Leading underscores are ill-advised because such identifiers are reserved. Trailing underscores are merely ugly. Strip both. Our header guards commonly end in _H. Normalize the exceptions. Macros should be ALL_CAPS. Normalize the exception. Done with scripts/clean-header-guards.pl. include/hw/xen/interface/ and tools/virtiofsd/ left alone, because these were imported from Xen and libfuse respectively.
