rsapce interrupt notification generally takes a lot more cycles
than kernel, so one-shot interrupt is used here to guarantee minimum
overhead and DPDK polling thread returns to polling mode immediately
once it receives an interrupt notificaiton for incoming packet.

Add three dev_ops functions to enable and disable rx queue interrupts; and to
retrieve the vector num which the specified queue assosiated with.

- split rte_intr_wait_rx_pkt into two function, wait and set.
- rewrite rte_intr_rx_wait/rte_intr_rx_set to remove queue visibility on eal.
- rte_intr_rx_wait to support multiplexing.
- allow epfd as input to support flexible event fd combination.
v5
To make bsd compiling happy with new intr changes.

Per vector event fd will store in rte_intr_handle during init.
Device drivers take responsibility to fill queue-vec mapping table(vec_num[]).

v5 changes
Add two API *rte_intr_rx_wait* and *rte_intr_rx_set* for RX interrupt.
They're only available in VFIO_MSIX.

Cunming Liang (5):
eal: declare new interrupt api

eal/linux: add per rx queue interrupt handling based on VFIO
ethdev: add rx interrupt enable/disable functions

These two patches are the fixing for the compling error when
CONFIG_RTE_BUILD_SHARED_LIB=y.
The root cause is *per_lcore__socket_id* and *rte_sys_gettid* are missing in
the version map.
Thanks for the notification from Tetsuya Mukawa .

In non-EAL thread, lcore_id alrways be LCORE_ID_ANY.
It cann't be used as unique id for recursive spinlock.
Then use rte_gettid() to replace it.

For those none EAL thread, *_lcore_id* shall always be LCORE_ID_ANY.
The libraries using *_lcore_id* as index need to take care.

by rte_thread_set_affinity()

For those non-EAL thread, *_lcore_id* is invalid and probably larger than
RTE_MAX_LCORE.
The patch adds the check and allows only EAL thread using EAL per thread log
level and log type.
Others shares the global log level.
