- Fix broken definition of IsBoostAllowed which would cause ERESOURCE boosts to be applied backwards.

- Use cleaner, inlined definitions for ExAcquire/ReleaseResourceLock.
- Convert ERESOURCE code to use a Queued In-Stack Spinlock instead of a regular spinlock.
- Force usage of the spinlock instead of cli/sti for DBG builds, and enable strict sanity checks.
- Fix incorrect check in ExpCheckForApcsDisabled.
- Properly handle memory starvation in the contended path.
- Make sure to allocate a semaphore if needed during ExAcquireSharedStarveExclusive.
- Fix multiple bugs in ExIsResourceAcquiredSharedLite.
- ExReleaseResourceForThreadLite didn't always properly set the ResourceOwnedExclusive flag, and didn't validate ownership.
- ExSetResourceOwnerPointer wouldn't set the owner if there wasn't one already.
