Root cause fix for dock audio glitch

The 1-second periodic audio pop/click when streaming via MFi docks (Onkyo ND-S1) was caused by a 64KB memmove with interrupts disabled in iap_handlepkt(). At 54 MHz, this took ~1-5ms — enough to miss the 1ms USB SOF frame deadline, causing ISO IN audio dropouts.

Fix

  • Bounded memmove: only copy the remaining used bytes instead of the full 64KB buffer. For typical dock HID packets (~10 bytes), the IRQ-disabled window shrinks from ~1-5ms to <1µs.
  • Removed iap_hid_extract_buttons() workaround from v5.1-alpha.0, restoring full iAP stack processing during streaming. Dock controls now work through standard lingo handlers.
