ctxlock

Minimal Go read-write-lock with context-cancellation support.

Usage is like symc.RWMutex:

• the Lock must not be copied
• Lock()/Unlock() for write locking
• RLock()/RUnlock() for read locking
• LockCtx(ctx) error for write locking with cancellation
• RLockCtx(ctx) error for read locking with cancellation
• panics on invalid usage (unlocks when not locked, or unlock type not matching lock type)
