b73cf39d94 Moving write errors out of return value into separate API methods.
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.

8059abe581 write(), print(), and println() now return number of bytes written.
The type is long, and negative values indicate errors.  Needs more testing.
