[PATCH v4 5/7] app/testpmd: use space separator in dump commands

[Thomas Monjalon <thomas@monjalon.net>]

In order to make dump commands look like other commands
which have keywords separated with space,
replace these commands:
	- dump_physmem
	- dump_socket_mem
	- dump_memzone
	- dump_struct_sizes
	- dump_ring [name]
	- dump_mempool [name]
	- dump_devargs
	- dump_lcores
	- dump_trace
	- dump_log_types
with these ones:
	- dump physmem
	- dump socket_mem
	- dump memzone
	- dump struct_sizes
	- dump ring [name]
	- dump mempool [name]
	- dump devargs
	- dump lcores
	- dump trace
	- dump log_types

Both parsing functions (with and without name argument)
are merged together.

The function cmd_dump_init() is removed
as it seems useless to define tokens at runtime.
