util.prosodyctl.check: Check cert for HTTPS if http module enabled

util.prosodyctl.check: Update conditions for s2s cert checks The 'anonymous_login' setting is deprecated and prosodyctl check config will tell you to change it to 'authentication = "internal_hashed"', so we shouldn't need to care about here anymore.

util.prosodyctl.check: Simplify conditions for c2s and s2s cert checks This code is hard to follow and in need of some refactoring.

tools/build-env: Tools for building and testing in a container ./tools/build-env/build.sh Creates a container image based on Debian or Ubuntu ./tools/build-env/here.sh Starts a container and mounts in the current working directory, from where one can ./configure; make; make test etc

mod_s2s_auth_dane_in: Bail out on explicit service denial

mod_tokenauth: Include more details in debug logs Had a hard time following what was happening when it did not specify which grant or token was being removed.

net.http: Set Connection header based on connection pool usage Connection: keep-alive is implicit in HTTP/1.1 but explicit > implicit

net.http: Add simple connection pooling This should speed up repeated requests to the same site by keeping their connections around and sending more requests on them. Sending multiple requests at the same time is not supported, instead a request started while another to the same authority is in progress would open a new one and the first one to complete would go back in the pool. This could be investigated in the future. Some http servers limit the number of requests per connection and this is not tested and could cause one request to fail, but hopefully it will close the connection and prevent it from being reused.

mod_storage_sql: Use UUIDv7 as keys Potentially allows sorting on those directly as they will be in increasing order.

util.uuid: Add UUIDv7 Allows sorting by id as a substitute for sorting by timestamp since it has the timestamp in the encoded in the first part, and only things that happen extremely close together may get out of order by such a sort, which might not matter.
