disabled level warning: say which create the message refers to #2285

I just saw this warning when trying to debug something in Miri:

warning: some trace filter directives would enable traces that are disabled statically
 | `miri::tls=trace` would enable the TRACE level for the `miri::tls` target
 = note: the static max level is `info`
 = help: to enable DEBUG logging, remove the `max_level_info` feature

I spent 10min figuring out why the log crate is doing this (Miri is using env-logger for logging), until I realized that this error actually originates from inside rustc, which I guess uses tracing. It would have helped if the error message would say which crate is even talking to me here. :)

thanks for the PR, this is definitely clearer!

i wonder if we should also add something indicating that this warning was emitted by tracing_subscriber::EnvFilter somewhere? maybe in this line:

warn("some trace filter directives would enable traces that are disabled statically");

but that can be done in a follow-up.

Yeah feel free to edit the message -- I have never used this crate, so I don't even know what tracing_subscriber::EnvFilter is.^^

# 0.3.16 (October 6, 2022)

This release of `tracing-subscriber` fixes a regression introduced in
[v0.3.15][subscriber-0.3.15] where `Option::None`'s `Layer`
implementation would set the max level hint to `OFF`. In addition, it
adds several new APIs, including the `Filter::event_enabled` method for
filtering events based on fields values, and the ability to log internal
errors that occur when writing a log line.

This release also replaces the dependency on the unmaintained
[`ansi-term`] crate with the [`nu-ansi-term`] crate, resolving an
*informational* security advisory ([RUSTSEC-2021-0139] for
[`ansi-term`]'s maintainance status. This increases the minimum
supported Rust version (MSRV) to Rust 1.50+, although the crate should
still compile for the previous MSRV of Rust 1.49+ when the `ansi`
feature is not enabled.

### Fixed

- **layer**: `Option::None`'s `Layer` impl always setting the
  `max_level_hint` to `LevelFilter::OFF` (#2321)
- Compilation with `-Z minimal versions` (#2246)
- **env-filter**: Clarify that disabled level warnings are emitted by
  `tracing-subscriber` (#2285)

### Added

- **fmt**: Log internal errors to `stderr` if writing a log line fails
  (#2102)
- **fmt**: `FmtLayer::log_internal_errors` and
  `FmtSubscriber::log_internal_errors` methods for configuring whether
  internal writer errors are printed to `stderr` (#2102)
- **fmt**: `#[must_use]` attributes on builders to warn if a
  `Subscriber` is configured but not set as the default subscriber
  (#2239)
- **filter**: `Filter::event_enabled` method for filtering an event
  based on its fields (#2245, #2251)
- **filter**: `Targets::default_level` accessor (#2242)

### Changed

- **ansi**: Replaced dependency on unmaintained `ansi-term` crate with
  `nu-ansi-term` ((#2287, fixes informational advisory
  [RUSTSEC-2021-0139])
- `tracing-core`: updated to [0.1.30][core-0.1.30]
- Minimum Supported Rust Version (MSRV) increased to Rust 1.50+ (when
  the `ansi`) feature flag is enabled (#2287)

### Documented

- **fmt**: Correct inaccuracies in `fmt::init` documentation (#2224)
- **filter**: Fix incorrect doc link in `filter::Not` combinator
  (#2249)
