Addresses #1736, #1398  Move extern declaration of STRADDLE_HACK_INSIDE_CALLBACK from cachetable.c to cachetable.h to allow build on Windows.

Addresses #1736, #1398 When inside straddle_hack callback don't use normal rwlock_read_lock for get_and_pin, but simply increment reader count instead. This prevents deadlock where callback waits for end_checkpoint to release write lock, but while end_checkpoint waits for callback to release read lock.

Closign and opening a cachefile is now threadsafe (race condition when trying to open during a close).
If race condition hits, it will stall the open till the close is done.
All opens are now single threaded.  This can be improved if it causes a bottleneck.

Added comments for possible future race conditions after lock refinement.

When a new brt is open, it takes over responsibilities of all existing zombie brts, and closes them.
When a brt closes, if other brts exist, it passes off responsibilities and closes immediately.  It only becomes a zombie if no other brts exist.

(Everything above is in context of a single header).

Addresses #1691 Further fixes to a race condition where refcounts in a cachefile were not protected by any lock.
See [11371] removed most of the causes of this (by limiting the places where refcount was edited).
Now (cachefile) refcounts are protected by the cachetable_lock.
