9798674f27 libc: add support for reallocarray
This commit adds support for reallocarray function. The functionality
is the same as for standard realloc, but the function also checks for
multiplication overflow and fails safely in case it occurs.

622677d4a1 libc: Implement exit, atexit, on_exit and cxa_exit on the user side
For CONFIG_BUILD_KERNEL using the sched/task/task_exithook implementation
will just not work. It calls user code with kernel privileges which is
a bit of a security issue.

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.
