With this commit, we allow the user to set other_config:dpdk-init=true
after the process is started. This makes it easier to start Open
vSwitch with DPDK using standard init scripts without restarting the
service.
This is still far from ideal, because initializing DPDK might still
abort the process (e.g. if there not enough memory), so the user must
check the status of the process after setting dpdk-init to true.
Nonetheless, I think this is an improvement, because it doesn't require
restarting the whole unit.

DPDK documentation is recently updated to reflect that DPDK does not
hold any references to, nor take ownership of, the argv/argc elements.
With that understanding, let's just release the memory asap.

The DPDK EAL library intents that all argc/argv arguments passed on the
command line will be in the form:
progname dpdk arguments program arguments
This means the argv array will look something like:
argv[0] = progname
argv[1..x] = dpdk arguments
argv[x..y] = program arguments
When the eal initialization routine completes, it will modify the argv array
to set argv[ret] = progname, such that the arguments can then be passed to
something like getopts for further processing.
When the dpdk arguments rework was initially added, the assignment mentioned
above was not considered. This means two errors were introduced:
1. Leak of the element at argv[ret]
2. Double-free of the element at argv[0]

The rte_pdump header file was not included in the file that requires it.
Fix this.

There's a lot of code in netdev-dpdk which is not at all related to the
netdev interface, mostly the library initialization code.
This commit moves it to a new 'dpdk' module, to simplify 'netdev-dpdk'.
Also a new module 'dpdk-stub' is introduced to implement some functions
when DPDK is not available. This replaces the old 'netdev-nodpdk'
module.
Some redundant includes are removed or reorganized as a consequence.
No functional change.
