9ce03b1660 Move pthread-specific data into TLS
1. Move pthread-specific data files from sched/pthread/ to libs/libc/pthread.
2. Remove pthread-specific data functions from syscalls.
3. Implement tls_alloc() and tls_free() with system calls.
4. Reimplement pthread_key_create() and pthread_key_free() using tls_alloc() and tls_free().
5. Reimplement pthread_set_specific() and pthread_get_specicif() using tls_set_value() and tls_get_value()

3dca5eba15 Completes the Implementation of the TLS-based errno
- Remove per-thread errno from the TCB structure (pterrno)
- Remove get_errno() and set_errno() as functions.  The macros are still available as stubs and will be needed in the future if we need to access the errno from a different address environment (KERNEL mode).
- Add errno value to the tls_info_s structure definitions
- Move sched/errno to libs/libc/errno.  Replace old TCB access to the errno with TLS access to the errno.

c2244a2382 Remove CONFIG_TLS
A first step in implementing the user-space error is force TLS to be enabled at all times.  It is no longer optional

b1071cca00 libs/libc/tls/Kconfig: Add CONFIG_TLS_ALIGNED
CONFIG_TLS_ALIGNED will select the (legacy) aligned stack implementation of TLS.  If CONFIG_TLS_ALIGNED is not defined, then the new, implementation of TLS using an unaligned stack will be enabled.

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.
