95bad38c5b Canonicalize symlinks in portnames 
This allows users to supply symlinks created e.g. by udev rules instead
of the actual device names.

aee7d69195 Fix ERROR_SEM_TIMEOUT issue on Windows. 
The sp_blocking_write() call was incorrectly returning an error upon
ERROR_SEM_TIMEOUT. It now returns 0 instead.

888fb45d66 Fix sp_blocking_read_next() implementation on Windows. 
A ReadFile() call needed to check the actual number of bytes read,
instead of assuming all requested bytes were read.

34442106ef windows: Set fAbortOnError=FALSE. 
Since we're not handling and clearing receive errors (framing, parity and
overrun), we should turn them off to avoid crashing out with
ERROR_OPERATION_ABORTED in various calls if they occur. Invalid data
will then simply not end up in the buffer. This is consistent with our
current behaviour on posix/termios systems.

It might be nice to be able to inform calling code about receive errors, but I
can't see a good way to do this in a cross-platform way at the moment.

This fixes (parts of) bug #341.

e31f2c6b8b Fix free() of uninitialized pointer. 
Explicitly set port->usb_path to NULL, otherwise a free(port->usb_path)
can happen where port->usb_path is uninitialized.

This closes bug #512.

call and also eliminates the need for the non-standard typeof() call.
