Follow the instructions from https://github.com/salsa-rs/salsa/issues/340#issuecomment-1210153085.
Still not sure what to do with `fmt_index`...

360: Permit renaming constructors, getters and setters r=nikomatsakis a=MihailMihov
The goal is to add an option `constructor_name` to `#[salsa::input]`, `#[salsa::interned]` and `#[salsa::tracked]` that allows changing the name of the generated constructor. After that add attributes `get` and `set` to the fields which allow overriding the names of the getters and setters. In the end the following snippet should compile and work:
```rust
#[salsa::interned(constructor = from_string)]
struct MyInterned {
#[get(text)] #[set(set_text)] #[return_ref]
field: String,
}
impl MyInterned {
pub fn new(db: &dyn Db, s: impl Display) -> MyInterned {
MyInterned::from_string(db, s.to_string())
}
pub fn field(self, db: &dyn Db) -> &str {
self.text(db)
}
pub fn set_field(self, db: &mut dyn Db, id: String) {
self.set_text(&mut db, id)
}
}
```

352: Add options to tracked funcitons for lru capacity r=nikomatsakis a=XFFXFF
fixes#344
Now we can write something like the following to set the lru capacity of tracked functions
```rust
#[salsa::tracked(lru=32)]
fn my_tracked_fn(db: &dyn crate::Db, ...) { }
```
some details:
* lru should not be combined with specify. We will report an error if people do #[salsa::tracked(lru = 32, specify)]
* set 0 as default capacity to disable LRU (Because I think doing this would make the code simpler when implementing `create_ingredients` of tracked functions).
* old salsa support to change lru capacity at runtime, [as noted here](https://salsa-rs.github.io/salsa/rfcs/RFC0004-LRU.html?highlight=change#reference-guide), but we do not support this now

Accumulators don't currently work across revisions
due to a few bugs. This commit adds 2 tests to show
the problems and reworks the implementation strategy.
We keep track of when the values in an accumulator were pushed
and reset the vector to empty when the push occurs in a new
revision.
We also ignore stale values from old revisions
(but update the revision when it is marked as validated).
Finally, we treat an accumulator as an untracked read,
which is quite conservative but correct. To get better
reuse, we would need to (a) somehow determine when different
values were pushed, e.g. by hashing or tracked the old values;
and (b) have some `DatabaseKeyIndex` we can use to identify
"the values pushed by this query".
Both of these would add overhead to accumulators and I didn'τ
feel like doing it, particularly since the main use case for
them is communicating errors and things which are not typically
used from within queries.
We don't do anything with this info right now besides log it,
but the logs show we are reporting it at the right times
in the `specify_tracked_fn_in_rev_1_but_not_2` test
(also fix an oversight in the test where it was creating a new input
each time).

336: Add options to tracked functions for cycle recovery r=nikomatsakis a=XFFXFF
closes#331
This pr ports the old salsa tests for cycle in a single thread, except for [cycle_disappears_durability](03a27a7054/tests/cycles.rs (L326)), since we don't have the api that permits setting durability.
~I haven't ported parallel related tests, which would be some work, wondering if we can merge this in first~
