INVITE did not exempt from +b unless the channel was coincidentally also +i.
This was a regression introduced in v2.4.0.

correctly account for nickname in CAP LS arithmetic

The arithmetic was assuming that the nickname is * (which it is
pre-registration). However, we were sending the actual nickname
post-registration. It would be simpler to always send *, but it
appears that the nickname is actually required by the spec:

>Replies from the server must [sic] contain the client identifier name or
>asterisk if one is not yet available.

+I should allow unregistered users to join a +R channel

See #1858: this was the intent all along, but I missed this issue.

fix the atheme side of #1864

Import stored certfps from Atheme as well.

There is no change in behavior since committing the transaction
already write(2)'s all the data to disk. But let's comply with
the official buntdb API.

This should have been done in 8b2f6de3e0, since we updated both
the database schema and the importer then.

send `*` for WHOX o (oplevel) instead of `0`

Jobe points out that 0 is a valid oplevel in some contexts,
* is a better placeholder for "unimplemented".

anope2json, atheme2json: handle non-UTF8 data

fix #1860

disallow initial $ in nicknames

fix #1858

CS AMODE changes should take immediate effect even if the nick
does not match the account.

The channel mode +R used to both prevent joins by unregistered users,
and prevent unregistered users who happened to be joined from speaking.
This changes the behavior so that +R only prevents joins:

1. This allows users who were invited or SAJOIN'ed to speak
2. To restore the old semantics, chanops can set +RM

It collides with the massmessage mask syntax. Reported by @emersion

make +C (no CTCP) a default channel mode

* Build container image on aarch64 platform

* Revert test code & correct typo
