The intended usage is explained in the cover email (see below) and demonstrated
in the test supplied in the following patch - when sending arrays of pointers
between cores as it happens in a forwarding example.

I have added macros to help find the parameters and I have added mempool
functions that allow you to determine if you can use the mempool and
what params it needs. The new mempool functions are mentioned in the
docs for ptr compress.

It's useful information to dump. Maybe consider adding something akin to
RTE_LIBRTE_MEMPOOL_STATS to gate this in case the prints are

I think that a misconception that arch specific optimizations (such as SIMD
code) required stuff to go into EAL has been prevailing, and this misconception
is a main reason why EAL has become so bloated.

* disable NEON and SVE implementation on AARCH32 due to wrong pointer size
v6:
* added example usage to commit message of the initial commit
v7:
* rebase to remove clashing mailmap changes
v8:
* put ptr compress into its own library
* add depends-on tag
* remove copyright bumps

memory address. Offsets can be stored in fewer bytes (dictated
by the memory region size and alignment of the pointer).
For example: an 8 byte aligned pointer which is part of a 32GB
memory pool can be stored in 4 bytes.

. Added more bulk sizes to showcase their effects
on compression. Adjusted loop iteration numbers to take into account

Adjusted old printfs to match new ones which have aligned numbers.
