5bf7c185af semphore: release all semphores' holder that the task held when exit 
Add a list in TCB to track all semphores the task held, so we
can release all holders when exit, so nxsched_verify_tcb
is unnecessary.

5c80b94820 Replace #include <semaphore.h> to #include <nuttx/semaphore.h> 
Since the kernel side should call nxsem_xxx instead and remove the unused inclusion

cf99fb40c9 This commit moves all of the libraries under a common directory called libs/. This most certainly break libcxx and uClibc++ for now. 
Squashed commit of the following:

    libs/libxx:  Fix some confusing in naming.  If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
    libs/:  Fix paths in moved library directories.
    libs:  Brute force move of libc, libnx, and libxx to libs.  Cannot yet build it in that configuration.
