mem: do not use lockfiles for single file segments mode
Due to internal glibc limitations [1], DPDK may exhaust internal
file descriptor limits when using smaller page sizes, which results
in inability to use system calls such as select() by user
applications.
Single file segments option stores lock files per page to ensure
that pages are deleted when there are no more users, however this
is not necessary because the processes will be holding onto the
pages anyway because of mmap(). Thus, removing pages from the
filesystem is safe even though they may be used by some other
secondary process. As a result, single file segments mode no
longer stores inordinate amounts of segment fd's, and the above
issue with fd limits is solved.
However, this will not work for legacy mem mode. For that, simply
document that using bigger page sizes is the only option.

This me
bus: introduce device level DMA memory mapping
The DPDK APIs expose 3 different modes to work with memory used for DMA:
1. Use the DPDK owned memory (backed by the DPDK provided hugepages).
This memory is allocated by the DPDK libraries, included in the DPDK
memory system (memseg lists) and automatically DMA mapped by the DPDK
layers.
2. Use memory allocated by the user and register to the DPDK memory
systems. Upon registration of memory, the DPDK layers will DMA map it
to all needed devices. After registration, allocation of this memory
will be done with rte_*malloc APIs.
3. Use memory allocated by the user and not registered to the DPDK memory
system. This is for users who wants to have tight control on this
memory (e.g. avoid the rte_malloc header).
The user should create a memory, register it through rte_extmem_register
API, and call DMA map function in order to register such memory to
the different devices.
The scope of the patch focus on #3 above.
Currently the only way to map external memory is through VFIO
(rte_vfio_dma_map). While VFIO is common, there are other vendors
which use different ways to map memory (e.g. Mellanox and NXP).
The work in this patch moves the DMA mapping to vendor agnostic APIs.
Device level DMA map and unmap APIs were added. Implementation of those
APIs was done currently only for PCI devices.
For PCI bus devices, the pci driver can expose its own map and unmap
functions to be used for the mapping. In case the driver doesn't provide
any, the memory will be mapped, if possible, to IOMMU through VFIO APIs.
Application usage with those APIs is quite simple:
* allocate memory
* call rte_extmem_register on the memory chunk.
* take a device, and query its rte_device.
* call the device specific mapping function for this device.
Future work will deprecate the rte_vfio_dma_map and rte_vfio_dma_unmap
APIs, leaving the rte device APIs as the preferred option for the user.

mk: use linux and freebsd in config names
Rather than using linuxapp and bsdapp everywhere, we can change things to
use the, more readable, terms "linux" and "freebsd" in our build configs.
Rather than renaming the configs we can just duplicate the existing ones
with the new names using symlinks, and use the new names exclusively
internally. ["make showconfigs" also only shows the new names to keep the
list short] The result is that backward compatibility is kept fully but any
new builds or development can be done using the newer names, i.e. both
"make config T=x86_64-native-linuxapp-gcc" and "T=x86_64-native-linux-gcc"
work.

eal: restrict control threads to startup CPU affinity
Spawning the ctrl threads on anything that is not part of the eal
coremask is not that polite to the rest of the system, especially
when you took good care to pin your processes on cpu resources with
tools like taskset (linux) / cpuset (freebsd).
Rather than introduce yet another eal options to control on which cpu
those ctrl threads are created, let's take the startup cpu affinity
as a reference and remove the eal coremask from it.
If no cpu is left, then we default to the master core.
The cpuset is computed once at init before the original cpu affinity
is lost.
Introduced a RTE_CPU_AND macro to abstract the differences between linux
and freebsd respective macros.
Examples in a 4 cores FreeBSD vm:

test: move to app directory
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.
