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.

devargs: use devargs for vdev and PCI whitelist/blacklist
Remove old whitelist code:
- remove references to rte_pmd_ring, rte_pmd_pcap and pmd_xenvirt in
is_valid_wl_entry() as we want to be able to register external virtual
drivers as a shared library. Moreover this code was duplicated with
dev_types[] from eal_common_pci.c
- eal_common_whitelist.c was badly named: it was able to process PCI
devices white list and the registration of virtual devices
- the parsing code was complex: all arguments were prepended in
one string dev_list_str[4096], then split again
Use the newly introduced rte_devargs to get:
- the PCI white list
- the PCI black list
- the list of virtual devices
Rework the tests:
- a part of the whitelist test can be removed as it is now tested
in app/test/test_devargs.c
- the other parts are just reworked to adapt them to the new API
This commit induce a small API modification: it is not possible to specify
several devices per "--use-device" option. This notation was anyway a bit
cryptic. Ex:
--use-device="eth_ring0,eth_pcap0;iface=ixgbe0"
now becomes:
--use-device="eth_ring0" --use-device="eth_pcap0;iface=ixgbe0"
On the other hand, it is now possible to work in PCI blacklist mode and
instanciate virtual drivers, which was not possible before this patch.

timer: fix TSC frequency by not reading /proc/cpuinfo
This reverts commit
da6fd0759cbeb5fc14991a79e40105b9f6b99059.
"timer: get TSC frequency from /proc/cpuinfo"
The use of cpuinfo to determine the frequency of the TSC is not
advisable and leads to incorrect results when power management is
in use. This is because, while the TSC frequency does not change
in modern cpus with constant_tsc support, the frequency of the core,
and hence the frequency of the core reported by cpuinfo *does* change.
Depending on the current frequency of core 0 when an application is
started, the EAL can get a wildly incorrect value for the TSC freq.
Since frequency is scaled down for power saving, any incorrect value
is likely to be lower than the default, which means that any delay
loops inside the code which rely on the TSC will be shorter than
planned. This can cause issues (reported on the mailing list by a number
of people) where ports are not initialized correctly due to delays being
too short.

However, the code is really way more complex than it needs to be. For

ethdev: fix non-reconfigurable pmd init
Some Poll-Mode Drivers (PMD) are not reconfigurable and,
thus, do not implement (rx|tx)_queue_release functions.
For these drivers, the functions rte_eth_dev_(rx|tx)_queue_config
must return an ENOTSUP error only when reconfiguring,
but not at initial configuration.

mk: fix command-line dependency check for quoted strings
Before recompiling a file, rte.compile-pre.mk checks whether the command
line is different from the previous one.
This is done by storing for each object file the entire command line in a
kind of dependency file with a .cmd extension (see obj2cmd). If that file
exists, the line is retrieved first and compared against $(C_TO_O_STR).
The object file gets recompiled if the file doesn't exist or if the line
is different.
The problem is that sometimes, files are recompiled for no apparent reason.
The check doesn't work properly when a command line contains double-quoted
strings such as -DFOO='"bar"' because the shell interprets and strips them.
This is fixed by protecting C_TO_O_CMD with simple quotes, knowing that
such quotes are already escaped in C_TO_O_STR.

command should be compared against C_TO_O instead.

It ended in impossibilty for GCC to pass parameters to LD.
The prefixed value must override the command line one.

This variable $(O) can be used to specify a build directory
when doing an "install" procedure. The default is ".", which
means that targets will be built in the source dpdk.
This option is useful to compile outside of the source tree that may be
read-only.
