The "reserve" macros and functions do not check if the requested entry is free.
They do nothing more than the lookup function (which itself "creates" entries
...).
The rte_tailq api is marked as "internal use" in documentation and these macros
are only used in test application, so just get rid of them.

Theres no need to export this variable. Its set and queried from an API call
that doesn't exist in the hot path. Instead just export the rte_socket_id
symbol and make the variable private to protect it from type changes. We should
do this with the other exported variables too, but I think its too late in the
release cycle to do that.
tested using distributor_autotest (which uses rte_socket_id), successfully.
Only tested on linux, as I don't currently have a bsd system spun up, but the
changes are symmetric, and should be fine

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;
