mem: revert to using flock and add per-segment lockfiles
The original implementation used flock() locks, but was later
switched to using fcntl() locks for page locking, because
fcntl() locks allow locking parts of a file, which is useful
for single-file segments mode, where locking the entire file
isn't as useful because we still need to grow and shrink it.
However, according to fcntl()'s Ubuntu manpage [1], semantics of
fcntl() locks have a giant oversight:
This interface follows the completely stupid semantics of System
V and IEEE Std 1003.1-1988 (“POSIX.1”) that require that all
locks associated with a file for a given process are removed
when any file descriptor for that file is closed by that process.
This semantic means that applications must be aware of any files
that a subroutine library may access.
Basically, closing *any* fd with an fcntl() lock (which we do because
we don't want to leak fd's) will drop the lock completely.
So, in this commit, we will be reverting back to using flock() locks
everywhere. However, that still leaves the problem of locking parts
of a memseg list file in single file segments mode, and we will be
solving it with creating separate lock files per each page, and
tracking those with flock().
We will also be removing all of this tailq business and replacing it
with a simple array - saving a few bytes is not worth the extra
hassle of dealing with pointers and potential memory allocation
failures. Also, remove the tailq lock since it is not needed - these
fd lists are per-process, and within a given process, it is always
only one thread handling access to hugetlbfs.
So, first one to allocate a segment will create a lockfile, and put
a shared lock on it. When we're shrinking the page file, we will be
trying to take out a write lock on that lockfile, which would fail if
any other process is holding onto the lockfile as well. This way, we
can know if we can shrink the segment file. Also, if no other locks
are found in the lock list for a given memseg list, the memseg list
fd is automatically closed.
One other thing to note is, according to flock() Ubuntu manpage [2],
upgrading the lock from shared to exclusive is implemented by dropping
and reacquiring the lock, which is not atomic and thus would have
created race conditions. So, on attempting to perform operations in
hugetlbfs, we will take out a writelock on hugetlbfs directory, so
that only one process could perform hugetlbfs operations concurrently.

bus/dpaa: optimize physical to virtual address search
With Hotplugging memory support, the order of memseg has been changed

depend on PA to VA address conversion for I/O.
This patch creates a list of blocks requested to be pinned to the

Crypto requires physical to virtual address conversion for

assumption now stands invalid with memory hotplugging support.

mbuf: support attaching external buffer
This patch introduces a new way of attaching an external buffer to a mbuf.
Attaching an external buffer is quite similar to mbuf indirection in
replacing buffer addresses and length of a mbuf, but a few differences:
- When an indirect mbuf is attached, refcnt of the direct mbuf would be
2 as long as the direct mbuf itself isn't freed after the attachment.
In such cases, the buffer area of a direct mbuf must be read-only. But
external buffer has its own refcnt and it starts from 1. Unless
multiple mbufs are attached to a mbuf having an external buffer, the
external buffer is writable.
- There's no need to allocate buffer from a mempool. Any buffer can be
attached with appropriate free callback.
- Smaller metadata is required to maintain shared data such as refcnt.

vhost: revert avoid concurrency when logging dirty pages
This reverts commit
394313fff39d0f994325c47f7eab39daf5dc9e11.
While the patch did solve concurrency issue, it induces more
pages copies as some clean pages are marked as dirty for
performance reasons. Moreover, as there is no more contention
doing the logging, the rate of packets than can be processed is
higher, leading to even more pages to be dirtied.
It has been reported that with more than one queue pair, and
with a relatively low packet rate (1Mpps), the live migration
never converges until the flow is stopped.
While a better solution is found, it is better to reset to the
old behaviour, i.e. using atomic operation for dirty pages
logging.

ethdev: add group jump action
Add jump action type which defines an action which allows a matched
flow to be redirect to the specified group. This allows physical and
logical flow table/group hierarchies to be defined through rte_flow.
This breaks ABI compatibility for the following public functions (as it
modifes the ordering of the rte_flow_action_type enumeration):
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()
Add support for specification of new JUMP action to testpmd's flow
cli, and update the testpmd documentation to describe this new
action.

ethdev: add tunnel encap/decap actions
Add new flow action types and associated action data structures to
support the encapsulation and decapsulation of VXLAN and NVGRE tunnel
endpoints.
The RTE_FLOW_ACTION_TYPE_[VXLAN/NVGRE]_ENCAP action will cause the
matching flow to be encapsulated in the tunnel endpoint overlay
defined in the [vxlan/nvgre]_encap action data.
The RTE_FLOW_ACTION_TYPE_[VXLAN/NVGRE]_DECAP action will cause all
headers associated with the outer most tunnel endpoint of the specified
type for the matching flows.

net/sfc: do not use RSS context if it is not required
RSS action with only one destination queue and no specific settings
for hash types and key does not require dedicated RSS context and
may be simplified to QUEUE action.

net/tap: return empty port offload capabilities
Fix internal report on port specific offload capabilities to be 0 (no
capabilities). Before this commit port capabilities were a clone of queue
capabilities, however the current TAP offload capabilities (e.g.
checksum calculation) are per queue and are not specific per port.
This commit fixes an internal validation check for new configured
queue offloads.
The port capability API keeps reporting all queue capabilities as port
capabilities.

net/ixgbe: add support for representor ports
Add support for virtual function representor ports to the ixgbe PF
driver. When SR-IOV virtual functions devices are enabled a
corresponding representor port for each VF can be enabled in the
process in which the ixgbe PMD is running within, by specifying the
representor devargs with the list of VF ports that representors
are to be created for.
An example of the devargs which would create VF representor for virtual
functions 0,2,4,5,6 and 7 is:
-w DBDF,representor=[0,2,4-7]
