c3ee68b879 mempool: rename populate functions to IOVA
The functions rte_mempool_populate_phys() and
rte_mempool_populate_phys_tab() are renamed to
rte_mempool_populate_iova() and rte_mempool_populate_iova_tab().
The deprecated functions are kept as aliases to avoid breaking the API.

12b8cc1a7e mempool: notify memory area to pool
HW pool manager e.g. Octeontx SoC demands s/w to program start and end
address of pool. Currently, there is no such api in external mempool.
Introducing rte_mempool_ops_register_memory_area api which will let HW(pool
manager) to know when common layer selects hugepage:
For each hugepage - Notify its start/end address to HW pool manager.

a0fd91cefc mempool: rename functions with confusing names
The mempool_count and mempool_free_count behaved contrary to what their
names suggested. The free_count function actually returned the number of
elements that were allocated from the pool, not the number unallocated as
the name implied.

Fix this by introducing two new functions to replace the old ones,
* rte_mempool_avail_count to replace rte_mempool_count
* rte_mempool_in_use_count to replace rte_mempool_free_count

In this patch, the new functions are added, and the old ones are marked
as deprecated. All apps and examples that use the old functions are
updated to use the new functions.

Fixes: af75078fec ("first public release")

4b5062755a mempool: allow user-owned cache
The mempool cache is only available to EAL threads as a per-lcore
resource. Change this so that the user can create and provide their own
cache on mempool get and put operations. This works with non-EAL threads
too. This commit introduces the new API calls:

    rte_mempool_cache_create(size, socket_id)
    rte_mempool_cache_free(cache)
    rte_mempool_cache_flush(cache, mp)
    rte_mempool_default_cache(mp, lcore_id)

Changes the API calls:

    rte_mempool_generic_put(mp, obj_table, n, cache, flags)
    rte_mempool_generic_get(mp, obj_table, n, cache, flags)

The cache-oblivious API calls use the per-lcore default local cache.

656f2d3ede mempool: deprecate specific get and put functions
This commit introduces the API calls:

    rte_mempool_generic_put(mp, obj_table, n, is_mp)
    rte_mempool_generic_get(mp, obj_table, n, is_mc)

Deprecates the API calls:

    rte_mempool_mp_put_bulk(mp, obj_table, n)
    rte_mempool_sp_put_bulk(mp, obj_table, n)
    rte_mempool_mp_put(mp, obj)
    rte_mempool_sp_put(mp, obj)
    rte_mempool_mc_get_bulk(mp, obj_table, n)
    rte_mempool_sc_get_bulk(mp, obj_table, n)
    rte_mempool_mc_get(mp, obj_p)
    rte_mempool_sc_get(mp, obj_p)

449c49b93a mempool: support handler operations
Until now, the objects stored in a mempool were internally stored in a
ring. This patch introduces the possibility to register external handlers
replacing the ring.

The default behavior remains unchanged, but calling the new function
rte_mempool_set_ops_byname() right after rte_mempool_create_empty() allows
the user to change the handler that will be used when populating
the mempool.

This patch also adds a set of default ops (function callbacks) based
on rte_ring.

c042ba2067 mempool: rework support of Xen dom0
Avoid to have a specific file for that, and remove #ifdefs.
Now that we have introduced a function to populate a mempool
with a virtual area, the support of xen dom0 is much easier.

The only thing we need to do is to convert the guest physical
address into the machine physical address using rte_mem_phy2mch().
This function does nothing when not running xen.

d86046f0cf mempool: use the list to iterate the elements
Now that the mempool objects are chained into a list, we can use it to
browse them. This implies a rework of rte_mempool_obj_iter() API, that
does not need to take as many arguments as before. The previous function
is kept as a private function, and renamed in this commit. It will be
removed in a next commit of the patch series.

The only internal users of this function are the mellanox drivers. The
code is updated accordingly.

Introducing an API compatibility for this function has been considered,
but it is not easy to do without keeping the old code, as the previous
function could also be used to browse elements that were not added in a
mempool. Moreover, the API is already be broken by other patches in this
version.

The library version was already updated in
commit 213af31e09 ("mempool: reduce structure size if no cache needed")

8dcb12707e mempool: uninline function to check cookies
There's no reason to keep this function inlined. Move it to
rte_mempool.c. We need to export the function for when compiling
with shared libraries + debug. We also need to keep the macro,
because we don't want to call an empty function when debug is
disabled.
