Oliver Jowett a2f49f2bb8 Fix a crash when an outbound client is closed in response to reading a remote message. 
When we read from some client A, we may end up forwarding a message to other
clients. If we forward to some client B and there is a write error, then
we close B and remove it from the client list. However, if before this happened
A->next == B, then the read loop will still be holding on to a pointer to B,
and we crash.

As it's unpredictable what clients could be closed at what point, the simplest
approach is to retain closed clients in the list until we are at a point where
we know there are no stray pointers on stack, and only then modify the list.
This also simplifies anything that has to loop over clients, as it doesn't need
to worry about the current client being freed under it.

Oliver Jowett 15f3408d8e Always emit a message reception time, as otherwise the FR24 uploader is unhappy. 
When we don't have a time available (e.g. remote message) use the system time.

Oliver Jowett a513c3677b Detect client EOF properly. Handle EWOULDBLOCK. 
Client disconnection appears as a read of 0 bytes.
Without a test for this, dump1090 continues to poll that client forever.

Also, read() may return EWOULDBLOCK as well as EAGAIN
for "no data right now", so handle that.

I don't know if there is an equivalent Win32 bug here as the Win32
interfaces seem subtly different to vanilla POSIX.

The following test/break can probably be removed if Win32 needs
the same fix.

Oliver Jowett c11eca44bb Try all phases if --oversample --phase-enhance is on. 
If we demodulate a message in 2.4MHz mode and it has a bad, uncorrectable CRC,
and --phase-enhance is on, then retry with the other possible phases until
we get a good CRC or run out of phases to try.

This is very expensive in AGC mode (lots of candidates that are not real
messages) but relatively cheap otherwise. It yields another 10% messages.

Also factor out some common stats code to avoid lots more copy/paste.

Malcolm Robb e3bbf7b266 Read Files are binary 
When replaying recordings, the read files are binary, so the file open
needs to reflect this so that spurious end of file characters aren't
misinterpreted.

Oliver Jowett 4732ad3498 Performance tweaking for AGC. 
Apparently enabling AGC produces samples with quite different characteristics,
and ends up eating a lot more CPU as the previous heuristics would generate a
lot of false positives. Tweaking the parameters and a bit of optimization
seems to bring this back down to usable levels without losing many potential
messages.
