 * A portable @c bool replacement.

 * ::BROTLI_BOOL is a "documentation" type: actually it is @c int, but in API it
 * denotes a type, whose only values are ::BROTLI_TRUE and ::BROTLI_FALSE.
 *
 * ::BROTLI_BOOL values passed to Brotli should either be ::BROTLI_TRUE or
 * ::BROTLI_FALSE, or be a result of ::TO_BROTLI_BOOL macros.
 *
 * ::BROTLI_BOOL values returned by Brotli should not be tested for equality
 * with @c true, @c false, ::BROTLI_TRUE, ::BROTLI_FALSE, but rather should be
 * evaluated, for example: @code{.cpp}
 * if (SomeBrotliFunction(encoder, BROTLI_TRUE) &&

 *   bool x = !!YetAnotherBrotliFunction(encoder, TO_BROLTI_BOOL(2 * 2 == 4));
