948f63f0fd add_handle(): Fix a memory leak. 
This fixes the following scan-build warning:

8d12e620f2 Clarify sp_list_ports() code. 
This also fixes the following scan-build warning:

  serialport.c:335:15: warning: Result of 'malloc' is converted to a
  pointer of type 'struct sp_port *', which is incompatible with sizeof
  operand type 'struct sp_port **'
          if (!(list = malloc(sizeof(struct sp_port **))))

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.

9caa2e86aa Specialise RETURN_VALUE macro into RETURN_{INT,STRING,POINTER}. 
This avoids the need to pass the required format string on every
call and also eliminates the need for the non-standard typeof() call.

do pretty much the same thing.
