rbutil: Merge rbutil with utils folder.

Browse source 
rbutil uses several components from the utils folder, and can be
considered part of utils too. Having it in a separate folder is an
arbitrary split that doesn't help anymore these days, so merge them.

This also allows other utils to easily use libtools.make without the
need to navigate to a different folder.

/**
* Decompresses an LZSS stream.
*
* Input bytes will be read in as necessary using the system->read()
* function with the input file handle given. This will continue until
* system->read() returns 0 bytes, or an error. Errors will be passed
* out of the function as MSPACK_ERR_READ errors. Input streams should
* convey an "end of input stream" by refusing to supply all the bytes
* that LZSS asks for when they reach the end of the stream, rather
* than return an error code.
*
* Output bytes will be passed to the system->write() function, using
* the output file handle given. More than one call may be made to
* system->write().
*
* As EXPAND.EXE (SZDD/KWAJ), Microsoft Help and QBasic have slightly
* different encodings for the control byte and matches, a "mode"
* parameter is allowed, to choose the encoding.
*
* @param system an mspack_system structure used to read from
* the input stream and write to the output
* stream, also to allocate and free memory.
* @param input an input stream with the LZSS data.
* @param output an output stream to write the decoded data to.
* @param input_buffer_size the number of bytes to use as an input
* bitstream buffer.
* @param mode one of #LZSS_MODE_EXPAND, #LZSS_MODE_MSHELP or
* #LZSS_MODE_QBASIC
* @return an error code, or MSPACK_ERR_OK if successful
