(1) Add --enable-uti option. The binary-patch library is
preloaded with this option.
(2) Binary-patching is done by syscall_intercept developed by Intel
This commit includes the following fixes:
(1) Fix do_exit() and terminate() handling
(2) Fix timing of killing mcexec threads when McKernel thread calls terminate()

Instead of parsing System.map, use kallsyms_lookup_name() to
get unexported symbols addresses at module loading time.
This lets mckernel work with kaslr enabled (it gets enabled by
default from el7.5 onwards)

This is a response to a CEA's request.
- The tools directory is created under the mckernel directory.
- Some include files are now installed in the install directory,
but we should rethink of it.
1. Fix OOM: Count memory usage only when allocation succeeded
2. Fix OOM: Make user allocation fail when memory is running out
3. Fix OOM: Move rusage_init() before numa_init()
4. Cleanup: Rename ihkconfig/ihkosctl functions
5. Cleanup: Pass event type to eventfd()
6. Cleanup: arch/.../rusage.h --> arch/.../arch_rusage.h
1. User asks mcctrl for the result via ihk_os_getrusage() with passing void *
2. mcctrl compiles the results and passes them to the user
3. User interprets it by using the type defined in the LWK-specific header
This evals 4.12.5-300.fc26.x86_64 right away, which is necessary for e.g.
the variable used for System.map detection.
(looking at history, ihk always had double-quotes while mckernel always
had singles quotes -- this looks like a manual copy typo?)
When rebooting:
1. Stop irqbalance
2. Modify /proc/irq/*/smp_affinity so that McKernel cores are not
included
3. Start irqbalance with McKernel cores and IHK IRQ banned from
load balancing
When stopping:
1. Stop irqbalance
2. Restore /proc/irq/*/smp_affinity
3. Restart irqbalance with the system default settings
