* httpcaddyfile: Add shortcut for proxy hostport placeholder
I've noticed that it's a pretty common pattern to write a proxy like this, when needing to proxy over HTTPS:
```
reverse_proxy https://example.com {
header_up Host {http.reverse_proxy.upstream.hostport}
}
```
I find it pretty hard to remember the exact placeholder to use for this, and I continually need to refer to the docs when I need it. I think a simple fix for this is to add another Caddyfile placeholder for this one to shorten it:
```
reverse_proxy https://example.com {
header_up Host {proxy_hostport}
}
```
* Switch the shortcut name
* adding package command
* add-package command name
* refactoring duplicate code
* fixed by review
* fixed by review
* remove-package command
* commands in different files, common utils
* fix add, remove, upgrade packages in 1 file
* copyright and downloadPath moved
* refactor
* downloadPath do no export
* adding/removing multiple packages
* addPackages/removePackages, comments, command-desc
* add-package, process case len(args) == 0

* httpcaddyfile: ensure hosts to skip can always be collected
Previously, some hosts that should be skipped in logging would
be missed as the current logic would only collect them after
encountering the first server that would log. This change makes sure
the ServerLogConfig is initialized before iterating over the server
blocks.
* httpcaddyfile: add test case for skip hosts behavior
* feat: implement a simple timer to pull config

This commit fixes the `sortByNameDirFirst` variable inside fileserver to
match what browse's default template has.

If an email is specified in global options, a site called 'localhost' shouldn't be bunched together with public DNS names in the automation policies, which get the default, public-CA issuers. Fix old test that did this.
I also noticed that these two:
localhost {
}
example.com {
}
and
localhost, example.com {
}
produce slightly different TLS automation policies. The former is what the new test case covers, and we have logic that removes the empty automation policy for localhost so that auto-HTTPS can implicitly create one. (We prefer that whenever possible.) But the latter case produces two automation policies, with the second one being for localhost, with an explicit internal issuer. It's not wrong, just more explicit than it needs to be.
I'd really like to completely rewrite the code from scratch that generates automation policies, hopefully there is a simpler, more correct algorithm.
* Tweak compression settings
zstd: Limit window sizes to 128K to keep memory in control both server and client size.
zstd: Write 0 length frames. This may be needed for compatibility.
zstd: Create fewer encoders. Small memory improvement.
gzip: Allow -2 (Huffman only) and -3 (stateless) compression modes.
* Update modules/caddyhttp/encode/zstd/zstd.go
Update docs.

This is the more correct implementation of 23dadc0d86 (#4179)... I think. This commit effectively undoes the revert in 8848df9c5d, but with corrections to the logic.
We *do* need to use the original request path (the path the browser knows) for redirects, since they are external, and rewrites are only internal.
However, if the path was rewritten to a non-canonical path, we should not redirect to canonicalize that, since rewrites are intentional by the site owner. Canonicalizing the path involves modifying only the suffix (base element, or filename) of the path. Thus, if a rewrite involves only the prefix (like how handle_path strips a path prefix), then we can (hopefully!) safely redirect using the original URI since the filename was not rewritten.
So basically, if rewrites modify the filename, we should not canonicalize those requests. If rewrites only modify another part of the path (commonly a prefix), we should be OK to redirect.
Templates are parsed at request-time (like they are in the templates middleware) to allow live changes to the template while the server is running. Fixes race condition.
Also refactored use of a buffer so a buffer put back in the pool will not continue to be used (written to client) in the meantime.
A couple of benchmarks removed due to refactor, which is fine, since we know pooling helps here.
Also split the Caddyfile subdirective keepalive_idle_conns into two properties so the conns and conns_per_host can be set separately.
This is technically a breaking change, but probably anyone who this breaks already had a broken config anyway, and silently fixing it won't help them fix their configs.
While the Caddy project has had very few valid security bug reports over the years, we have a low signal-to-noise ratio with them (lots of invalid reports). Most are out of scope, and it can take too much valuable time for us to determine that. We would prefer researchers do this first. Hopefully these paragraphs spell out much more clearly what we do and don't accept.
* Force auto-renew for OCSP revoked status (maybe) (fix#4191)
* Use latest commit
* go.mod: Use CertMagic v0.14.0 (fix#4191)
Correctly replaces revoked certificates
In the Caddyfile, hosts specified for HTTP sockets (either scheme is "http" or it is on the HTTP port) should not be used as subjects in TLS automation policies (APs).
* logging: Implement dial timeout for net writer (fix#4083)
* Limit how often redials are attempted
This should cause dial blocking to occur only once every 10 seconds at most, but it also means the logger connection might be down for up to 10 seconds after it comes back online; oh well. We shouldn't block for DialTimeout at every single log emission.
* Clarify offline behavior
* caddyfile: Add parse error on site address in `{`
This is an incredibly common mistake made by users, so we should catch it earlier in the parser and give a more friendly message. Often it ends up adapting but with mistakes, or erroring out later due to other site addresses being read as directives.
There's not really ever a situation where a lone '{' is valid at the end of a site address (but I suppose there are edgecases where the user wants to use a path matcher where it ends specifically in `{`, but... why?), so this should be fine.
* Update caddyconfig/caddyfile/parse.go
Turns out this was an oversight, we assumed we could use `{http.response.header.*}` but that doesn't work because those are grabbed from the response writer, and we haven't copied any headers into the response writer yet.
So the fix is to set all the response headers into the replacer at a new namespace before running the handlers.
This adds the `{http.reverse_proxy.header.*}` replacer.

We decided that we'll use branches like `2.4` as the target for any changes that we might want to release in a `2.4.x` version like `2.4.1`, so that we can continue to merge changes targeting the next minor release (e.g. `2.5.0`) on master.
Our CI config wasn't set up for this to work properly though, since it was only running checks on PRs targeting master. This should fix it.
I couldn't find a way to do a pattern to only match digits for the branch names from Github's docs, it just looks like a pretty generic glob syntax. But this should do until we get to 3.0
