98c5ceb73f ptp: On Windows handle socket polls that result in no error but also no FD_READ event 
According to the documentation this should never happen but apparently
does under certain circumstances. As the sockets are set non-blocking,
trying to read from them regardless should not cause any problems.

In all cases that were observed so far, the socket in question actually
has a packet queued up for reading.

fa8fbab0f7 ptp: Parse PTP messages in the helper process and filter earlier 
This drops invalid, unknown or uninteresting PTP messages in the helper
process already instead of forwarding them to the main process.

b76f9c8392 ptp: Capture actual send/receive times in the helper process 
While this doesn't yet use any OS provided times from the actual network
stack, this still gets rid of any IPC jitter between the helper process
and the main process as part of the PTP time calculations and should
improve accuracy.

d55492add4 ptp: Fix compilation with Rust 1.48 
Use `ErrorKind::NotFound` instead of `ErrorKind::Unsupported` if the
`getrandom` syscall is not available. `Unsupported` was added in 1.53.

0219b6f6fa ptp-helper: Add some tests for functionality and memory safety of unsafe code 
These tests are mostly for ensuring that the calls to system APIs are
done correctly and that there are no memory bugs (that would be caught
by valgrind) in the unsafe code.

compiler error at a later time.

3fdfcdf2f6 ptp-helper: Rewrite in Rust for portability and security 
This works on Linux, Android, Windows, macOS, FreeBSD, NetBSD, OpenBSD,
DragonFlyBSD, Solaris and Illumos.
Newly supported compared to the C version is Windows.

Compared to the C version various error paths are handled more correctly
and a couple of memory leaks are fixed. Otherwise it should work identically.

The minimum required Rust version for compiling this is 1.48, i.e. the
version currently in Debian stable. On Windows, Rust 1.54 is needed at
least.
