Add unqualified JSDoc member references (#44202)
* Add unqualified JSDoc member references

This allows unqualified references like:

```ts
class Zero {
 /** @param buddy Must be {@link D_HORSE} or {@link D_DOG}. */
 deploy(buddy: number) { }
 static D_HORSE = 1
 static D_DOG = 2
}
```

I surveyed @see and @link again to estimate how common this is. I found
a little over 200 uses, which is around 2%. Sorted by frequency, this
*is* the next feature on the list, along with the `module:` prefix.
So I think this is about the right point to stop adding code.

In this case, however, I liked most of the uses -- there were a lot
of deprecated functions that referenced a function just below, where it
would be wordy to qualify the name, but the reader would benefit from a
link.

Note that unqualified references do *not* work inside type or object
literals. The code I ended up with is quite complicated and I didn't
observe any uses in the wild.

Fixes #43595

* Remove type/object literal container check

Since they don't work anyway

Kick out of normalizePath if there's nothing to do (#44173)
* Kick out of normalizePath if there's nothing to do

...using `relativePathSegmentRegExp`.

Bonus: use a regex to handle "/./" to avoid splitting and joining in a
common case.

When building the compiler, for example, it looks like ~95% of arguments
to `normalizePath` do not require any normalization.

* Check normalization before and after . cleanup

* Also cleanup leading ./

Avoid calling replace in normalizeSlashes when it would do nothing (#44100)
* Make normalizeSlashes a no-op there are no bad slashes

On Windows, there will probably be a negligible slowdown, iterating over
the pre-slash prefix of each unnormalized path (though we might come out
ahead if paths are normalized more than once).

On *nix, this saves work - 1.8s -> 0.4s in the project I'm
investigating.

* Reuse already-computed index

Add jsdoc member names: Class#method (#44150)
* Everything mostly works

A couple of mixed, nested references don't work yet.
The scanner+parser interaction is wrong, the parser consumes one too
many spaces, and the checker+services code needs a little cleanup.

* Cleanup

1. I decided that correctly parsing a#b.c, an entity name containing an
instance reference, is not worth the work.
2. I made the scanner, at least the jsdoc part, emit a # token, and
provided a reScanPrivateIdentifier in order to convert #a to # a.
3. I cleaned up the code in the checker.
2. Unrelated: I added a missing space in linkPart display.

* Cleanup lint + var naming

* investigate+clean up a couple of TODOs

* Fix lint in utilities.ts

* change name to JSDocMemberName

* address PR comments

Improve parser recovery for unclosed/mismatched JSX elements (#43780)
* First draft

Everything works, the error messages for unmatched opening elements
could still use improvement, plus there is tonnes of unused and ugly
code.

1. Make sure the parser can recover from all kinds of unclosed tags.
2. Improve the parse tree for unmatched opening tags.
3. Better errors at some point.

* Lots of cleanup

* Improve readability of construction/fix lint

* improve line-length formatting

5ca7983ebe Fix the code that checks for variadic signatures
This code looks strange, like there's a typo in it (eg, using `lists` in
the `parameterList` loop, etc) -- so I also refactored it a bit to look
more intentional.  The new format makes it clearer that `lists` is
checked once *outside* the loop, as well as the role of
`hasEffectiveRestParameter`.

The actual bug fix is checking `pList.length` in the new `isVariadic()`.

Fixes 41059.
