91842c3db6 Remove partially outdated CmdPreprocessor/CmdRenderer docs
These docs were slightly drifting from the user guide docs. Instead of
trying to maintain multiple copies of this, I have changed it so that
it just links out to the guide.

(The guide docs could be cleaned up a little, but that's a separate
issue.)

797112ef36 Clean up some fs-related utilities
This does a little cleanup around the usage of filesystem functions:

- Add `mdbook_core::utils::fs::read_to_string` as a wrapper around
  `std::fs::read_to_string` to provide better error messages. Use
  this wherever a file is read.
- Add `mdbook_core::utils::fs::create_dir_all` as a wrapper around
  `std::fs::create_dir_all` to provide better error messages. Use
  this wherever a file is read.
- Replace `mdbook_core::utils::fs::write_file` with `write` to mirror
  the `std::fs::write` API.
- Remove `mdbook_core::utils::fs::create_file`. It was generally not
  used anymore.
- Scrub the usage of `std::fs` to use the new wrappers. This doesn't
  remove it 100%, but it is now significantly reduced.

3629e2c051 Add an iterator over chapters
This adds the `Book::chapters` iterator (and `for_each_chapter_mut`) to
iterate over non-draft chapters. This is a common pattern I keep
encountering, and I figure it might simplify things. It runs a little
risk that callers may not be properly handling every item type, but I
think it should be ok.

3e673ce424 Switch from log to tracing
This switches to using the tracing crate instead of log. Tracing
provides a lot of nice features which we can take advantage of moving
forward.

This also adjusts the output fairly significantly. This includes:

- Switched the environment variable from RUST_LOG to MDBOOK_LOG.
- Dropped the timestamp. I experimented with various different time
  displays, but ultimately decided to omit it for now. I don't think
  I've ever found it to be useful, and it takes up a very significant
  amount of space. It could potentially be useful for basic profiling,
  but I think there are other, better mechanisms for that. We could
  consider leveraging tracing itself for doing some basic profiling
  (like using something like tracing-chrome).
- Dropped the target unless MDBOOK_LOG is set. The target tends to be
  pretty noisy, and doesn't really convey much information unless you
  are debugging or otherwise trying to adjust the log output.
- Added color.
- Slightly reworked the way the error cause trace is displayed.
- Slightly changed the way html5ever filtering is done, as well as add
  handlebars to the list since they both are very noisy. You can
  override this now by explicitly listing them as targets.

I still expect that mdbook will eventually change how it displays things
to the console, possibly switching away from tracing and printing things
itself. However, that is a larger project for the future.

235c1f87f0 Factor out handle_render_command_error
This moves `handle_render_command_error` out to the crate root so that
it can later be shared with `CmdPreprocessor`.

e7084e5548 Change CmdPreprocessor to use paths relative to the book root
This changes preprocessors so that:

- Relative paths in the `command` value are relative to the book root.
- The process current directory is the book root.

This makes it so that it isn't dependent on the directory where `mdbook`
is executed.

Fixes https://github.com/rust-lang/mdBook/issues/1424

df037d132d Remove legacy relative renderer command paths
This removes the deprecated support for renderer paths that are relative
to the destination. Relative renderer command paths now must always be
relative to the book root.

5956092b4b Switch all public types to non_exhaustive
This switches all public types to use non_exhaustive to make it easier
to make additions without a semver-breaking change.

Some of the ergonomics are hampered due to the lack of exhaustiveness
checking. Hopefully some day in the future,
non_exhaustive_omitted_patterns_lint or something like it will get
stabilized.

Closes https://github.com/rust-lang/mdBook/issues/1835

529cfc34ec Remove toml as a public dependency
This removes toml as a public dependency. This reduces the exposure of
the public API, reduces exposure of internal implementation, and makes
it easier to make semver-incompatible changes to toml.

This is accomplished through a variety of changes:

- `get` and `get_mut` are removed.
- `get_deserialized_opt` is renamed to `get`.
- Dropped the AsRef for `get_deserialized_opt` for ergonomics, since
  using an `&` for a String is not too much to ask, and the other
  generic arg needs to be specified in a fair number of situations.
- Removed deprecated `get_deserialized`.
- Dropped `TomlExt` from the public API.
- Removed `get_renderer` and `get_preprocessor` since they were trivial
  wrappers over `get`.

9b27b14985 Move built-in renderers to mdbook-driver
This is a pure git rename in order to make sure that git can follow
history. The next commit will integrate these into mdbook-driver.
