net: unify socket into file descriptor

In the current compilation environment, the recursive assignment(=) for compile
flags will be delayed until every file is actually need to be compile.
For example:
--------------------------------------------------------------------------------
arch/arm/src/Makefile:
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)chip}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)common}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)$(ARCH_SUBDIR)}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(TOPDIR)$(DELIM)sched}
CPPFLAGS += $(INCLUDES) $(EXTRAFLAGS)
CFLAGS += $(INCLUDES) $(EXTRAFLAGS)
CXXFLAGS += $(INCLUDES) $(EXTRAFLAGS)
AFLAGS += $(INCLUDES) $(EXTRAFLAGS)
--------------------------------------------------------------------------------
All compilation options will be included recursively,
which will be delayed until the compilation options are actually used:
tools/Config.mk:
--------------------------------------------------------------------------------
define COMPILE
@echo "CC: $1"
$(Q) $(CC) -c $(CFLAGS) $($(strip $1)_CFLAGS) $1 -o $2
endef
--------------------------------------------------------------------------------
All compile flags to be reexecuted $(INCDIR) as long as one file needs to be compiled,
but in fact, the compilation options have not changed in the current directory.
So the we recommand to change the syntax of assignment
From
Recursive (=)
To
Simple (:=)
In this way, we can ensure that all compilation options are expanded only once and reducing repeated works.

from 1 to 2 oherwise pthread_condclockwait will fail

Make.defs under board folder can still overwrite the default as needed

So call 'make EXTRAFLAGS=-Wno-cpp' could suppress the warnings with pre-processor
directive #warning in GCC.

* tools/Config.mk - Add empty definition POSTBUILD
* tools/Makefile.unix/win - Replace CXD56xx specific logic with $(call POSTBUILD)
* boards/arm/cxd56xx/scripts/Config.mk - Add POSTBUILD definitions with logic removed from Makefile.unix/win
* boards/arm/cxd56xx/spresense/scripts/Make.defs - Include the CXD56xx Config.mk immediately after tools/Config.mk so that the empty POSTBUILD definition will be replaced with the correct one
NOTE: There is a precedent for this approach. This is the way that other architecture-specific build options are implemented. See, for example, tools/zds/Config.mk
Kconfig files. Repartition some functionality. Bootloader support will need to be provided in logic under arch/z80/src/ez80 so the critical configuration selections were moved the Kconfig file there.
arch/z80/src/ez80/ez80_i2c.h: Rename arch/z80/src/ez80/ez80f91_i2c.h. It is sharable by both ez80f91 and ez80f92.
arch/z80/src/ez80/: Add logic to perform an additional level of interrupt redirection. This is necessary because the the interrupt handling is part of the loader FLASH-based logic. In order to share interrupts with the program loaded into RAM by the loader, another layer or redirection is required to get control to the interrupt handlers in the loaded program. See ez809f2_loader.asm and ez80f92_program.asm
boards/z80/ez80/z20x/scripts: Reduce size of the interrupt re-direction buffer from 1Kb to 512b.
The SD boot loader was not satisfactory because 1) the SD slot is on an optional board and, hence, cannot be part of a fundamental solution. And 2) it is too big.
The only storage on borard is the Winbond W25 SPI-bsed FLASH. This commit adds support for a bootload to 1) read code in HEX format from a serial port and write it to the W25 FLASH, or 2) read code in binary form from the W25 FLASH into SRAM and execute the loaded program.
boards/z80/ez80/z20x/configs: Added w25boot configuration
boards/z80/ez80/z20x/src: Add bootloader logic, w25_main.c. Add logic to manage shared SRAM memory map so that the loaded program does not clobber the bootloader memory. Add logic to recover the bootloader memory into the heap after the loaded program as started.
boards/z80/ez80/z20x/scripts: Rework scripts and configuration to support a bootloader and program build. The boolloader cannot use all of SRAM; the program must not clobber the SRAM region used by the bootloader.
board/z80/ez80/*/scripts/Make.defs: Fix optimization definition use in assembly flags. It was using the compiler optimization settings instead of the assembler optimization settings. Hence, enabling optimization would could cause assembler command line errors.
arch/z80/src/ez80/Toolchain.defs: Back out some work arounds. Now compiler optimization flags can again set set without assembler command line errors.
boards/z80/ez80/z20x/README.txt: Trivial update to size/optimization discussion.
arch/z80/src/ez80/Toolchain.defs: Update some CFLAGS to match CFLAGS from ZDS-II IDE. Apparently, we must say that the CPU is an eZ80F91 event when compiler for eZ80F92.
boards/z80/ez80/z20x: Update linker scripts.
* tools/zds/zds_Config.mk: Move boards/z80/ez80/scripts/eZ80_Config.mk to tools/zds/zds_Config.mk where it can be shared by other ZDS-II platforms.
* boards/z16/z16f: Duplicate changes for new ZDS-II support from ez80
* boards/z80/z8: Duplicate changes for new ZDS-II support from ez80
* arch/z16/src/z16f/Toolchain.defs: Create required Toolchain.defs file for Z16f
arch/z80/arc/ez80/Toolchain.sh: Move more common toolchain definitions from Make.defs.
boards/z80/ez80/scripts/eZ80_Config.mk: Move common defines that override tools/Config.mk to this new file.
This does not solve the ez80 build problem yet but does assure that when the solution is in place, it will automatically apply to all present and future ez80 configurations.
to avoid shell complain that @echo can't find if the variable expand in the compound
command(e.g. ARLOCK) and remove $(Q) before $AR so the result is almost same as before.
* 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
