23df14d1ba devargs: restore empty devargs
Following commit c07691ae10, an implicit change has been done in the
devargs API.
This triggers problem in virtual pmds that did not check for parameters
validity as it was implicitely valid.

Fix this by restoring the empty argument as "" and add a note in the api.
Restore associated tests.

Fixes: c07691ae10 ("devargs: remove limit on parameters length")

e89ae122ce app/test: fix misplaced braces in strncmp
One occurrence call to strncmp had the closing brace in the wrong
place. Changing this form:
	if (strncmp(X, Y, sizeof(X) != 0))
which does a comparison of length 1, to
	if (strncmp(X, Y, sizeof(X)) != 0)
which does the correct length comparison and then compares the result
to zero in the "if" part.

Seen with clang-3.5:
  "error: size argument in 'strncmp' call is a comparison"

This patch is similar to 261386248 but it looks that one occurrence
was forgotten.

2613862481 app/test: fix misplaced braces in devargs check
This patch fixes two occurrences where a call to strncmp had the closing
brace in the wrong place. Changing this form:
	if (strncmp(X,Y,sizeof(X) != 0))
which does a comparison of length 1, to
	if (strncmp(X,Y,sizeof(X)) != 0)
which does the correct length comparison and then compares the result to
zero in the "if" part, as the author presumably originally intended.

a8b97e3a1d devargs: use a comma instead of semicolon to separate key/values
This commit changes the API of --use-device command line argument.
It changes the separators from ';' to ','. Indeed, ';' is not the best
choice as this character is also used to separate shell commands,
forcing the user to surround arguments with quotes.

This commit impacts both devargs and kvargs as each of them define
a separator in --use-device argument:

- devargs defines the separator between the device name or pci_id and
   its arguments
- kvargs defines the separator between each key/value pairs in
   arguments for drivers using the kvargs API to parse their arguments

The modification of devargs and kvargs is done in one commit to keep
the coherency of --use-device.

bf6dea0e04 devargs: introduce API and test
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
./app/test -c 0x15 -n 3 -m 64
RTE>>eal_flags_autotest
[...]
Test OK
