We're planning to merge buffer content locks into BufferDesc.state. To reduce the size of that patch, centralize calls to BufferDescriptorGetContentLock(). The biggest part of the change is in assertions, by introducing BufferIsLockedByMe[InMode]() (and removing BufferIsExclusiveLocked()). This seems like an improvement even without aforementioned plans. Additionally replace some direct calls to LWLockAcquire() with calls to LockBuffer().
