/**
 * bytestring - simple bytestring handling
 *
 * This code handles manipulation of "bytestrings" represented as a
 * structure containing a pointer and length.  Bytestrings are not
 * NUL-terminated, and may include internal \0 characters.  The main
 * use case is for referencing sub-sections of a large data buffer
 * without the inconvenience of manually passing (and returning) both
 * pointer and length all the time.
 *
 * Because of this use case, the bytestrings are treated as having
 * immutable contents (we use a const char pointer).  The caller code
 * is responsible for ensuring that the lifetime of the data
 * referenced by the bytestrings is long enough not to leave
 * bytestring structures with a dangling pointer.
 *
 * Example:
 *	const char buf[] = "ABCDEFGH";
 *	struct bytestring abcd = BYTESTRING("ABCD");
 *
 *	assert(bytestring_eq(bytestring(buf, 4), abcd));
