Jetty vulnerable to Invalid HTTP/2 requests that can lead to denial of service
### Description
Invalid HTTP/2 requests (for example, invalid URIs) are incorrectly handled by writing a blocking error response directly from the selector thread.
If the client manages to exhaust the HTTP/2 flow control window, or TCP congest the connection, the selector thread will be blocked trying to write the error response.
If this is repeated for all the selector threads, the server becomes unresponsive, causing the denial of service.
### Impact
A malicious client may render the server unresponsive.
### Patches
The fix is available in Jetty versions 9.4.47. 10.0.10, 11.0.10.
### Workarounds
No workaround available within Jetty itself.
One possible workaround is to filter the requests before sending them to Jetty (for example in a proxy)

Jetty invalid URI parsing may produce invalid HttpURI.authority
### Description
URI use within Jetty's `HttpURI` class can parse invalid URIs such as `http://localhost;/path` as having an authority with a host of `localhost;`.
A URIs of the type `http://localhost;/path` should be interpreted to be either invalid or as `localhost;` to be the userinfo and no host.
However, `HttpURI.host` returns `localhost;` which is definitely wrong.
### Impact
This can lead to errors with Jetty's `HttpClient`, and Jetty's `ProxyServlet` / `AsyncProxyServlet` / `AsyncMiddleManServlet` wrongly interpreting an authority with no host as one with a host.
### Patches
Patched in PR [#8146](https://github.com/eclipse/jetty.project/pull/8146) for Jetty version 9.4.47.
Patched in PR [#8014](https://github.com/eclipse/jetty.project/pull/8015) for Jetty versions 10.0.10, and 11.0.10
### Workarounds
None.
