633d9b5aea nrf: keep advertisement payload alive
The memory from the advertisement payload must be kept alive until the
advertisement is stopped. Therefore, it is not allowed to use a local
variable for it. Instead, it is now part of the defaultAdvertisement
global which of course is alive as long as the program runs.

nrf52: use low-frequency crystal oscillator when available
I couldn't measure a difference in my setup, apparently my multimeter is
not able to handle the high-to-low current transition when entering
sleep mode. But it _should_ reduce current consumption a little bit.

linux: include IsRandom bit in Address type
Unlike what I previously thought, BlueZ does expose it. Unfortunately it
doesn't seem to respect it: the bit is not included in D-Bus paths.

Windows also supports the bit, which I hope to fix in a future commit.
Like BlueZ, it appears to ignore it when connecting to a device.

examples/nusserver: refactor terminal handling
The over-the-air newline format has been changed to LF always, for
simplicity. We might have used CR instead but LF works, and is the
newline format normally used on Unix (in files and stdio, except for raw
terminals).

all: change advertisement interval type
Use a new Duration type, which is used throughout the BLE stack for
durations. The resolutions are sometimes different (connection
parameters have half the resolution) but overall it should improve the
ease of use of this type.

This commit also provides a default advertisement interval that is
recommended by Apple (which I think is as good as any recommendation).
This might help to speed up discovery by Apple (and Android?) phones.

all: support HasServiceUUID on advertisement payloads
I have intentionally chosen to implement HasServiceUUID() and not
ServiceUUIDs() because returning a slice of UUIDs will likely cause a
heap allocation. And perhaps the most common use may be checking whether
a packet has a particular UUID, so no list is necessary. Getting the
full list can of course be implemented in the future, if needed.

This makes the API a bit more natural and (if needed) allows for a

all: fix bug that caused a copied DefaultAdapter
The DefaultAdapter was a regular value, not a pointer-to-struct. This
meant that simply copying bluetooth.DefaultAdapter caused a copy of the
object itself (instead of a copy of the reference, as intended). This
meant that write events did not arrive.
