tracing-core 0.1.25

This release adds additional Value implementations for std::error::Error
trait objects with auto trait bounds (Send and Sync), as Rust will not
auto-coerce trait objects. Additionally, it fixes a bug when setting scoped
dispatchers that was introduced in the previous release (v0.1.24).

Added

• Value implementations for dyn Error + Send + 'static, dyn Error + Send + Sync + 'static, dyn Error + Sync + 'static (#2066)

Fixed

• Failure to use the global default dispatcher if a thread has set a scoped
  default prior to setting the global default, and unset the scoped default
  after setting the global default (#2065)
