4b926e1908 Change`MAX and `MIN` to equal `MAX_MONEY` (Jamil Lambert, PhD)
Pull request description:
To prevent rounding errors converting to and from f64 change `SignedAmount` `MAX` and `MIN` to +/- `MAX_MONEY` which are within the limit in f64 that has issues.
Add checks to `from_str_in`, `checked_add`, `checked_sub` and `checked_mul` that the result is within MIN and MAX.
Modify tests to work with new `MIN` and `MAX`.
Discussed in #3688 and #3691

There are two `private` modules in `amount` but they do slightly
different things. One provides a private `Token` and one is for trait
sealing. We have various other trait sealing modules in the codebase and
they are all called `sealed` not `private`. Also the seal trait is
called `Sealed`.
Rename the `private` module and the trait to be uniform with the rest of
the codebase.

Use the `must_use_candidate` clippy lint to find all functions that are
candidates for having `must_use`.
Add `must_use` attribute but exclude obvious functions like `from_`,
`to_`, and `new`.
This patch is subjective.

To prevent rounding errors converting to and from f64 change
`Amount::MAX` to `MAX_MONEY` which is below the limit in f64 that has
issues.
Add checks to `from_str_in`, `checked_add` and `checked_mul` that the
result is below MAX, where previously a u64 overflow was relied on.
Change tests to account for new lower MAX that is within the range of
SignedAmount and does not overflow so easily
Remove overflow tests
`Amount::MAX` is now below `u64::MAX` and within the range of values for
`SignedAmount`. These tests therefore do not overflow.
In effective_value there is no error with `Amount::MAX` and the correct
value is returned.
In psbt the removed test is effectively the same as the previous test.
Modify `Amount` tests to work with new `MAX`
Tests need to be changed that checked values above the new `MAX` or
`Amount::MAX` was out of range for `SignedAmount` which it isn't anymore
Sometimes JSON parsers may munge floats. Instead of using `f64` we can
serialize BTC amounts as strings.
Includes addition of `alloc` feature gate to `DisplayFullError` to
remove lint warnings when building with `--no-default-features`.

The `Amount` and `SignedAmount` were not supposed to implement `serde`
traits by design because doing so implicitly uses sats. We provide two
modules `as_sat` and `as_btc` to allow users to explicitly serialize in
their preferred format.
In commit: `d57ec019d5 Use Amount type for TxOut value field` derives
were added for `serde` and we did not notice it during review.

Add a comment to the `serde` module about why we have all the `alloc`
feature gating.
Done as part of #3556 - auditing the whole crate for use of `alloc`
feature.
Mark `checked_` functions const. Replace `map()` and `?` operators,
which are not allowed in const context, with match statements.
Use descriptive variable names in ceiling division to make
it easier to follow.
There is a range of different wordings used in the docs of constructor
type functions.
Change all to start with `Constructs a new` or `Constructs an empty`.
In functions that act like constructors there is a mixture of the usage
of `creates` and `constructs`.
Replace all occurrences of `creates` with `constructs` in the first line
of docs of constructor like functions.
The docs on `FromStr` say "string slice is zero" but actually mean to
document the behaviour when the value represented is zero.
Also the fact that `FromStr` returns an error if parsing fails is self
evident.
Fix the rustdocs on `Amount` and `SignedAmount` by doing:
- Make them uniform
- Use correct style (looks like `SignedAmount` got left behind when we
improved `Amount`)
Add/update the from_int group of functions to provide one that errors
and one that is const and panics (errors in const context are not useful
because one cannot call `unwrap` in const context).
In an effort to make the `amount` module more readable move the
`SignedAmount` type to a private submodule.
Re-export everything so this is not a breaking change.
Code move and re-exports only.
When we move `SignedAmount` to a submodule linking to `self` introduces
a clippy warning, I'm not exactly sure why but lets remove the link in
preparation for the move.
In an effort to make the `amount` module more readable move the `Amount`
type to a private submodule.
Re-export everything so this is not a breaking change.
Code move and re-exports only.
There is _a lot_ of error types in the `amount` module. Move them to a
separate `error` module.
Add a bunch of `pub(super)` to keep things private to the `amount`
module.
Eventually we will want to close all these errors.
In preparation for splitting the error types out of `amount.rs` into
their own file move the `amount.rs` file to `amount/mod.rs`.
File move only, no other changes.
