- restrict the unittests SVM address space to what is supported by ASan
- mark SVM mmap()ed address space accessible for ASan
- SVM shared memory heap scheme means some allocation can happen
outside the current process. Lazily mark those accessible for ASan

Rb-trees are no longer maintained in the segment so we don't need to
reserve memory. Keeping the option as a means to avoid underlying infra
(dlmalloc) and alignment overhead.

Type: refactor
Switch from a wrapped byte space to a "continuous" one wherein fifo
chunks are appended to the fifo as more data is enqueued and chunks are
removed as data is dequeued.
The fifo is still subject to a maximum size, i.e., maximum number of
bytes that can be enqueued, so the max number of chunks associated to
the fifo is also constrained.
When enqueueing data, which must fit within the available free space, if
not enough "supporting" chunk memory is available, the fifo asks the
fifo segment for enough chunk memory to ensure that the write can
succeed. To avoid allocating large amounts of small chunks due to small
writes, if possible, the size of the chunks requested is lower capped by
min_alloc.
When dequeuing data, all the chunks that have been completely drained,
i.e., head moved beyond the chunks’ end bytes, are unlinked from the
fifo and returned to the fifo segment. The one exception to this is the
last chunk which is never unlinked.

Avoid tracking with rbtrees all of the chunks associated to a fifo.
Instead, only track chunks when doing out-of-order operations (peek or
ooo enqueue).

The mheap allocator has been turned off for several releases. This
commit removes the cmake config parameter, parallel support for
dlmalloc and mheap, and the mheap allocator itself.

- when the fifo is wrapped, and if applicable, insert a new chunk after
the tail-chunk and rebuild the rb_tree.
- make sure that this new algorithm can be applied only when the fifo is
used by a single thread (master-thread of the fifo).

All instances of test_and_set locks used the following sequence
to release the locks:
CLIB_MEMORY_BARRIER ();
p->lock = 0; // p is a generic struct with a TAS lock
Use clib_atomic_release to generate more efficient assembly code.
