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.

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

Update to the fix for Issue #436 - UdpClass renamed to UDP and the constructor moved into the .cpp to prevent compilation errors in certain conditions if w5100.h hasn't been included before Udp.h

Fixes to UDP so that it no longer has socket 0 hardcoded - all part of issue #436 . UdpClass::begin now finds the first available free socket, or fails if they're all in use. UdpClass::stop added to release the socket once it is no longer needed. The global Udp object has also been removed and the examples updated to provide their own instance. Finally, in testing I noticed that the UdpNtpClient didn't print leading 0s if the minute or second was a single-digit, so have taken the opportunity to provide a simple fix for it.
