uti: Hook system calls by binary-patching glibc
...
(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()

Prevent one CPU from getting chosen by concurrent forks
...
One CPU could be chosen by concurrent forks because CPU selection and
runq addition are not done atomicly. So this fix makes the two steps
atomic.

debug messages: implement dynamic debug
...
Heavily inspired off linux kernel's dynamic debug:
* add a /sys/kernel/debug/dynamic_debug/control file
(accessible from linux side in /sys/class/mcos/mcos0/sys/kernel/debug/dynamic_debug/control)
* read from file to list debug statements (currently limited to 4k in size)
* write to file with '[file foo ][func bar ][line [x][-[y]]] [+-]p' to change values
Side effects:
* reindented all linker scripts, there is a new __verbose section
* added string function strpbrk
