This method originally flushed pending input bytes, which makes sense in
Stream. At some point it was changed to flush output bytes instead, but
it was never moved to Print to reflect this.
Since Stream inherits from Print, this should not really affect any
users of the Stream or Print classes. However to prevent problems with
existing implementations of the Print class that do not provide a
flush() implementation, a default implementation is provided. We should
probably remove this at some point in the future, though.
The new function just calls Print::write(const uint8_t *, size_t), but
this allows writing out a buffer of chars (without having to learn about
casts).
write(), print(), println() now return size_t (and don't use negative values to signal errors).
Print adds writeError() for checking for write errors, clearWriteError() to reset the flag to false, and a protected setWriteError() for signalling errors.

- moving back to multple cores per platform
- using target instead of platform
- moving per-board and per-programmer preferences out of Preferences.java and into a new Target class
- adding a new "target" preference
- support for platform:value values in board preferences for bootloader path and core
- XXX: need to support platform:value syntax for board upload.using preferences.
