Add a new function to detect address of a libc
symbol of a function that could be intercepted.
With the address detector in GetRealLibcAddress(),
an optional interceptor of libc call will be bypassed.

Switch the following functions to libc calls:

- internal_mmap()
- internal_munmap()
- internal_mprotect()
- internal_close()
- internal_open()
- internal_read()
- internal_write()
- internal_ftruncate()
- internal_stat()
- internal_lstat()
- internal_fstat()
- internal_dup2()
- internal_readlink()
- internal_unlink()
- internal_rename()
- internal_sched_yield()
- internal__exit()
- internal_sleep()
- internal_execve()
- NanoTime()
- internal_clock_gettime()
- internal_waitpid()
- internal_getpid()
- internal_getppid()
- internal_getdents()
- internal_lseek()
- internal_sigaltstack()
- internal_fork()
- internal_sigprocmask()

This revision leaves room for refactoring in subsequent commits.
