When executing an MRET instruction, MIE is set to MPIE.
In order to branch to up_sigdeliver() with interrupts disabled,
we need to change MPIE, not MIE.
and remove the special handling in the stack dump

PR #1450 broke the Cygwin build. Refer to Issue #1672.
The use of of logic like:
EXTRA_LIBPATHS += -L "${dir ${shell $(CC) $(ARCHCPUFLAGS) --print-file-name=libgcc.a}}"
fails when the Toolchain $(CC) is a native Windows toolchain. That is because the returned path is a Windows-style patch which cannot be handled by the make 'dir' command. Commit 4910d43ab0 reorganized a lot of definitions and replaced the correct code with the use of the limit make 'dir' command. The original code used the Bash dirname command which does not suffer from this limitation; it can handle both POSIX and Windows paths.
This was verified using the stm32f4discover:nsh toolchain with the Windows native ARM Embedded toolchain. That toolchain returns:
arm-none-eabi-gcc --print-file-name=libgcc.a
c:/program files (x86)/gnu tools arm embedded/9 2019-q4-major/bin/../lib/gcc/arm-none-eabi/9.2.1/libgcc.a
1.It make sense to let Toolchain.defs give the default value
2.The board can still change if the default isn't suitable
3.Avoid the same definition spread more than 200 Make.defs

- 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.
Mac OS X was renamed to macOS at some point. Update references to
OSX, OS X, Mac OS X, Mac OSX, and other permutations, to macOS,
in README files and in comments of other files.
* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
