tracing: prepare to release v0.1.37

[hawkw]

0.1.37 (October 6, 2022)

This release of tracing incorporates changes from tracing-core
v0.1.30 and tracing-attributes v0.1.23,
including the new Subscriber::on_register_dispatch method for
performing late initialization after a Subscriber is registered as a
Dispatch, and bugfixes for the #[instrument] attribute.
Additionally, it fixes instances of the bare_trait_objects lint, which
is now a warning on tracing's MSRV and will become an error in the
next edition.

Fixed

• attributes: Incorrect handling of inner attributes in
  #[instrument]ed functions (attributes: fix handling of inner attributes #2307)
• attributes: Incorrect location of compiler diagnostic spans
  generated for type errors in #[instrument]ed async fns (Add fake return to improve span on type error in tracing::instrument #2270)
• attributes: Updated syn dependency to fix compilation with -Z minimal-versions (fix minimal-versions correctness (v0.1.x) #2246)
• bare_trait_objects warning in valueset! macro expansion (macros: Add dyn keyword for trait objects in valueset! expansion #2308)

Added

• core: Subscriber::on_register_dispatch method (tracing-core, tracing-subscriber: Add {Collect,Subscriber}::on_register_dispatch #2269)
• core: WeakDispatch type and Dispatch::downgrade() function
  (tracing-core: Add Dispatch::downgrade() and WeakDispatch #2293)

Changed

• tracing-core: updated to 0.1.30
• tracing-attributes: updated to 0.1.23
