Re: Build errors with inline functions

[Gregory Nutt]

If we want to support the compiler which don't support inline, it's better that:
1.Remove CONFIG_HAVE_INLINE from include/nuttx/compiler.h
2.Convert inline fucntion to macro to normal function
It isn't hard to fix because grep just can find inline about 100 times.
There are inline functions in common C files which are not a problem 
because we have the definitions in compiler.h.  The use in header files 
is causing all of the problems.
