midi bug in 2.13.58

[胡海鹏 - Hu Haipeng]

Hello,
 Lilypond 2.13.58 still has bug on mid output. Because the max number of instr
is 16, and now the midi output considers every instr instead of track as an
item, the result of program change still causes error. For example, I have a
full orch score with 14 sounds plus perc. Then I change strings to pizz, and
then violin I as solo violin, then trumpet muted. Now there are 18 instr even I revert these sounds back, and
the topmost instr (picc and fl) changes to string ensemble due to wrapping.
I hope that the initial instr amount is considered as basic midi instrument amount,  and the subsequent created sounds within a single track is treated as common program changes. This will make it convenient to play midi files by reassigning patches in software like Synthfont.
