75583b0d1e eal: add keep alive monitoring
Adds functions for detecting and reporting the live-ness of LCores,
the primary requirement of which is minimal overheads for the
core(s) being checked. Core failures are notified via an application
defined callback.

b0fb5155f8 kni: use utsrelease to determine Ubuntu kernel version
/proc/version_signature is the version for the host machine, but in
e.g., chroots, this does not necessarily match that DPDK is built
for. DPDK will then build for the wrong kernel version - that of the
server, and not that installed in the (build) chroot.

The patch uses utsrelease.h from the kernel sources instead and fakes
the upload version.

Tested on a server with Ubuntu 12.04, building in a chroot for Ubuntu
14.04.

4c02e453cc eal: introduce SMP memory barriers
This commit introduce rte_smp_mb(), rte_smp_wmb() and rte_smp_rmb(), in
order to enable memory barriers between lcores.
The patch does not provide any functional change for IA, the goal is to
have infrastructure for weakly ordered machines like ARM to work on DPDK.
