Refactor clock_gettime support for Darwin to fix compilation problems for older OSes

Previous method was written only our MinGW setup in mind.
This corrects build failures due to missing cmake toolchainfile, which may not be needed for other builds (as tested with provided aarch64 cross file).
Meson >= 0.56.0 correctly generates the cmake toolchain file (and documentation explicitly states not to set this option manually), so there it is not used
The toolchain variable has been renamed to make more sense when used in other arches, and in a way that it should not clash with any meson native options.

Add peer authentication callback (missing on sender when it initates the connection and on the receiver when it initates the connection)

Unfortunately this is really necessary so late in the release process. The previous design being able to free data from under a calling application.

Fix retry_dequeue loop. We were counting errors as processed nacks and it would cause the queue to grow out of control under high packet loss.

Add stats for sender max bandwidth skips and provide max bandwidth protection for congestion control off mode.

When we receive a echo request we (correctly) assume receiver supports echo requests, and disable RTT calculation via SR-RR packets, however we don't start sending echo requests, this corrects that so we do send them.

Use the correct dynamic rtt for retries on sender and change agressive congestion control to allow more retries (2*RTT spacing on them)
