime:
- make sure that r1 is 0x00 (zero register).
- on some MCUs the stack pointer is not initialized correctly after
reset.
- main() need to be placed in special section .init9 to be called at all.
Not sure why the BSS and DATA segment are still initialized.
This change is heavily based on the optiboot bootloader.

Simplify ACK handling
...
TWEA bit in TWCR register needs to be cleared to send NACK.
Clear it when too many bytes were received, re-enable it after
when going idle.
Add missing state for prev. send NACK.
Catch all invalid states and reset bus.
TWINT bit needs to be set every time in ISR.

Fix sizeof(VERSION_STRING)
...
- sizeof(info) should not be increased (16->18) since the size is never
exchanged with the I2C master. Also using a non 2^x size will result
in bigger code since the compiler can no longer use a simple AND to
implement the bcnt %= sizeof(info).
- when using a info[16] the firmware is small enough to fit in a 512
word bootloader again :)
