Amaury Denoyelle f58b2698ce MEDIUM: proxy: add lock for global accesses during proxy free
Define a new lock with label PROXIES_DEL_LOCK. Its purpose is to protect
operations performed on global lists or trees while a proxy is freed.

Currently, this lock is unneeded as proxies are only freed on
single-thread init or deinit. However, with the incoming dynamic backend
deletion, this operation will be also performed at runtime, outside of
thread isolation.
