Gregory Nutt 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.

arch/x86/src/README.txt
^^^^^^^^^^^^^^^^^^^^^^^

This directory holds x86-specific source files.  All x86 source reside in
lower-level common, chip-specific, and architecture-specific directories.

common/ Directory
^^^^^^^^^^^^^^^^^

This directory holds source files common to all x86 architectures.

Architecture-Specific Directories
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Architecture-specific directories hold common source files shared for by
implementations of specific x86 architectures.

i486
  This directory holds logic appropriate for any instantiation of the 32-bit
  i486 architecture.

Chip-Specific directories
^^^^^^^^^^^^^^^^^^^^^^^^^

The same x86 architecture may be realized in different chip implementations.
For SoC chips, in particular, on-chip devices and differing interrupt
structures may require special, chip-specific definitions in these chip-
specific directories.

qemu
  This is the implementation of NuttX on the QEMU x86 simulation.
