cryptodev: add queue pair reset API

The API will reset the specific queue pair of a cryptodev.
The current API, cryptodev_queue_pair_setup(), requires the cryptodev
to be stopped before reconfiguring any queue pair. Stopping the
cryptodev in one thread can result in a segmentation fault when
multiple queues are used for enqueue and dequeue operations.

On supported PMDs, the cryptodev_queue_pair_reset() will
reconfigure/reset the queue pair without affecting other queues or
the cryptodev state.

The caller should ensure that there are no enqueue or dequeue operations
ongoing on that queue and that there are no inflight packets before
calling this API.

use C linkage where appropriate in headers

Assure that 'extern "C" { /../ }' do not cover files included from a
particular header file, and address minor issues resulting from this

use C linkage where appropriate in headers

Assure that 'extern "C" { /../ }' do not cover files included from a
particular header file, and address minor issues resulting from this
change of order.

Dealing with C++ should delegate to the individual include file level,
rather than being imposed by the user of that file. For example,
forcing C linkage prevents __Generic macros being replaced with
overloaded static inline functions in C++ translation units.

Eliminate 'extern "C"' from files which do not declare any symbols
(e.g., only macros or struct types).

On the other hand, the headers check is too naive in assuming that all
headers must contain a 'extern "C"'. Such a check was added in commit
1ee492bdc4ff ("buildtools/chkincs: check missing C++ guards").
Since this current change results in many headers not containing such
a token, remove the check for 'extern "C"' until we have a better
implementation.

cryptodev: add hash algorithms in asymmetric capability

Most of the asymmetric operations start with hash of the input.
But a PMD might also support only plain input (eg openssl).
Add a new field in asymmetric capability to declare support
for hash operations that PMD can support for the asymmetric
operations. Application can skip computing hash if PMD already
supports it.

cryptodev: drop export of internal tracepoints

The file rte_cryptodev_trace.h contains tracepoints which are internal to
the cryptodev library. This file is renamed to cryptodev_trace.h, and is
made an internal header. The tracepoints in this file are removed from the
experimental and internal section in version.map file.
