1. segment manager would attempt to balance the usages across
the segments, when it allocate fifos
2. the memory presure level is determined per fifo-segment
3. updated unit test
4. updated cli output for segments

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.

Also make sure that size for dlmalloc allocated private segments is
accurate.

Type: fix
- make sure that chunks and the rbtree are initialized if fifo segment
allocates multiple chunks for the fifo.
- ensure head/tail chunks are updated on all enqueue/dequeue events,
including when dropping data.
- more unit tests
Also fixes dequeue drop updates of head chunk.

- track fifo segment free and chunk freelist memory
- improve fifo alloc. If there are enough chunks to satisfy a fifo
allocation request but not enough free memory, allocate a multi-chunk
fifo
- add apis to preallocate chunks and fifo headers
- more tests

Default chunk is no longer embedded into the fifo and on free is
returned to its respective chunk list.
