The thread callback is called when defined and a thread is started and when the thread is exiting.

Closes #130 & #131

-Change check to actually check for disconn_cb instead of arg, to prevent null pointer derefence.
-Change behaviour to only fire disconnect CB when a peer has a parent, to be in line with documentation.

The header librist_srp.h did not contain an 'extern C' directive.
Using rist_enable_eap_srp() from C++ applications resulted in mangled
names and undefined symbols. This commit cleans up 'extern C' in a
consistent way in all headers: move all #include outside 'extern C'
and protect all declarations in all headers using 'extern C'.

Cleanup, and simplify control flow

Log the RTP sequence number instead of the buffer sequence number, as that makes more sense.

While the fix was correct it lead to peers not being selected due to the fact
that the weight of it's children where also added to the total.
To fix:
- don't add the weight of children to the total weight, since we select based on parent
- don't add the weight of a listening peer to the total, until it has at least one child.

Closes #120

rist_start rist_destroy and rist_peer_create & destroy are for both sender & receiver, update documentation to reflect that.
Fixes #124

The pthread wrapper for Windows compiled on 64-bit, not on 32-bit Windows.

Compilation of librist failed on Windows with Visual Studio 2019.

Move flow shutdown before lock to fix rare locking issue where lock never gets acquired while output thread
keeps locking/unlocking.

Restarting a rist2rist source sometimes causes the receiver
connected to rist2rist to break because it never recalculates
the time offset.
Reset the flow if we go over a late packets threshhold.

If not, pkg-config produces a file that contains a full path
to libwinpthread.a
