b8320b9824 pci: use lookup tailq api
There is no reason why we should use the "reserve" tailq api, since the pci
entry is already statically reserved.

c0ce0577e8 pci: consolidate address comparisons
This patch replaces pci_addr_comparison() and memcmp() of pci addresses by
rte_eal_compare_pci_addr().

To compare PCI addresses, rte_eal_compare_pci_addr() doesn't use memcmp().
This is because sizeof(struct rte_pci_addr) returns 6, but actually
this structure is like below.

struct rte_pci_addr {
        uint16_t domain;                /**< Device domain */
        uint8_t bus;                    /**< Device bus */
        uint8_t devid;                  /**< Device ID */
        uint8_t function;               /**< Device function. */
};

If the structure is dynamically allocated in a function without bzero,
last 1 byte may have value. As a result, memcmp may not work.
To avoid such a case, rte_eal_compare_pci_addr() compare following values.

        dev_addr = (addr->domain << 24) | (addr->bus << 16) |
                                (addr->devid << 8) | addr->function;

699d55e3ff eal/bsd: fix pci mapping in secondary process
On FreeBSD, when initializing a secondary process,
EAL was complaining if there were ports not bound
to nic_uio module, exiting the application, which
should not happen, as this is expected behaviour,
and not an error

6f41fe75e2 eal: deprecate rte_snprintf
The function rte_snprintf serves no useful purpose. It is the
same as snprintf() for all valid inputs. Deprecate it and
replace all uses in current code.

Leave the tests for the deprecated function in place.

6bf883260d pci: distinguish between legitimate failures and non-fatal errors
Currently, EAL does not distinguish between actual failures and expected
initialization errors. E.g. sometimes the driver fails to initialize
because it was not supposed to be initialized in the first place, such
as device not being managed by said driver.

This patch makes EAL fail on actual initialization errors while still
skipping over expected initialization errors.

3031749c2d remove trailing whitespaces
This commit removes trailing whitespace from lines in files. Almost all
files are affected, as the BSD license copyright header had trailing
whitespace on 4 lines in it [hence the number of files reporting 8 lines
changed in the diffstat].

d3e6faf840 pci: rework interrupt fd init and fix fd leak

Fix this by closing fd unconditionnally in this function and open the
