Only format Unexpected::Float with decimal point if it is finite
bef110b92a changed the display for unexpected floats to always append a
".0" if there was no decimal point found in the formatting of the float.

However, this should only be relevant for finite (i.e., not NaN or inf)
values.  The change introduced a test failure in the ordered-float
crate due to this:

     ---- impl_serde::test_fail_on_nan stdout ----
     thread 'impl_serde::test_fail_on_nan' panicked at 'assertion failed: `(left == right)`
       left: `Error { msg: "invalid value: floating point `NaN.0`, expected float (but not NaN)" }`,
      right: `"invalid value: floating point `NaN`, expected float (but not NaN)"`', src/lib.rs:1554:9

3d1b19ed90 Implement Ser+De for Saturating<T>
The serialization implementation is heavily
inspired by the existing trait implentation for
`std::num::Wrapping<T>`.

The deserializing implementation maps input values
that lie outside of the numerical range of the
output type to the `MIN` or `MAX` value of the
output type, depending on the sign of the input
value. This behaviour follows to the `Saturating`
semantics of the output type.

b8fafefd85 A few minor write_str optimizations and inlining
Apparently `write!` generates more code than `write_str` when used with a simple string, so optimizing it.

Mingun
84d1c5385d Use correct tokens in test to represent an enum variant
Unit variant of externally tagged enum cannot be deserialized from the string
token by itself. It is ContentDeserializer + serde_test::Deserializer that makes
this possible, because serde_test::Deserializer produces Content::Str() from
Token::BorrowedStr() and ContentDeserializer produces unit variant from Content::Str().

The following tokens all produces Content::String(variant):
- Token::String(variant)
- Token::Str(variant)
- Token::UnitVariant { variant, .. }

Token::BorrowedStr(variant) produces Content::Str(variant) that was the real purpose to
use it in test in #933. This actually makes this test testing `Content` rather than type itself.

Correct way to represent enum one of:
- [xxxVariant { .. }]
- [Enum { .. }, xxxVariant { variant, .. }]
- [Enum { .. }, String(variant), <variant content>]
- [Enum { .. }, Str(variant), <variant content>]
- [Enum { .. }, BorrowedStr(variant), <variant content>]

Point out serde(untagged) variants which are out of order
Previously if someone wrote an enum containing:

- `A` (untagged)
- `B` (tagged)
- `C` (tagged)
- `D` (untagged)
- `E` (tagged)
- `F` (untagged)

serde_derive would produce errors referring to B and E only, saying
you're supposed to put untagged variants at the end. The choice of B and
E for this error doesn't make a lot of sense because in order to resolve
the issue, the user must either:

- move A and D down

or:

- move B, C, and E up.

This commit changes the error to appear on A and D instead.
