In short, the display fading back in after a pause resuming interferes
with the audio codec, causing BadThings(tm) that cannot be recovered from
This really is just avoiding a known trigger; there's no guarantee this
condition won't occur under random circumstances during normal use,
and there's no good way to work around this from within rockbox.
I suspect the underlying problem is that both the display control and
codec control share an i2c bus, but the kernel drivers implementing them
isn't using proper linux bus access/locking.

This also modifies the configuration file to include macros
defined in the H100 / H120 implementation.

* Enabled MULTIDRIVE and ROOTFS_HOTPLUG for full hotswap!
(Requires updated bootloader/integration!)
Change-Id: I7dad1f8d375e087c36fce37bec3e9184602ede50
* Cannot turn off the LCD directly (have to rely on backlight)
* Only insmod/rmmod the usb gadget modules if state changes
Change-Id: I9ea90177d496cd035ada93e04a93a7c6f2e84706
* Specify exported USB VID/PID in target config header
* Don't fail if the sd filesystem has already been remounted
(ie due to platform hotplug)

(we were trying to foward-declare functions from within static
initializer context. GCC no longer accepts this)

* Track mute state, only call hw if actual change is needed
* Don't unmute in audiohw_postinit()
* sample rate tracking fixes
* erosq: Don't start up muted
Change-Id: I004f787a4b7ea73c16b6ec9818ec29a12c89f46b
* If AUDIOHW_MUTE_ON_PAUSE, no meaningful change
* Unconditionally unmute on playback start
* xduoox3ii: Mute on sample rate change
* rocker/xduoo: Stay muted after startup
This avoids the nasty "pop" on startup, without doing
the full mute-on-pause stuff that causes unacceptable
dropouts on the X3ii.

* HOME_DIR is now either "/" or special "<HOME>"
* target-specific "home dir path" is defined solely by PIVOT_ROOT
* PIVOT_ROOT path is now defined in toplevel config files
* Make Samsung YP-R0/R1 and SONY_NWZ use PIVOT_ROOT too
* Do not prepend PIVOT_ROOT path if the path already has it!
* Do not play these games for __PCTOOL__ builds

The Q and K have a slightly different case, but the hardware under the
shell is completely identical.
These models are rebadged versions:
* Hifiwalker H2 (== Q)
* AGPTek H3 (== K)
* Surfans F20 (== K)
Other notes:
* Significant improvements in the shared Hiby-platform launcher/loader
* SD card can theoretically be hot-swapped now
* Support external USB mass storage!
* Some consolidation of Hiby-platform targets
* Some consolidation of plugin keymaps
Todo/known issues:
* Keymaps need to be gone over properly
* Convert to HAVE_SCROLLWHEEL?

It doesn't work properly and interferes with the power button in the keymap.
Rework WPS keymap a bit to make single-tap power emulate lock.

Note: PCM mix buffer sizes are _way_ too small for these high bitrates
(We really need to make the mixer stuff use dynamic buffer sizes based
on the bitrate. Maybe pre-allocate a max size based on upper bitrate limit,
but use only part of it at lower bitrates? So we can have sane latency..)

* xduoo x3ii/x20: Better line out support
* less granular volume settings (too many steps before)
* Better handling of swiching sample rates
* Log actual sample rate in debug menu

Additional integration [re]work by myself

* SAMPR_CAPS_ALL -> SAMPR_CAPS_ALL_48/96/192
* All targets claiming SAMPR_CAPS_ALL now get appropriate subset
* No need to explicitly define HAVE_PLAY_FREQ
* Rates that are a multiple of 44 or 48KHz can be used for playback
Inspired by a patch by Roman Stolyarov, but substantially rewritten by myself.

* DMA Bulk IN (ie our TX) results in sequential transfers 33-68% faster.
* DMA Bulk OUT (ie RX) is mostly stripped out due to complete brokenness.
* Interrupt and control endpoints remain PIO-driven.
Other improvements:
1) Use consistent endpoint references (no magic numbers)
2) Greatly enhanced logging
3) DMA support can be compiled out completely
4) Setting lockswitch will disable all DMA operations at runtime
5) Much more robust error checking and recovery

* Increase audio buffer size to better handle IRQ latency (256->2048)
* Ensure DMA engine is idle prior to starting transfers
* Set AIC to repeat last sample in case of underflows

Back off to 480MHz [max] clock, bus/mem clock of 120MHz.
576 is unstable on at least one unit, and 528 still glitches.
