uart0 functionality is removed by #3164. This patch implements periph/uart,
rather than deprecated uart0, using /dev/tty.
To use with netdev2_tap simultaneously, this patch adds asynchronus read system
and modifies netdev2_tap to use it.
A TTY device is specified on command line with -c (COM) option, since -t was
used by the old implementation.
This patch also implements empty GPIO driver needed by the xbee driver.
The stacksizes for native were defined in a way, so that
DEBUG did not work inside of interrupt routines. The new
values should still be large enough but allow now for this.
The hwtimer_wait test was tortured with the
following script which ran several hours.
----
make clean all-debug
while :
do
date
./bin/native/hwtimer_wait.elf > log &
pid=$!
sleep 20
success=$(cat log|grep success)
if [ "$success" != "success" ]
then
date
echo "BUG"
exit
fi
kill $pid
done

Closes#715.
As discussed in #2725, this commit renames a number of stacksize constants to
better convey their intended usage. In addition, constants for thread priority
are given a `THREAD_` prefix. Changes are:
* KERNEL_CONF_STACKSIZE_PRINTF renamed to THREAD_EXTRA_STACKSIZE_PRINTF
* KERNEL_CONF_STACKSIZE_DEFAULT renamed to THREAD_STACKSIZE_DEFAULT
* KERNEL_CONF_STACKSIZE_IDLE renamed to THREAD_STACKSIZE_IDLE
* KERNEL_CONF_STACKSIZE_MAIN renamed to THREAD_STACKSIZE_MAIN
* Move thread stacksizes from kernel.h to thread.h, since the prefix changed
* PRIORITY_MIN renamed to THREAD_PRIORITY_MIN
* PRIORITY_IDLE renamed to THREAD_PRIORITY_IDLE
* PRIORITY_MAIN renamed to THREAD_PRIORITY_MAIN
* Move thread priorities from kernel.h to thread.h since the prefix has changed
* MINIMUM_STACK_SIZE renamed to THREAD_STACKSIZE_MINIMUM for consistency
Per default random data is read from `/dev/random` now.
If specified (e.g. `-s 4711`), data is generated by calls to POSIX
random function like before. The POSIX random API is initialize with
the given seed (`srandom(4711);` in this example).
