Jan Špaček ae6cfd3baf Improve optional support for borsh serialization 
- Do not allocate when deserializing ArrayString
- Serialize length as u32, not as u64, to be consistent with
  serialization of [T] and str
- Add tests

bluss b7f3aa9fce FIX: Add new_const() for const construction and revert new to old version 
The new() function is significantly faster, it optimizes better at the
moment/in current rust. For this reason, provide a const fn constructor,
but not as the default `new`.

bluss 0c90469b61 FEAT: Use u32 for the length field in arrayvec 
Store the length as u32 internally. This is to shrink the size of the
ArrayVec value (when possible, depending on element type).

Inline storage vectors larger than u32::MAX are very unlikely to be
useful - for these cases, prefer using Vec instead.

It's not possible to have the CAP type parameter be of type u32 (missing
features in const evaluation/const generics). We also have to panic at
runtime instead of having a static assertion for capacity, for similar
reasons.

bluss a554ea219a API: Panic in .extend() and from_iter on capacity exceeded 
This regresses performance of the .extend(s) benchmark where s is a
slice; to compensate add a private extend_from_slice method that we can
use where possible (clone_from, try_from).

bluss 18877f243a TEST: Fix size assertion test for const gen 
With const generics we can't avoid the usize (or other type) length
field.

bluss 5502324b6f TEST: Fix arrayvec tests for const gen 
Just search/replace for syntax [T; N] -> T, N and it works.

bluss 8093e8d886 FEAT: Switch to using MaybeUninit for everything 
Use std::mem::MaybeUninit and stop using nodrop as a fallback.
This means we require Rust 1.36

bluss 93220e55ae TEST: Update tests for new MaybeUninit usage 
(Also remove the size check since we can't rely on it, even if we want
to ensure it has no overhead for the bytes case.)

Aleksei Voronov 9207e7442f Implement FromStr for ArrayString 
This is very useful for generic code that may want to parse arbitrary
input string into arbitrary other types.

Limitations of the FromStr trait don't allow us to keep the original string slice
inside the CapacityError, unfortunately.

  TEST: Add test that ensures the MaybeUninit impl is used on nightly
  FIX: Remove use of uninitialized in ArrayString

bluss 8f8617b967 TEST: Add test that Some(ArrayVec<[&_;_]>).is_some() 
This seems like a trivial test, but since it can fail, it shows us that
we don't have a sound implementation yet.

remaining capacity.

bluss ac61ce748b TEST: Fix drop tests for older Rust 
In the test, test with Vec first to see how Rust implements panic
recovery while elements drop. If Vec drops all the elements, then we
test that arrayvec does too.

try_insert has a capacity error, but panics if the index is out of
