preliminary file redirection support for IAR #58

I did some file redirection support for IAR. I don't have the expertise to test this properly (it seems to compile, and should get called) It is modeled after the gcc support.

Sorry I missed to test it with file redirection enabled. It is currently rife with compilation errors. Please wait a little while and I will fix it :)

There, I have a starting point. I tested this with component: CMSIS-Compiler:File Interface:Custom and - file: ../template/file_interface/retarget_fs.c and it seems to compile.

I removed errno handling, the gcc one looked like it had the incorrect sign anyways. And it is really unclear whose responsibility it is to set these. (IAR errno.h doesn't have POSIX codes anyways)

Thanks for providing PR!. I'll review and try to test making sure that we have a working solution.
