To avoid additional packet memory allocation and copy when sending or
receiving packets, this commit introduces additional available space
before and after layer 3 IPv4 or IPv6 packet in the Wintun rings. Wintun
will ignore data in those areas.

api: elevate to SYSTEM in WintunEnumAdapters()2021-03-08T12:48:29ZSimon Rozmansimon@rozman.si2021-03-08T12:48:29Zurn:sha1:cef79225560bd454cb5c49d8d2b0cfac869de8d3
The WintunEnumAdapters() requires namespace mutex. However,
NamespaceTakePoolMutex() works as SYSTEM user only.
WireGuard is using the WintunEnumAdapters() in its manager service to
cleanup stale adapters. As the WireGuard manager service is running as
SYSTEM, this requirement was not apparent before.
This commit also extends the example project to list its existing
adapters at start.

Discourage use of kernel interface, which gives us more flexibility if
we ever want to change it.

Wintun*Allocate*SendPacket -> WintunSendPacket

This makes our intentions a lot more clear, and in case we ever add
other version functions, makes the forward path simpler.
