Completes the Implementation of the TLS-based errno

Browse Source 
- 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.

Description: In NuttX, the errno value is unique for each thread. But for
bug-for-bug compatibility, the same errno should be shared by
the task and each thread that it creates. It is *very* easy
to make this change: Just move the pterrno field from
struct tcb_s to struct task_group_s. However, I am still not
sure if this should be done or not.
to make this change: Just move the tls_errno field from
struct tls_info_s to struct task_group_s. However, I am still
not sure if this should be done or not.
NOTE: glibc behaves this way unless __thread is defined then,
in that case, it behaves like NuttX (using TLS to save the
thread local errno).
