a0990ee416 arch: Remove the duplicated up_tls_info implementation
Define up_tls_info in arch/arch.h directly if the general one isn't suitable

2882551299 Correct a comment
Fix comment in libs/libc/tls/tls_getinfo.c:  The TLS data must lie at the beginning of the allocated stack memory for both push-up and push-down stacks.

a4218e2144 include/nuttx/sched.h: Make naming of all internal names consistent:
1. Add internal scheduler functions should begin with nxsched_, not sched_
2. Follow the consistent naming patter of https://cwiki.apache.org/confluence/display/NUTTX/Naming+of+OS+Internal+Functions

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.

bda24f09c2 libs/libc/tls/tls_getinfo.c: Add tls_get_info()
Move the logic to get TLS information from an inline function to a normal function.  For the unaligned case, it is probably too large to be inlined.

Also fixes some minor things from review of previous commits.
