9fca820459 compressdev: remove driver name from logs
The logs printed by COMPRESSDEV_LOG were prefixed with the driver name.

In order to avoid assigning the driver before the end of the probing,
the driver name is removed from the compressdev library logs.

f8e9989606 remove useless constructor headers
A constructor is usually declared with RTE_INIT* macros.
As it is a static function, no need to declare before its definition.
The macro is used directly in the function definition.

0260571c99 compressdev: add huffman encoding flags
Added Huffman fixed and dynamic encoding feature flags,
so an application can query if a device supports
these two types, when performing DEFLATE compression.

a6531d58b4 compressdev: replace mbuf scatter gather flag
The current mbuf scatter gather feature flag is
too ambiguous, as it is not clear if input and/or output
buffers can be scatter gather mbufs or not.

Therefore, three new flags will replace this flag:
- RTE_COMP_FF_OOP_SGL_IN_SGL_OUT
- RTE_COMP_FF_OOP_SGL_IN_FB_OUT
- RTE_COMP_FF_OOP_LB_IN_SGL_OUT

Note that out-of-place flat buffers is supported by default
and in-place is not supported by the library.

7385d1c4b4 compressdev: clarify when private xform can be cleared
As the private_xform data can be shared by many operations
and across queue_pairs, it would be performance impacting
for PMDs to track inflights associated with one. It makes
more sense to push the responsibility to the application to
keep track of its usage and only delete the private_xform when
there are no more ops using it.

0d6717c437 compressdev: support hash operations
- Added hash algo enumeration and params in xform and rte_comp_op
- Updated compress/decompress xform to input hash algorithm
- Updated struct rte_comp_op to input hash buffer

User in capability query will know about support hashes via
device info comp_feature_flag. If supported, application can initialize
desired algorithm enumeration in xform structure and pass valid hash
buffer during enqueue_burst().
