* fxload sample provenance
* No need for <sys/types.h> in samples as already in libusb.h
* Don't bother about sscanf_s in xusb
* Use HAVE_### and rely on config.h where possible
* Formal inclusion of <winsock.h> in libusb.h for WinCE and WDK
* Cleanup of Windows' config.h
* Avoid ENAMETOOLONG and ENOTEMPTY conflict between errno.h and winsock.h for WinCE
* Additional newlines & braces cleanup
* cleanup_test_output() produced an assertion error when compiled with MSVC
due to closing ctx->output_file
* set ctx->output_file to stdout by default
