Subject: [PATCH] socks: return error if hostname too long for remote resolve
Prior to this change the state machine attempted to change the remote
resolve to a local resolve if the hostname was longer than 255
characters. Unfortunately that did not work as intended and caused a
security issue.
Name resolvers cannot resolve hostnames longer than 255 characters.
Bug: https://curl.se/docs/CVE-2023-38545.html

Subject: [PATCH] cookie: remove unnecessary struct fields
Plus: reduce the hash table size from 256 to 63. It seems unlikely to
make much of a speed difference for most use cases but saves 1.5KB of
data per instance.
Closes #11862
