Jos Collin a620966969 port: updated PhysicalCoreID() 
Summary:
Updated PhysicalCoreID() to use sched_getcpu() on x86_64 for glibc >= 2.22.  Added a new
function named GetCPUID() that calls sched_getcpu(), to avoid repeated code. This change is done as per the comments of PR: https://github.com/facebook/rocksdb/pull/2230

Signed-off-by: Jos Collin <jcollin@redhat.com>
Closes https://github.com/facebook/rocksdb/pull/2260

README 

This directory contains interfaces and implementations that isolate the
rest of the package from platform details.

Code in the rest of the package includes "port.h" from this directory.
"port.h" in turn includes a platform specific "port_<platform>.h" file
that provides the platform specific implementation.

See port_posix.h for an example of what must be provided in a platform
specific header file.
