update metadata corresponding to spec edits (#2282)
Some checks failed
build / build (push) Has been cancelled
Details
ghcr / Build (push) Has been cancelled
Details 
* 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

implement metadata before-connect (#2281) 
* 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.

safer 005 length limits (#2241) 
* Limit the payload to 380 bytes instead of 400
* Don't translate the final parameter

This leaves about 60 bytes for the server name.

block HTTP DoS attacks (#2239)
Some checks failed
build / build (push) Has been cancelled
Details
ghcr / Build (push) Has been cancelled
Details 
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.

7b71839615 fix buggy persistence of push timestamps 
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.

See #1686; this allows i2pd to pass the i2p address to Ergo, which may be
useful for moderation under some circumstances.

cab192e2af fix #2130 
We load registered channels unconditionally; reloading them again on rehash
is incorrect. This caused buggy behavior when channel registration was
disabled in the config, but some registered channels were already loaded.

35128bfc23 use new aligned atomic types everywhere 
See 69448b13a1 / #1969; the compiler can now ensure that a uint64
intended for atomic access is always aligned to a 64-bit boundary.
Convert atomic operations on uint32s and pointers as well.
