Prevents re-checking strings we already know are latin-1. Small
improvement: 115k->116k

This switches syscall used in HTTP and WS server from "writev"
to "sendto".
"DENO_USE_WRITEV=1" can be used to enable using "writev" syscall.
Doing this for easier testing of various setups.

This PR attempts to resolve the first item on the list from
https://github.com/denoland/deno/issues/19330 which is about using a
flat list of interleaved key/value pairs, instead of a nested array of
tuples.
I can tackle some more if you can provide a quick example of using raw
v8 arrays, cc @mmastrac

Under heavy load, we often have requests queued up that don't need an
async call to retrieve. We can use a fast path sync op to drain this set
of ready requests, and then fall back to the async op once we run out of
work.
This is a .5-1% bump in req/s on an M2 mac. About 90% of the handlers go
through this sync phase (based on a simple instrumentation that is not
included in this PR) and skip the async machinery entirely.

Add Brotli streaming compression to HTTP
|
|
Necessary for #3326.
Requested in #10214 as well.
|
|
Fixes for various `Attemped to access invalid request` bugs (#19058,
#15427, #17213).
We did not wait for both a drop event and a completion event before
removing items from the slab table. This ensures that we do so.
In addition, the slab methods are refactored out into `slab.rs` for
maintainability.

Merges `op_http_upgrade_next` and `op_ws_server_create`, significantly
simplifying websocket construction in ext/http (next), and removing one
JS -> Rust call. Also WS server now doesn't bypass
`HttpPropertyExtractor`.

Improve abstractions around listeners to support listener + connection
network stream combinations not previously possible (for example a
listener exposed as a Tcp, creating Unix network streams).

(#19056)
Partially supersedes #19016.
This migrates `spawn` and `spawn_blocking` to `deno_core`, and removes
the requirement for `spawn` tasks to be `Send` given our single-threaded
executor.
While we don't need to technically do anything w/`spawn_blocking`, this
allows us to have a single `JoinHandle` type that works for both cases,
and allows us to more easily experiment with alternative
`spawn_blocking` implementations that do not require tokio (ie: rayon).

`Content-Encoding: gzip` support for `Deno.serve`. This doesn't support
Brotli (`br`) yet, however it should not be difficult to add. Heuristics
for compression are modelled after those in `Deno.serveHttp`.
Tests are provided to ensure that the gzip compression is correct. We
chunk a number of different streams (zeros, hard-to-compress data,
already-gzipped data) in a number of different ways (regular, random,
large/small, small/large).

Fixes #16699 and #18960 by ensuring that we release our HTTP
`spawn_local` tasks when the HTTP resource is dropped.
Because our cancel handle was being projected from the resource via
`RcMap`, the resource was never `Drop`ped. By splitting the handle out
into its own `Rc`, we can avoid keeping the resource alive and let it
drop to cancel everything.

Fix internal "upgradeHttpRaw" API restoring capability to upgrade HTTP
connection in polyfilles "node:http" API.

This implements HTTP/2 prior-knowledge connections, allowing clients to
request HTTP/2 over plaintext or TLS-without-ALPN connections. If a
client requests a specific protocol via ALPN (`h2` or `http/1.1`),
however, the protocol is forced and must be used.

requests cannot cause a panic (#18810)
Fix a bug where we weren't saving `slabId` in #18619, plus add some
robustness checks around multiple upgrades (w/test).
|

This is a rewrite of the `Deno.serve` API to live on top of hyper
1.0-rc3. The code should be more maintainable long-term, and avoids some
of the slower mpsc patterns that made the older code less efficient than
it could have been.
Missing features:
- `upgradeHttp` and `upgradeHttpRaw` (`upgradeWebSocket` is available,
however).
- Automatic compression is unavailable on responses.
