Example:
```
test
testitem
```
Select line 2 with x, then type Alt-C; Helix will go into an infinite
loop. The saturating_sub keeps the head_row and anchor_row pinned at 0,
and a selection is never made since the first line is too short.

`:write` and other file-saving commands now check the file modification

The loop always iterates the number of times the user specified even
if the beginning/end of the document is reached.
For an extreme demonstration try the following commands, Helix will
hang for several seconds.
100000000w
100000000]c
This matches the behavior from 42ad1a9e04
but for the first and last change. The selection rules are the same
as for goto_next/prev_change: additions and modifications select the
added and modified range while deletions are represented with a point.
This will allow testing more of the code base, as well as enable UI-
specific testing.
Debug mode builds are prohibitively slow for the tests, mostly
because of the concurrency write tests. So there is now a profile for
integration tests that sets the optimization level to 2 for a few helix
crates, and lowers the number of rounds of concurrent writes to 1000.

If the last argument to shellwords ends in a multibyte utf8 character
the entire argument will be dropped.
e.g. `:sh echo test1 test2𒀀` will only output `test1`
Add additional tests based on the code review feedback
This change makes `ms<ret>` work similarly to `t<ret>` and related
find commands: when the next event is a keypress of Enter, surround
the selection with the document's line-endings.
The purpose of this change is to remove the mutable self borrow on
`HighlightIterLayer::sort_key` so that we can sort layers with the
correct ordering using the `Vec::sort` function family.
`HighlightIterLayer::sort_key` needs `&mut self` since it calls
`Peekable::peek` which needs `&mut self`. `Vec::sort` functions
only give immutable borrows of the elements to ensure the
correctness of the sort.
We could instead approach this by creating an eager Peekable and using
that instead of `std::iter::Peekable` to wrap `QueryCaptures`:
```rust
struct EagerPeekable<I: Iterator> {
iter: I,
peeked: Option<I::Item>,
}
impl<I: Iterator> EagerPeekable<I> {
fn new(mut iter: I) -> Self {
let peeked = iter.next();
Self { iter, peeked }
}
fn peek(&self) -> Option<&I::Item> {
self.peeked.as_ref()
}
}
impl<I: Iterator> Iterator for EagerPeekable<I> {
type Item = I::Item;
fn next(&mut self) -> Option<Self::Item> {
std::mem::replace(&mut self.peeked, self.iter.next())
}
}
```
This would be a cleaner approach (notice how `EagerPeekable::peek`
takes `&self` rather than `&mut self`), however this doesn't work in
practice because the Items emitted by the `tree_sitter::QueryCaptures`
Iterator must be consumed before the next Item is returned.
`Iterator::next` on `tree_sitter::QueryCaptures` modifies the
`QueryMatch` returned by the last call of `next`. This behavior is
not currently reflected in the lifetimes/structure of `QueryCaptures`.
This fixes an issue with layers being out of order when using combined
injections since the old code only checked the first range in the
layer. Layers being out of order could cause missing highlights for
combined-injections content.

* rework positioning/rendering, enables softwrap/virtual text
This commit is a large rework of the core text positioning and
rendering code in helix to remove the assumption that on-screen
columns/lines correspond to text columns/lines.
A generic `DocFormatter` is introduced that positions graphemes on
and is used both for rendering and for movements/scrolling.
Both virtual text support (inline, grapheme overlay and multi-line)
and a capable softwrap implementation is included.
