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.

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

After previous commit, add -fvisibility=hidden, we don't need
worry about depended libxx.so callback to nuttx symbol in SIM.
So most of the symbol in nuttx-names.in can be remove.
But we still need some symbol replacement for host code.
Host code should call host API if access HOST sth, for example:
open, close, accept, printf...

## Summary of changes
The pthread_cond_* API is also present as part of libfs.a and we want
to avoid colisions and link with the correct implementation.
