tracing: prepare to release 0.1.30

# 0.1.30 (February 3rd, 2021)

This release adds *experimental* support for recording structured field
values using the [`valuable`] crate. See [this blog post][post] for
details on `valuable`.

Note that `valuable` support currently requires `--cfg
tracing_unstable`. See the documentation for details.

This release also adds a new `enabled!` macro for testing if a span or
event would be enabled.

### Added

- **field**: Experimental support for recording field values using the
  [`valuable`] crate ([#1608], [#1888], [#1887])
- `enabled!` macro for testing if a span or event is enabled ([#1882])

### Changed

- `tracing-core`: updated to [0.1.22][core-0.1.22]
- `tracing-attributes`: updated to [0.1.19][attributes-0.1.19]

### Fixed

- **log**: Fixed "use of moved value" compiler error when the "log"
  feature is enabled ([#1823])
- Fixed macro hygiene issues when used in a crate that defines its own
  `concat!` macro ([#1842])
- A very large number of documentation fixes and improvements.
