Adds a cryptographically secure wipe function to wipe structs with
sensitive data. Works by first casting the pointer to a `volatile`
pointer to ensure that the compiler doesn't optimize the "memset" away.
Empty array uint8_t data[] is not allowed in ISO-C++. Replacement: function coap_hdr_data_ptr, which handles
the pointer arithmetic to point where hdr.data pointed
1. When the 32 bit target of the xtimer overflowed the timer was not placed in the right list.
2. When the hardware timer overflowed the comparison was wrong for setting next target.
3. Backoff condition
In RIOT native, sending CTRL+D to a shell started using shell_run would resulted in and
endless prompt loop. I've been unable to trigger such a behaviour
on actual hardware using a UART connection, but calling `pm_off` seemed
like a better alternative than having an `#ifdef BOARD_NATIVE`.

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);
```
This commit extends the fletcher16 function with a set of init, update
and finish functions to allow for multi-part checksums. This is useful
when the data that has to be checksummed is not available in a single
continuous buffer.
COAP_CT_ style defines for the content types are deprecated in favour of
COAP_FORMAT_ style defines. COAP_FORMAT_ is expanded to include any
missing content type that was available with COAP_CT_.
