The auto initialization of the sht1x module differs from the initialization of
other sensors, but previously no documentation pointed that out. This lack of
documentation led to a bug being introduced. This commit provides the previously
missing documentation.
- the driver for sht1x is initialized two times
- the second initialization is done only when SAUL is used, but sht1x needs
to be initialized in any case. (SAUL registration is also done there, but
only when SAUL is actually being used.)
This commit fixes both.

The hostname does not provide any additional or necessary information to
the RIOT_VERSION string. On the contrary, some might consider the hostname
as personal information, which should not be exposed unsolicitedly.
This PR sets the tranceiver in PLL_ON state to avoid corruption of the
data in the frame buffer and sets it back to the last state which the
transceiver had before changing into transmit mode after the data is
read out. This is done to avoid data corruption when `_recv(...)` is
called to retrieve the buffer size and frame buffer protection is released.

Errors flags could not clear making the i2c unusable after error.
This fix removes the error check in start so the error flags can clear and does proper checking for status bits before _bus_check.
Properly splitting the flags between netdev_ieee802154 and the at86rf2xx
driver had as side effect that the ACK REQ flag was no longer set by
default. This commit reverts the default settings by enabling it again
on startup. The current code calls the generic netdev setter to set the
flag.
Stack size is changed from 4 times the default + printf to 5 times the
default stack size. Only on the lpc2387 this reduces the resulting stack
space. the test is not rerun for the lpc2387 and is untested.
Tests are disable for the Arduino. While they "might" work, it takes
around 8 minutes to complete the tests.
The current phydat_fit implementation the following limitations:
- The API is way more complicated to use than needed
- It doesn't perform any rounding
- It uses `long` in a place where actual width (or better range) of the type
is pretty important.
This commit addresses these limitations and uses lookup-tables to reduce the
number of divisions required.
Before this commit code using it looked like this:
``` C
long values[] = { 100000, 2000000, 30000000 };
phydat_t dat = { .scale = 42, .unit = UNIT_V };
phydat_fit(&dat, values[0], 0, phydat_fit(&dat, values[1], 1, phydat_fit(&dat, values[2], 2, 0)));
```
Now it can be used like this:
``` C
int32_t values[] = { 100000, 2000000, 30000000 };
phydat_t dat = { .unit = UNIT_V, .scale = 42 };
phydat_fit(&dat, values, 3);
```
