* implement default values for header directive
closes#3804
* remove `set_default` header op and rely on "require" handler instead
This has the following advantages over the previous attempt:
- It does not introduce a new operation for headers, but rather nicely
extends over an existing feature in the header handler.
- It removes the need to specify the header as "deferred" because it is
already implicitely deferred by the use of the require handler. This
should be less confusing to the user.
* add integration test for header directive in caddyfile
* bubble up errors when parsing caddyfile header directive
* don't export unnecessarily and don't canonicalize headers unnecessarily
* fix response headers not passed in blocks
* caddyfile: fix clash when using default header in block
Each header is now set in a separate handler so that it doesn't clash
with other headers set/added/deleted in the same block.

Before, if there was an error in the error handler, we would not write a
status code, which resulted in Go writing a 200 for us by default, which
does not make sense when there's an error. Now we write the second
error's status if available, otherwise 500.
* caddytls: Support multiple issuers
Defaults are Let's Encrypt and ZeroSSL.
There are probably bugs.
* Commit updated integration tests, d'oh
* Update go.mod
* nitpicks and small improvements in basicauth module
1:
roll two if statements into one, since err will be nil in the second case anyhow
2:
unlock cache mutex after reading the key, as this happens by-value and reduces code complexity
3:
switch cache sync.Mutex to sync.RWMutex for better concurrency on cache fast track
* allocate the right kind of mutex
* fileserver: Improve and clarify file hiding logic
* Oops, forgot to run integration tests
* Make this one integration test OS-agnostic
* See if this appeases the Windows gods
* D'oh
Always follow the code path of hashing and comparing a plaintext
password even if the account is not found by the given username; this
ensures that similar CPU cycles are spent for both valid and invalid
usernames.
Thanks to @tylerlm for helping and looking into this!
We have users that have site blocks like *.*.tld with on-demand TLS
enabled. While *.*.tld does not qualify for a publicly-trusted cert due
to its wildcards, On-Demand TLS does not actually obtain a cert with
those wildcards, since it uses the actual hostname on the handshake.
This improves on that logic, but I am still not 100% satisfied with the
result since I think we need to also check if another site block is more
specific, like foo.example.tld, which might not have on-demand TLS
enabled, and make sure an automation policy gets created before the
more general policy with on-demand...

wip
* logging: Implement Caddyfile support for ip_mask
* logging: Get rid of unnecessary logic to allow strings, not that useful
* logging: Add adapt test
Now, a filename to hide that is specified without a path separator will
count as hidden if it appears in any component of the file path (not
only the last component); semantically, this means hiding a file by only
its name (without any part of a path) will hide both files and folders,
e.g. hiding ".git" will hide "/.git" and also "/.git/foo".
We also do prefix matching so that hiding "/.git" will hide "/.git"
and "/.git/foo" but not "/.gitignore".
The remaining logic is a globular match like before.
Update internal issuer for compatibility -- yay simpler code!
The .1 version also fixes non-critical SAN extensions that caused trust
issues on several clients.

* caddytls: Add support for ZeroSSL; add Caddyfile support for issuers
Configuring issuers explicitly in a Caddyfile is not easily compatible
with existing ACME-specific parameters such as email or acme_ca which
infer the kind of issuer it creates (this is complicated now because
the ZeroSSL issuer wraps the ACME issuer)... oh well, we can revisit
that later if we need to.
New Caddyfile global option:
{
cert_issuer <name> ...
}
Or, alternatively, as a tls subdirective:
tls {
issuer <name> ...
}
For example, to use ZeroSSL with an API key:
{
cert_issuser zerossl API_KEY
}
For now, that still uses ZeroSSL's ACME endpoint; it fetches EAB
credentials for you. You can also provide the EAB credentials directly
just like any other ACME endpoint:
{
cert_issuer acme {
eab KEY_ID MAC_KEY
}
}
All these examples use the new global option (or tls subdirective). You
can still use traditional/existing options with ZeroSSL, since it's
just another ACME endpoint:
{
acme_ca https://acme.zerossl.com/v2/DV90
acme_eab KEY_ID MAC_KEY
}
That's all there is to it. You just can't mix-and-match acme_* options
with cert_issuer, because it becomes confusing/ambiguous/complicated to
merge the settings.

* Add support for ZeroSSL's EAB-by-email endpoint
Also transform the ACMEIssuer into ZeroSSLIssuer implicitly if set to
the ZeroSSL endpoint without EAB (the ZeroSSLIssuer is needed to
generate EAB if not already provided); this is now possible with either
an API key or an email address.
* go.mod: Use latest certmagic, acmez, and x/net

We can't use a positional index on an original string that we got from
its lower-cased equivalent. Implement our own IndexFold() function b/c
the std lib does not have one.

We already restore them within the retry loop, but after successful

see the values used for proxying.

example.com if there is no key example.com:1234.
