When attempting to scan hugepages, signal to the eal that an error has
occurred, rather than performing a panic.
If we fail to acquire hugepage information, simply signal an error to
the application. This clears the run_once counter, allowing the user or
application to take a corrective action and retry.

There may be no way to gracefully recover, but the application
should be notified that a failure happened, rather than completely
aborting. This allows the user to proceed with a "slow-path" type
solution.
After this change, the EAL CPU NUMA node resolution step can no longer
emit an rte_panic. This aligns with the code in rte_eal_init, which
expects failures to return an error code.

Downstreams might want to provide different DPDK releases at the same
time to support multiple consumers of DPDK linked against older and newer
sonames.
Also due to the interdependencies that DPDK libraries can have applications
might end up with an executable space in which multiple versions of a
library are mapped by ld.so.
Think of LibA that got an ABI bump and LibB that did not get an ABI bump
but is depending on LibA.
Application
\-> LibA.old
\-> LibB.new -> LibA.new
That is a conflict which can be avoided by setting CONFIG_RTE_MAJOR_ABI.
If set CONFIG_RTE_MAJOR_ABI overwrites any LIBABIVER value.
An example might be ``CONFIG_RTE_MAJOR_ABI=16.11`` which will make all
libraries librte<?>.so.16.11 instead of librte<?>.so.<LIBABIVER>.
We need to cut arbitrary long stings after the .so now and this would work
for any ABI version in LIBABIVER:
$(Q)ln -s -f $< $(patsubst %.$(LIBABIVER),%,$@)
But using the following instead additionally allows to simplify the Make
File for the CONFIG_RTE_NEXT_ABI case.
$(Q)ln -s -f $< $(shell echo $@ | sed 's/\.so.*/.so/')

Allow the BAR setup to succeed if a device has at least 1 BAR region
defined. Previously, the device probe would only succeed if at least one
memory BAR existed, but there are devices that have only port I/O BARs.
For example, on Virtual Box a virtio device has only a single I/O BAR
because by default MSI-X is not enabled. While in qemu/kvm the virtio
device has MSI-X enabled and therefore has both an I/O and Memory BAR.

The variable optind should be reset to one not zero.
From the man page:
"The variable optind is the index of the next element to be processed in
argv. The system initializes this value to 1.
The caller can reset it to 1 to restart scanning of the same argv, or when
scanning a new argument vector.”
The problem I saw with my application was trying to parse the wrong
option, which can happen as DPDK parses the first part of the command line
and the application parses the second part. If you call getopt() multiple
times in the same execution, the behavior is not maintained when using
zero for optind.

The code indentation in the example app files used spaces rather than
tabs for indentation, and as such did not conform to DPDK conventions.
This left those modifying the code in a bind - to fix things on a line
by line basis so as to avoid checkpatch errors, or to keep things
consistent within the file, and accept checkpatch errors.
Since these files have not had too many changes since the original
import, there is little change history to lose by doing a complete
reformatting of the code, so just update all indentation to standard.
In the process, wrap long lines appropriately, avoiding splitting
error messages.

Since splitting these strings makes it difficult to search for logs it is

of the LONG_LINE_STRINGS to the list of exceptions will allow lines that
end with a string to exceed the maximum line length, but lines that end
with variables or other constructs will still be flagged as errors. Also,
lines that make use of PRIx64 with string concatenation will still be
flagged if the beginning of the last string fragment begins after the 80

Since "make test" and "make test-build" does dependency resolving, they
check for all dependent components (lib and drivers) which takes a few
seconds.
This is a good feature during development, but if the target is only
running unit test, that step is unnecessary, it is possible to compile
once and run unit test multiple times, without checking any code update.
For this purpose, a new make rule "make test-basic" added. Which only
runs the unit test, expects that unit test already compiled.

"make test" <--- Updated functionality (build + run basic tests)
Now "make test" builds all tests and runs unit test (test).
Thanks to dependency resolving, it is possible to call "make test"
directly after config, "make test" will compile dependent components
(lib and drivers, but not apps).
And a new "make test-build" make rule added which will build
tests but not run unit test. "make test-build" has same dependency
resolving features with "make test"
To include "test" folder into makesystem, existing ROOTDIRS- variable
is used instead of hardcoding folder name into makefiles, current usage
of ROOTDIRS* variables are:
