fix(sync): Destroy condition variables - #2004
Merged
Merged
Conversation
Add cross-platform condition-variable cleanup and invoke it when thread pools, background workers, flush tasks, and app-hang monitors are released. Condition variables may own implementation-specific resources, and POSIX requires destroying an initialized condition variable before reinitializing it. Close the semaphore and event handles owned by the pre-Vista emulation. Update synchronization tests to clean up their condition variables. Keep the task-queue notification under its predicate mutex so teardown cannot race with an in-flight signal.

Brings in fb337fb (getsentry#2004). The only conflict was CHANGELOG.md, where both getsentry#2004 and this branch appended an entry to the same Unreleased "Fixes" list; both entries are kept, with getsentry#2004 first since it is already on master.
