Added

The minimum supported Rust version is now defined as 1.70. Previously it was undefined.
Wrappers for std::sync primitives can now be const constructed.
Add support for std::sync::OnceLock
Added backtraces of mutex allocations to the cycle report. Capturing backtraces does incur some overhead, this can be mitigated by disabling the backtraces feature which is enabled by default.

Breaking

Update parking_lot dependency to 0.12.
Restructured the crate to reduce typename verbosity. Wrapper names now match the name of the primitive they wrap. Specific always/debug tracing versions have now moved to separate modules. For example, tracing_mutex::stdsync::TracingMutex is now tracing_mutex::stdsync::tracing::Mutex, and tracing_mutex::stdsync::DebugMutex is now called tracing_mutex::stdsync::Mutex. This hopefully reduces the visual noise while reading code that uses this in practice. Unwrapped primitives are reexported under tracing_mutex::stdsync::raw for convenience.

Fixed

Enforce that all internal mutex guards are !Send. They already should be according to other reasons, but this adds extra security through the type system.
