ethdev: get registers width

The ethtool app was allocating too little space for 64-bit
registers which resulted in memory corruption.

Removes hard-coded assumption that device registers
are always 32 bits wide. The rte_eth_dev_get_reg_length
and rte_eth_dev_get_reg_info callbacks did not
provide register size to the app in any way while is
needed to allocate correct number of bytes before
retrieving registers using rte_eth_dev_get_reg.

This commit changes rte_eth_dev_get_reg_info so that
it can be used to retrieve both the number of registers
and their width, and removes the now-redundant
rte_eth_dev_get_reg_length.

drivers: update registration macro usage

Modify the PMD_REGISTER_DRIVER macro, adding a name argument to it. The
addition of a name argument creates a token that can be used for subsequent
macros in the creation of unique symbol names to export additional bits of
information for use by the pmdinfogen tool. For example:

PMD_REGISTER_DRIVER(ena_driver, ena);

registers the ena_driver struct as it always did, and creates a symbol
const char this_pmd_name0[] __attribute__((used)) = "ena";

which pmdinfogen can search for and extract. The subsequent macro

DRIVER_REGISTER_PCI_TABLE(ena, ena_pci_id_map);

creates a symbol const char ena_pci_tbl_export[] __attribute__((used)) =
"ena_pci_id_map";

Which allows pmdinfogen to find the pci table of this driver

Using this pattern, we can export arbitrary bits of information.

pmdinfo uses this information to extract hardware support from an object
file and create a json string to make hardware support info discoverable
later.

ethdev: check queue state before starting or stopping

Following the same approach taken with dev_started field
in rte_eth_dev_data structure, this patch adds two new fields
in it, rx_queue_state and tx_queue_state arrays, which track
which queues have been started and which not.

This is important to avoid trying to start/stop twice a queue,
which will result in undefined behaviour
(which may cause RX/TX disruption).

Mind that only the PMDs which have queue_start/stop functions
have been changed to update this field, as the functions will
check the queue state before switching it.
