/*
* TLS/TSD-agnostic macro-based implementation of thread-specific data. There
* are four macros that support (at least) three use cases: file-private,
* library-private, and library-private inlined. Following is an example
* library-private tsd variable:
*
* In example.h:
* typedef struct {
* int x;
* int y;
* } example_t;
* #define EX_INITIALIZER JEMALLOC_CONCAT({0, 0})
* malloc_tsd_protos(, example, example_t *)
* malloc_tsd_externs(example, example_t *)
* In example.c:
* malloc_tsd_data(, example, example_t *, EX_INITIALIZER)
* malloc_tsd_funcs(, example, example_t *, EX_INITIALIZER,
* example_tsd_cleanup)
*
* The result is a set of generated functions, e.g.:
*
* bool example_tsd_boot(void) {...}
* example_t **example_tsd_get() {...}
* void example_tsd_set(example_t **val) {...}
*
* Note that all of the functions deal in terms of (a_type *) rather than
* (a_type) so that it is possible to support non-pointer types (unlike
* pthreads TSD). example_tsd_cleanup() is passed an (a_type *) pointer that is
* cast to (void *). This means that the cleanup function needs to cast *and*
* dereference the function argument, e.g.:
*
* void
* example_tsd_cleanup(void *arg)
* {
* example_t *example = *(example_t **)arg;
*
* [...]
* if ([want the cleanup function to be called again]) {
* example_tsd_set(&example);
* }
* }
*
* If example_tsd_set() is called within example_tsd_cleanup(), it will be
* called again. This is similar to how pthreads TSD destruction works, except
* that pthreads only calls the cleanup function again if the value was set to
* non-NULL.

* Allocation class interface
*
* When requesting an object from the allocator, the first step is to determine
* which allocation class best approximates the size of the object.
* Once found, the appropriate free list, called bucket, for that
* class is selected in a fashion that minimizes contention between threads.
* Depending on the requested size and the allocation class, it might happen
* that the object size (including required metadata) would be bigger than the
* allocation class size - called unit size. In those situations, the object is
* constructed from two or more units (up to 64).
*
* If the requested number of units cannot be retrieved from the selected
* bucket, the thread reaches out to the global, shared, heap which manages
* memory in 256 kilobyte chunks and gives it out in a best-fit fashion. This
* operation must be performed under an exclusive lock.
* Once the thread is in the possession of a chunk, the lock is dropped, and the
* memory is split into units that repopulate the bucket.
*
* These are the CTL entry points that control allocation classes:
* - heap.alloc_class.[class_id].desc
* Creates/retrieves allocation class information
*
* It's VERY important to remember that the allocation classes are a RUNTIME
* property of the allocator - they are NOT stored persistently in the pool.
* It's recommended to always create custom allocation classes immediately after
* creating or opening the pool, before any use.
* If there are existing objects created using a class that is no longer stored
* in the runtime state of the allocator, they can be normally freed, but
* allocating equivalent objects will be done using the allocation class that
* is currently defined for that size.
*
* Please see the libpmemobj man page for more information about entry points.

We assume that instructions are unsigned numbers.
All instructions have an opcode in the first 6 bits.
Instructions can have the following fields:
`A' : 8 bits
`B' : 9 bits
`C' : 9 bits
`Bx' : 18 bits (`B' and `C' together)
`sBx' : signed Bx
A signed argument is represented in excess K; that is, the number
value is the unsigned value minus K. K is exactly the maximum value
for that argument (so that -max is represented by 0, and +max is
represented by 2*max), which is half the maximum for the corresponding
unsigned argument.

next open instruction (OP_CALL, OP_RETURN, OP_SETLIST) may use `top'.
(*) In OP_VARARG, if (B == 0) then use actual number of varargs and
set top (like in OP_CALL with C == 0).
(*) In OP_RETURN, if (B == 0) then return up to `top'
(*) In OP_SETLIST, if (B == 0) then B = `top';
if (C == 0) then next `instruction' is real C
(*) For comparisons, A specifies what condition the test should accept
(true or false).

** Implementation of tables (aka arrays, objects, or hash tables).
** Tables keep its elements in two parts: an array part and a hash part.
** Non-negative integer keys are all candidates to be kept in the array
** part. The actual size of the array is the largest `n' such that at
** least half the slots between 0 and n are in use.
** Hash uses a mix of chained scatter table with Brent's variation.
** A main invariant of these tables is that, if an element is not
** in its main position (i.e. the `original' position that its hash gives
** to it), then the colliding element is in its own main position.
** Hence even when the load factor reaches 100%, performance remains good.

*******************************************************************************
* Implementation of (2^1+,2) cuckoo hashing, where 2^1+ indicates that each
* hash bucket contains 2^n cells, for n >= 1, and 2 indicates that two hash
* functions are employed. The original cuckoo hashing algorithm was described
* in:
*
* Pagh, R., F.F. Rodler (2004) Cuckoo Hashing. Journal of Algorithms
* 51(2):122-144.
*
* Generalization of cuckoo hashing was discussed in:
*
* Erlingsson, U., M. Manasse, F. McSherry (2006) A cool and practical
* alternative to traditional hash tables. In Proceedings of the 7th
* Workshop on Distributed Data and Structures (WDAS'06), Santa Clara, CA,
* January 2006.
*
* This implementation uses precisely two hash functions because that is the
* fewest that can work, and supporting multiple hashes is an implementation
* burden. Here is a reproduction of Figure 1 from Erlingsson et al. (2006)
* that shows approximate expected maximum load factors for various
* configurations:
*
* | #cells/bucket |
* #hashes | 1 | 2 | 4 | 8 |
* --------+-------+-------+-------+-------+
* 1 | 0.006 | 0.006 | 0.03 | 0.12 |
* 2 | 0.49 | 0.86 |>0.93< |>0.96< |
* 3 | 0.91 | 0.97 | 0.98 | 0.999 |
* 4 | 0.97 | 0.99 | 0.999 | |
*
* The number of cells per bucket is chosen such that a bucket fits in one cache
* line. So, on 32- and 64-bit systems, we use (8,2) and (4,2) cuckoo hashing,
* respectively.
