* caddyhttp: Reject 0-RTT early data in IP matchers and set Early-Data header when proxying
See RFC 8470: https://httpwg.org/specs/rfc8470.html
Thanks to Michael Wedl (@MWedl) at the University of Applied Sciences St. Poelten for reporting this.
* Don't return value for {remote} placeholder in early data
* Add Caddyfile support
SanitizePathJoin protects against directory traversal attacks by
checking for requests whose URL path look like they are trying to
request something other than a local file, and returns the root
directory in those cases.
The method is also careful to ensure that requests which contain a
trailing slash include a trailing slash in the returned value. However,
for requests that contain only a slash (requests for the root path), the
IsLocal check returns early before the matching trailing slash is
re-added.
This change updates SanitizePathJoin to only perform the
filepath.IsLocal check if the cleaned request URL path is non-empty.
---
This change also updates the existing SanitizePathJoin tests to use
filepath.FromSlash rather than filepath.Join. This makes the expected
value a little easier to read, but also has the advantage of not being
processed by filepath.Clean like filepath.Join is. This means that the
exact expect value will be compared, not the result of first cleaning
it.
Fixes#6352

Before this change, a read of size (let's say) < 10, into a buffer of size 10, will return EOF because we're using CopyN to limit to the size of the buffer. That resulted in the body being read from later, which should only happen if it couldn't fit in the buffer.
With this change, the body is properly NOT set when it can all fit in the buffer.

* Added plaintext support to file_server browser
This commit is twofold: First it adds a new optional
field, `return_type`, to `browser` for setting the
default format of the returned index (html, json or plaintext).
This is used when the `Accept` header is set to `/*`.
Second, it adds a preliminary `text/plain`
support to the `file_server` browser that
returns a text representation of the file
system, when an `Accept: text/plain` header
is present, with the behavior discussed above.
* Added more details and better formatting to plaintext browser
* Replaced returnType conditions with a switch statement
* Simplify

* caddyhttp: add `http.request.local{,.host,.port}` placeholder
This is the counterpart of `http.request.remote{,.host,.port}`.
`http.request.remote` operates on the remote client's address, while
`http.request.local` operates on the address the connection arrived on.
Take the following example:
- Caddy serving on `203.0.113.1:80`
- Client on `203.0.113.2`
`http.request.remote.host` would return `203.0.113.2` (client IP)
`http.request.local.host` would return `203.0.113.1` (server IP)
`http.request.local.port` would return `80` (server port)
I find this helpful for debugging setups with multiple servers and/or
multiple network paths (multiple IPs, AnyIP, Anycast).

* caddyhttp: add unit test for `http.request.local{,.host,.port}`
* caddyhttp: add integration test for `http.request.local.port`
* caddyhttp: fix `http.request.local.host` placeholder handling with unix sockets
The implementation matches the one of `http.request.remote.host` now and
returns the unix socket path (just like `http.request.local` already did)
instead of an empty string.

previously the `caddy respond` command would treat the argument
passed to --listen as a TCP socket address, iterating over a possible
port range.
this patch factors the server creation out into a separate function,
allowing this to be reused in case the listen address is a unix network
address.

* templates: Offically make templates extensible
This supercedes #4757 (and #4568) by making template extensions
configurable.
The previous implementation was never documented AFAIK and had only
1 consumer, which I'll notify as a courtesy.
* templates: Add 'maybe' function for optional components
* Try to fix lint error
* core: quic listener will manage the underlying socket by itself.
* format code
* rename sharedQUICTLSConfig to sharedQUICState, and it will now manage the number of active requests
* add comment
* strict unwrap type
* fix unwrap
* remove comment
* Browse.html: Add canonical URL and home-link
When contents are equal, but maybe just a sort order is different, it is good to add `<link rel="canonical" href="base-path/" />`. This helps search engines propeely index the page.
I also added a link to the home page with the name of `{{.Host}}` just above the bread crumbs to make the page clearer.

This makes debug logging very noisy when reverse proxying, but I guess
that's the point.
This has shown to be useful in troubleshooting infrastructure issues.

* Enhancement: Allow X-Forwarded-For Header in httpInclude Virtual Requests
The goal of this enhancement is to modify the funcHTTPInclude function in the Caddy codebase to include the X-Forwarded-For header in the virtual request. This change will enable reverse proxies to set the X-Forwarded-For header, ensuring that the client's IP address is correctly provided to the target endpoint. This modification is essential for applications that depend on the X-Forwarded-For header for various functionalities, such as authentication, logging, or content customization.
