d43f1dbf6f docs: Move everything to docs.rs
A couple of things happened when preparing to release 3.0
- We needed derive documentation
  - I had liked how serde handled theres
  - I had bad experiences finding things in structopt's documentation
- The examples were broken and we needed tests
- The examples seemed to follow a pattern of having tutorial content and
  cookbook content
- We had been getting bug reports from people looking at master and
  thinking they were looking at what is currently released
- We had gotten feedback to keep down the number of places that
  documentation was located

From this, we went with a mix of docs.rs and github
- We kept the number of content locations at 2 rather than 3 by not
  having an external site like serde
- We rewrote the examples into explicit tutorials and cookbooks to align
  with the 4 styles of documentation
- We could test our examples by running `console` code blocks with
  trycmd
- Documentation was versioned and the README pointed to the last release

This had downsides
- The tutorials didn't have the code inlined
- Users still had a hard time finding and navigating between the
  different forms of documentation
- In practice, we were less likely to cross-link between the different
  types of documentation

Moving to docs.rs would offer a lot of benefits, even if it is only
designed for Rust-reference documentation and isn't good for Rust derive
reference documentation, tutorials, cookbooks, etc.  The big problem was
keeping the examples tested to keep maintenance costs down.  Maybe its
just me but its easy to overlook
- You can pull documentation from a file using `#[doc = "path"]`
- Repeated doc attributes get concatenated rather than first or last
  writer winning

Remember these when specifically thinking about Rust documentation made
me realize that we could get everything into docs.rs.

When doing this
- Tutorial code got brought in as was one of the aims
- We needed to split the lib documentation and the README to have all of
  the linking work.  This allowed us to specialize them according to
  their rule (user vs contributor)
- We needed to avoid users getting caught up in making a decision
  between Derive and Builder APIs so we put the focus on the derive API
  with links to the FAQ to help users decide when to use one or the
  other.
- Improved cross-referencing between different parts of the
  documentation
- Limited inline comments were added to example code
  - Introductory example code intentionally does not have teaching
    comments in it as its meant to give a flavor or sense of things and
    not meant to teach on its own.

This is a first attempt.  There will be a lot of room for further
improvement.  Current know downsides:
- Content source is more split up for the tutorials

This hopefully addresses #3189

db863de6c1 docs(examples): Show how to do default subcommands
While we don't have a built-in mechanism, its relatively easy to support
with the APIs we provide.

Inspired by #3566

272f840178 feat: Replace core set of AppSettings with functions
This is a part of #2717

Some settings didn't get getters because
- They are transient parse settings (e.g. ignore errors)
- They get propagated to args and should be checked there

`is_allow_hyphen_values_set` is a curious case.  In some cases, we only
check the app and not an arg.  This seems suspicious.

4b51b8e253 docs(examples): Steer people to know about about vs long_about
`#[clap(about)]` only overrides `about`.  If the doc comment also sets
`long_about`, it won't be overridden.  This change is to help raise
visibility of reseting `long_about` in these cases.

03cb509d6c refactor(examples): Change naming style
This is to make room for a reasonable looking cargo plugin example.

I got lazy and didn't update the tutorials.
