There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'

Ensure all lists of drivers are standardized:
* one driver per line
* lists double-indented with spaces (as they are line continuations)
* elements in alphabetical order
* opening and closing list brackets "[" & "]" on own lines
* last element has trailing comma
Any code snippets in the list files is adjusted to single-indent using
whitespace to correspond to the new style also.
The lists of standard library dependencies per class, and other short
lists are not formatted one-per-line as these lists are not expected to

Two simplifications can be made to the build file which reduce indentation
levels and make it easier to read:
1. When meson build support was first added, the compat library existed in
DPDK as a single header file. Since that header has been merged into EAL,
we no longer need to support header-only libraries, so can shorten the
code.
2. From meson 0.49 onwards we have the "continue" keyword available to
break out of one loop iteration and begin the next. This allows us to
remove blocks in the build configuration file which were conditional on the
"build" variable being true. Instead we can use "continue" to abort
processing at the point where the "build" value becomes false.
Since this patch changes the indentation level of large parts of the
meson.build file, we use the opportunity to adjust the whitespace used to
the meson-standard 4-spec indentation level.

KNI runs userspace callback with rtnl lock held, this is not working
fine with some devices that needs to interact with kernel interface in
the callback, like Mellanox devices.
The solution is releasing the rtnl lock before calling the userspace
callback. But it requires two consideration:
1. The rtnl lock needs to released before 'kni->sync_lock', otherwise it
causes deadlock with multiple KNI devices, please check below the A.
for the details of the deadlock condition.
2. When rtnl lock is released for interface down event, it cause a
regression and deadlock, so can't release the rtnl lock for interface
down event, please check below B. for the details.
As a solution, interface down event is handled asynchronously and for
all other events rtnl lock is released before processing the callback.
A. KNI sync lock is being locked while rtnl is held.
If two threads are calling kni_net_process_request() ,
then the first one will take the sync lock, release rtnl lock then sleep.
The second thread will try to lock sync lock while holding rtnl.
The first thread will wake, and try to lock rtnl, resulting in a
deadlock. The remedy is to release rtnl before locking the KNI sync
lock.
Since in between nothing is accessing Linux network-wise, no rtnl
locking is needed.
B. There is a race condition in __dev_close_many() processing the
close_list while the application terminates.
It looks like if two KNI interfaces are terminating,
and one releases the rtnl lock, the other takes it,
updating the close_list in an unstable state,
causing the close_list to become a circular linked list,
hence list_for_each_entry() will endlessly loop inside
__dev_close_many() .
To summarize:
request != interface down : unlock rtnl, send request to user-space,
wait for response, send the response error code to caller in user-space.
request == interface down: send request to user-space, return immediately
with error code of 0 (success) to user-space.

Each table entry is made up of match fields and action data, with the
latter made up of the action ID and the action arguments. The approach
of having the user specify explicitly the endianness of the action
arguments is difficult to be picked up by P4 compilers, as the P4
compiler is generally unaware about this aspect.
This commit introduces the auto-detection of the endianness of the
action arguments by examining the endianness of the their destination:
network byte order (NBO) when they get copied to headers and host byte
order (HBO) when they get copied to packet meta-data or mailboxes.
The endianness specification of each action argument as part of the
rule specification, e.g. H(...) and N(...) is removed from the rule
file and auto-detected based on their destination. The DMA instruction
scope is made internal, so mov instructions need to be used. The
pattern of transferring complete headers from table entry action args
to headers is detected, and the associated set of mov instructions
plus header validate is internally detected and replaced with the
internal-only DMA instruction to preserve performance.

The SWX pipeline instructions work with operands of different types:
header fields (h.header.field), packet meta-data (m.field), extern
object mailbox field (e.obj.field), extern function (f.field), action
data read from table entries (t.field), or immediate values; hence the
HMEFTI acronym. The H operands are stored in network byte order (NBO),
while the MEFT operands are stored in host byte order (HBO), hence the
need to operate endianness conversions.
Some of the endianness conversion macros were not working correctly
for some cases such as operands of different sizes, and they are fixed
now. Affected instructions: mov, and, or, xor, jmpeq, jmpneq.

In case an event from a previous stage is required to be forwarded
to a crypto adapter and PMD supports internal event port in crypto
adapter, exposed via capability
RTE_EVENT_CRYPTO_ADAPTER_CAP_INTERNAL_PORT_OP_FWD, we do not have
a way to check in the API rte_event_enqueue_burst(), whether it is
for crypto adapter or for eth tx adapter.
Hence we need a new API similar to rte_event_eth_tx_adapter_enqueue(),
which can send to a crypto adapter.
Note that RTE_EVENT_TYPE_* cannot be used to make that decision,
as it is meant for event source and not event destination.
And event port designated for crypto adapter is designed to be used
for OP_NEW mode.
Hence, in order to support an event PMD which has an internal event port
in crypto adapter (RTE_EVENT_CRYPTO_ADAPTER_OP_FORWARD mode), exposed
via capability RTE_EVENT_CRYPTO_ADAPTER_CAP_INTERNAL_PORT_OP_FWD,
application should use rte_event_crypto_adapter_enqueue() API to enqueue
events.
When internal port is not available(RTE_EVENT_CRYPTO_ADAPTER_OP_NEW mode),
application can use API rte_event_enqueue_burst() as it was doing earlier,
i.e. retrieve event port used by crypto adapter and bind its event queues
to that port and enqueue events using the API rte_event_enqueue_burst().
