This PR adds a benchmark intended to measure how the LSP handles larger
repos, as well as its performance on a more realistic workload.
The repo being benchmarked is
[deco-cx/apps](https://github.com/deco-cx/apps) which has been vendored
along with its dependencies. It's included as a git submodule as its
fairly large. The LSP requests used in the benchmark are the actual
requests sent by VSCode as I opened, modified, and navigated around a
file (to simulate an actual user interaction).
The main motivation is to have a more realistic benchmark that measures
how we do with a large number of files and dependencies. The
improvements made from 1.42 to 1.42.3 mostly improved performance with
larger repos, so none of our existing benchmarks showed an improvement.
Here are the results for the changes made from 1.42 to 1.42.3 (the new
benchmark is the last one listed):
**1.42.0**
```test
Starting Deno benchmark
-> Start benchmarking lsp
- Simple Startup/Shutdown
(10 runs, mean: 379ms)
- Big Document/Several Edits
(5 runs, mean: 1142ms)
- Find/Replace
(10 runs, mean: 51ms)
- Code Lens
(10 runs, mean: 443ms)
- deco-cx/apps Multiple Edits + Navigation
(5 runs, mean: 25121ms)
<- End benchmarking lsp

This commit removes "Deno.core" namespace. It is strictly private API
that has no stability guarantees, we were supposed to remove it long time ago.

This commit splits `Deno.upgradeHttp` into two different APIs, because
the same API is currently overloaded with two different functions. Flash
requests upgrade immediately, with no need to return a `Response`
object. Instead you have to manually write the response to the socket.
Hyper requests only upgrade once a `Response` object has been sent.
These two behaviours are now split into `Deno.upgradeHttp` and
`Deno.upgradeHttpRaw`. The latter is flash only. The former only
supports hyper requests at the moment, but can be updated to support
flash in the future.
Additionally this removes `void | Promise<void>` as valid return types
for the handler function. If one wants to use `Deno.upgradeHttpRaw`,
they will have to type cast the handler signature - the signature is
meant for the 99.99%, and should not be complicated for the 0.01% that
use `Deno.upgradeHttpRaw()`.
This commit changes the `Deno.serve` function signature to be more
versatile and easier to use. It is now a drop in replacement for
std/http's `serve`.
The input validation has also been reworked.
- Merge "Deno.serve()" and "Deno.serveTls()" API
- Remove first argument and use "fetch" field options instead
- Update type declarations
- Add more documentation
