This commit copies some functions of asynchronous transactions for MIDI
capture, to merge scs1x module. The features of payload in asynchronous
transaction are:
* System exclusive messages for SCS.1 are encoded without ID data. In
this encoding scheme, 4 bits in LSB are available. The bits are squashed
in payload byte. Thus, one payload byte transfers two MIDI messages.
* The first byte of payload byte means:
* 0x00: depending on second payload byte
* 0xf9: including escaped system exclusive messages for SCS.1, up to
3 byte (= 6 MIDI messages)
* the others: including MIDI 1.0 messages
* the others: including escaped system exclusive messages for SCS.1, up
to 64 bytes
