Removed unnecessary code from resolver.
Merge pull request #345 from oliverschmidt/master

Removed unnecessary code from resolver.
Initialize tcpip process before resolver process.

Since introduction of mDNS (https://github.com/contiki-os/contiki/commit/f145c17039b778cde1d53b6828757cd91dc8480a)
the resolver process initialization depends on the tcpip process
already being initialized (because of the call to udp_new()).

Updates CC2538 GPIO

1. Fixes two of the comments to GPIO macros. They were copied but not
updated.
2. Adds SET and CLR macros for controlling GPIO pins.

Updates to CC2538 GPIO
Optimized CS8900A driver for speed and size.

- Speed: The primary byte copy loops are reduzed to the bare minimum by adjusting the base pointer 'ptr' and loop register 'y' in such a way that the 'y' overflow matches the low byte of the loop size.

- Size: Factored out all repeated code into subroutines. Introduced a loop for setting the MAC address.

Additional minor changes:

- Activate frame reception as last step of initialization after CS8900A configuration.

- Properly set internal address bits used by the CS8900A.
- Optimized LAN91C96 driver for speed and size.

- Speed: The primary byte copy loops are reduzed to the bare minimum by adjusting the base pointer 'ptr' and loop register 'y' in such a way that the 'y' overflow matches the low byte of the loop size.

- Introduced a loop for setting the MAC address.

Additional minor fix:

- Properly start self modification with first location.
