core: add CVE IDs in ChangeLog

A relay client could send data with no end-of-line (an unterminated method
or header line) and dribble its payload, making WeeChat accumulate it in the
partial message buffer that grew without limit, until all memory was
exhausted. This path is reachable before authentication during websocket
initialization with the "weechat" and "irc" protocols.

The accumulated partial message is now bounded by
RELAY_HTTP_PARTIAL_MESSAGE_MAX_LENGTH: once the limit is reached, the extra
data is ignored.
