[ROSAUTOTEST]

- Flush cout after each write as already done by Colin in r66855, per ROSTESTS-158
- Use DbgPrint instead of OutputDebugStringA again because the latter only calls the former anyway
Fixes test summary lines not being recognized by Testman, especially on VMware.

A little summary so we don't keep going back and forth with this function:
1) Only writing complete lines is required to that the output doesn't mix with debug output from other components. See r55618
2) OutputDebugStringA splits its input into 512-byte-sized blocks with no regard for line breaks, so using it with strings larger than 512 bytes breaks (1).
3) OutputDebugStringA eventually calls DbgPrint("%s", string) anyway so using it with chunks smaller than 512 bytes is not an optimization
As a result, yes this function MUST split up the lines itself, this can't be optimized or simplified away! kthxbye
