While having the ability to run a test based off the DPDK_TEST
environment variable is useful, it's sometimes more convenient to
specify the test name as a commandline parameter to a test binary.
This patch adds support for checking all parameters after the EAL ones, and
running all valid autotests requested - either from DPDK_TEST or on the
commandline. This also allows multiple tests to be run in a single
automated session, which is useful for working with components which have
multiple test suites.

Since all other apps have been moved to the "app" folder, the autotest app
remains alone in the test folder. Rather than having an entire top-level
folder for this, we can move it back to where it all started in early
versions of DPDK - the "app/" folder.
This move has a couple of advantages:
* This reduces clutter at the top level of the project, due to one less
folder.
* It eliminates the separate build task necessary for building the
autotests using make "make test-build" which means that developers are
less likely to miss something in their own compilation tests
* It re-aligns the final location of the test binary in the app folder when
building with make with it's location in the source tree.
For meson builds, the autotest app is different from the other apps in that
it needs a series of different test cases defined for it for use by "meson
test". Therefore, it does not get built as part of the main loop in the
app folder, but gets built separately at the end.

This is to logically group unit tests into their own folder,

Hopefully this will make the unit test in DPDK more visible.

A bug has been detected by valgrind:
Invalid write of size 1
by 0x86ECC76: sprintf (in /usr/lib/libc-2.23.so)
by 0x430B0A: commands_init (in build/app/test)
by 0x42F215: main (in build/app/test)
Address 0x9d72ff2 is 0 bytes after a block of size 1,346 alloc'd
at 0x78C1BD0: malloc (in vgpreload_memcheck-amd64-linux.so)
by 0x430AE4: commands_init (in build/app/test)
by 0x42F215: main (in build/app/test)
The commands buffer is exactly 1346 B long so there is an access just
after the buffer. The sprintf always writes '\0' at the end of the string.
The '#' separator adds 1 B more to each string. This is correct until the
last string is sprinted there. The last one is 1 B longer then expected,
i.e.:
strlen(t->command) + strlen("#") + ONE_FOR_ZERO

The unit test can be used to measure cycles per packet in different rx/tx routines.
The NIC works in loopback mode. So it doesn't require test equipment to measure throughput.
As result, the unit test shows the average cycles per packet consuming.
When doing the test, make sure the link is UP.
Usage Example:
1. Run unit test app in interactive mode
app/test -c f -n 4 -- -i
2. Run and wait for the result
pmd_perf_autotest
There's option to choose rx/tx pair, default is vector.
set_rxtx_mode [vector|scalar|full|hybrid]
Note: To get acurate scalar fast, please choose 'vector' or 'hybrid' without INC_VEC=y in config
It supports to measure standalone rx or tx.
Usage Example:
Choose rx or tx standalone, default is both
set_rxtx_anchor [rxtx|rxonly|txonly]
It also supports to measure standalone RX burst cycles.
In this way, it won't repeat re-send received packets.
Now it measures two situations, poll before/after xmit(w or w/o desc. cache conflict)
Usage Example:
Set stream control mode, by default is continuous
set_rxtx_sc [continuous|poll_before_xmit|poll_after_xmit]

The rte_pktmbuf structure was initially included in the rte_mbuf
structure. This was needed when there was 2 types of mbuf (ctrl and
packet). As the control mbuf has been removed, we can merge the
rte_pktmbuf into the rte_mbuf structure.
Advantages of doing this:
- the access to mbuf fields is easier (ex: m->data instead of m->pkt.data)
- make the structure more consistent: for instance, there was no reason
to have the ol_flags field in rte_mbuf
- it will allow a deeper reorganization of the rte_mbuf structure in the
next commits, allowing to gain several bytes in it

The initial role of rte_ctrlmbuf is to carry generic messages (data
pointer + data length) but it's not used by the DPDK or it applications.
Keeping it implies:
- loosing 1 byte in the rte_mbuf structure
- having some dead code rte_mbuf.[ch]
This patch removes this feature. Thanks to it, it is now possible to
simplify the rte_mbuf structure by merging the rte_pktmbuf structure
in it. This is done in next commit.

* Updated patch to HEAD.
* Modified patch to retain the old function names for ctrl mbufs as

work following this change.

This commit introduces a new API for storing device arguments given by
the user. It only adds the framework and the test. The modification of
EAL to use this new module is done in next commit.
The final goals:
- unify pci-blacklist, pci-whitelist, and virtual devices arguments
in one file
- allow to register a virtual device driver from a dpdk extension
provided as a shared library. For that we will require to remove
references to rte_pmd_ring and rte_pmd_pcap in argument parsing code
- clarify the API of eal_common_whitelist.c, and rework its code that is
often complex for no reason.
- support arguments for PCI devices and possibly future non-PCI devices
(other than virtual devices) without effort.
Test result:
echo 100 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
echo 100 > /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages

These library changes provide a new Intel DPDK feature for communicating
with virtual machines using QEMU's IVSHMEM mechanism.
The feature works by providing a command line for QEMU to map several hugepages
into a single IVSHMEM device. For the guest to know what is inside any given IVSHMEM
device (and to distinguish between Intel(R) DPDK and non-Intel(R) DPDK IVSHMEM
devices), a metadata file is also mapped into the IVSHMEM segment. No work needs to
be done by the guest application to map IVSHMEM devices into memory; they are
automatically recognized by the Intel(R) DPDK Environment Abstraction Layer (EAL).
Changes in this patch:
* Changes to EAL to allow mapping of all hugepages in a memseg into a single file
* Changes to EAL to allow ivshmem devices to be transparently mapped in
the process running on the guest.
* New ivshmem library to create and manage metadata exported to guest VM's
* New ivshmem compilation targets
* Mempool and ring changes to allow export of structures to a VM and allow
a VM to attach to those structures.
* New autotests to unit tests this functionality.
