* spec update: metadata keys are lowercase
* add batch parameter to metadata batches
* fix: connecting clients receive METADATA, not RPL_KEYVALUE
* spec update: send RPL_METADATASUBS in a metadata-subs batch
* move some helpers
* bump irctest to forked hash
This is https://github.com/progval/irctest/pull/314 but I don't want to
couple the merges
* fix: empty value is valid
* fix: deleting a nonexistent key gets a FAIL
* metadata spec update: disallow colon entirely
* refactor key validation
* implement metadata before-connect
* play the metadata in reg burst to all clients with the cap
* bump irctest
* remove all case normalization for keys
From spec discussion, we will most likely either require keys to be lowercase,
or else treat them as case-opaque, similar to message tag keys.
* refactoring
* send an empty batch if necessary, as per spec
* don't broadcast no-op updates
* don't trim spaces before validating the key
* bump irctest to cover metadata
* replay existing metadata to reattaching always-on clients
* use canonicalized name everywhere
* use utils.SafeErrorParam in FAIL lines
* validate key names for sub
* fix error for METADATA CLEAR
* max-keys is enforced for channels as well
* remove unlimited configurations
* maintain the limit exactly without off-by-one cases
* add final channel registration check
* nickserv.go: Update FAIL codes to match spec
* handlers.go: Fix FAIL code
* use ACCOUNT_EXISTS for errNameReserved
* bump irctest to development version

Block uses of the JS Fetch API to send HTTP message bodies that are also valid
IRC. The constraint on such messages is that they must begin with a valid HTTP
verb; we can detect this and reject them immediately.
time.Unix() returns a time.Time with the Location populated to the server's
timezone. Such times will format incorrectly with IRCv3TimestampFormat unless
they are manually converted to UTC.
Hide the message-redaction capability if allow-individual-delete is disabled.
(Technically REDACT can still be used, but only by ircops, so advertising it
is misleading in the most common case).
getPushSubscriptions() could have a stale view of the latest subscription
renewal and successful push times. We don't want to rebuild on every renewal
or every push, so add a boolean refresh argument that controls rebuilding.
