This branch makes a few small README and Cargo.toml changes:
* Add Azure Pipelines build status badges to Cargo.tomls
* Change README build status badges to Azure Pipelines
* Add "maintenance: experimental" badges to unreleased crates
* Link to `tracing` docs and crates.io page in the root README,
rather than `tracing-core`.

Now that `tracing` 0.1.3 is released, this branch removes path
dependencies on `tracing` from other crates in the repo.

## Motivation
`tracing-core` 0.1.2 deprecated the `Subscriber::drop_span` function in
favour of `try_close`.
## Solution
This branch updates all other crates to depend on core 0.1.2, and
replaces uses of `drop_span` with `try_close`.

### Added
- `Span::none()` constructor, which does not require metadata and
returns a completely empty span (#147).
- `Span::current()` function, returning the current span if it is
known to the subscriber (#148).
### Fixed
- Broken macro imports when used prefixed with `tracing::` (#152).

This PR changes the field names to better represent the `is_span` and
`is_event` values being serialized in `Metadata`. Out of band, we noticed the
previous field names did not correspond with the data we were serializing
for those 2 functions.
## Motivation
#122 updated all crates to use Rust 2018 syntax, but I neglected to add
`edition = "2018"` to the `Cargo.toml`s.
## Solution
This fixes that.

See #95
This branch renames everything from `tokio-trace` to `tracing`.
Unlike PR #98, the nursery crates still depend on the crates.io
versions of `tokio-trace` and `tokio-trace-core`, but renamed
to `tracing`/`tracing-core` in `Cargo.toml`. We can update the
nursery crates to depend on local path dependencies in a
subsequent PR, as that will require making code changes to the
nursery crates.
This branch _also_ updates the minimum Rust version to 1.34.0,
to the shock and horror of the millions of `tracing` users still
on Rust 1.26.0. This was necessary in order to allow renaming
crates in `Cargo.toml`, and to resolve that not using the `dyn`
keyword is now a warning on nightly.
