This adds the inital wiring for i2c bus support in the sim target
and for Linux host adds the lower half that uses the i2c chardev.

## Summary of Changes
Add a host timer that generates periodic signals and sends SIGALRM to
the process that runs the NuttX simulation. This logic is integrated as
part of the existing NuttX oneshot timer. The host timer installs an
irq handler which is expected to run every CONFIG_USEC_PER_TICK .

1. There is difference about symbol replace on nuttx-names.in
between MacOS & Linux
2. For MacOS, if open '-fvisibility=hidden' and adjust nuttx-names.in,
it will meet symbol link-back-to-nuttx error.
3. Make the MacOS replace behaviour, same with Linux
Note:
MacOS should install objcopy with command:
$ brew install binutils
$ export PATH=$PATH:/usr/local/opt/binutils/bin
already check in to cibuild.sh

EXTRAFLAGS is already applied to *FLAGS in board's Make.defs (and
it applies to whole build, not just arch-code). EXTRAFLAGS is passed
around each make call to the complete build.
KDEFINE is already added to EXTRAFLAGS in main Makefile so no need
to add it again in arch-level Makefile
Make.dep file should be updated by .config changed after first make.
There are 2 cases affected for this problem:
1) Add source files by config symbol
2) Include header files in #ifdef directive
These 2 cases may not be included in Make.dep and this may prevent the
differential build from working correctly.
make can't guarantee the build order of prerequest with -jn where n > 1

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

On modern environments, bss is not executable.
Alternatively we can use the ARCH_HAVE_MODULE_TEXT mechanism.
But it's considered overkill for the sim, which is mainly
for development.
The benefit include:
1. Simplify the implementation
2. Support both tick and tickless automatically
3. No time drift in tickless mode
4. Support critmon arch API automatically
The benefits include:
1. Simplify the implementation
2. Support Ctrl+C automatically
3. Support poll automatically
4. Call pm_activity automatically
5. Save one polling thread
* ld doesn't have --start-groupi/--end-group things. As far as I know,
it works that way by default.
* objcopy with Mach-O support is not widely available.
(GNU binutils seem to claim the support but it didn't actually work
for me. llvm-objcopy --redefine-syms explicitly rejects Mach-O.)
Instead, use -unexported_symbols_list linker flag to hide symbols
to avoid conflicts with host symbols.
