There's a regression caused by recent refactor work, as it used to execute preprocessors/backends in a deterministic way, but now this is not the case, which causes trouble when some backends implicitly depend on the result from another backend and happen to work (e.g. mdbook-pdf). The root cause is that a HashMap has no order, so this PR switches this into `BTreeMap` instead.

This changes `with_renderer` and `with_preprocessor` to replace any
extensions of the same name instead of just appending to the list. This
is necessary for rust-lang's build process, because we replace the
preprocessors with local ones. Previously, mdbook would just print an
error, but continue working. With the change that preprocessors are no
longer optional by default, it is now required that we have a way to
replace the existing entries.
This changes the serialization so that `book.src` is not serialized if
it is the default. This removes the somewhat pointless `src = "src"`
which shows up in the default `mdbook init` output. Deserialization
should still default to `"src"`.
This adds the `optional` field to the preprocessor configuration to
mirror the same option for the `output` table. Missing preprocessors are
now an error unless the `optional` field is set. This should help with
inadvertently building a book when a missing preprocessor that you
expect to be installed.
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.

This replaces the `{{#previous}}` and `{{#next}}` handelbars helpers
with simple objects that contain the previous and next values. These
helpers have been a bit fussy to work with and have caused issues in the
past. This drops a large amount of somewhat fragile code with something
that is a bit simpler.
Additionally, this switches the previous/next arrows to use an `{{#if}}`
instead CSS trickery which may help with upcoming changes to
font-awesome.
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.
This removes the deprecated `output.html.copy-fonts` option. This was
deprecated in https://github.com/rust-lang/mdBook/pull/1987. The
behavior now is that the default fonts are copied over unless there is a
custom `theme/fonts/fonts.css` file.
This changes it so that it is an error if there is ever an unknown
configuration field. This is intended to help avoid things like typos,
or using an outdated version of mdbook. Although it is possible that new
fields could potentially safely be ignored, setting up a warning system
is a bit more of a hassle. I don't think mdbook needs to have the same
kind of multi-version support as something like cargo does. However, if
this ends up being too much of a pain point, we can try to add a warning
system instead.
There are a variety of changes here:
- The top-level config namespace is now closed so that it only accepts
the keys defined in `Config`.
- All config tables now reject unknown fields.
- Added `Config::outputs` and `Config::preprocessors` for convenience
to access the entire `output` and `preprocessor` tables.
- Moved the unit-tests that were setting environment variables to the
testsuite where it launches a process instead.

This fixes an issue where the `check` methods would inadvertently
rebuild the books if the `mdbook build` command is run. Normally this
isn't too much of an issue unless the `build` command is run with
options that affect the output.
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.
