This reverts commit 8379c6eb07.
Reason for revert:
tcs.result_len is not the same as strlen(dptr->name) + 1
since it gets filled with filename
Change-Id: I1264afc0a43ffe75adf1de00d27ab98e3adbca19
the tagcache counts the null terminator strlen however, does not
no matching entries makes for a terrible amount of disk searching
and a hang on devices without dircache to save them

Distinguish read locks from write locks to aid converting the
mutex to an MRSW lock at some point in the future. Everything
is a write lock for now and a mutex is still used, so there's
no change in behavior.

This was insanely slow for large playlists. Implement it as a
constant-time operation to avoid the O(N!) blowup, and add a
new "clear" command to the control file to avoid flooding it
with individual delete commands.

This is all but guaranteed to be broken since pdbox doesn't use
SHAREDBSS_ATTR or SHAREDDATA_ATTR, needed to share memory safely
with COP threads.
Judging by the codec performance comparison on the wiki, if the
iRiver H100 and H300 can run PDbox on one core, PP targets should
have no problem doing it - they are 2-4x faster even on codecs
that don't have multi-core optimizations.

Apparently a response is coming out of nowhere and tripping this
check. I can't be bothered to look into it; it would be better to
just update the ARC USB driver to the new control request API...

Fix deadlocks in the dircache scan thread caused by incorrect
lock ordering. Mutating operations need to stop the thread to
prevent it from accessing invalid data; this must always be
done before taking the playlist lock to avoid deadlocking the
scan thread.

This is not necessary. Volatile doesn't create a memory barrier
wrt. non-volatile accesses and there are no interrupts involved,
so there's no reason to use it here.

Display volume bars using a perceptual scale instead of the
linear dB scale. This makes adjusting volume with the bar a
lot more usable on touchscreen targets.

The perceived loudness change of a change in volume depends
on the listening volume: at high volumes a 1 dB increment is
noticeable, but at low volumes a larger increment is needed
to get a comparable change in loudness.
Perceptual volume adjustment accounts for this fact, and
divides the hardware volume range into a number of steps.
Each step changes the dB volume by a variable amount, with
most of the steps concentrated at higher volumes. This
makes it possible to sweep over the entire hardware volume
range quickly, without losing the ability to finely adjust
the volume at normal listening levels.
Use "Volume Adjustment Mode" in the system settings menu
to select perceptual volume mode. The number of steps used
is controlled by "Number of Volume Steps". (Number of steps
has no effect in direct adjustment mode.)
It's still possible to set a specific dB volume level from
the sound settings menu when perceptual volume is enabled,
and perceptual volume does not affect the volume displayed
by themes.

The newer players have some changed hardware, but most importantly
the line out now appears to be routed through the stereo switch
instead of being hardwired directly off the DAC.
Disable muting the headphone amp, enable switching the stereo switch,
and rename some of the GPIOs to be more generic since the DAC,
headphone amp, and stereo switch all appear to have changed.

dircache_search() can yield, which would lead to memory corruption
if the playlist dcfrefs buffer is moved at that point. Prevent this
from happening by storing the buflib handle and pinning the buffer
while scanning the dircache.

It seems connecting an iPod Video to a Mac triggers the null
request check, resulting in a panic. Ignoring the error with
a bare return "fixes" it and allows the iPod to connect. This
isn't ideal though, because it could silently introduce bugs
on other targets.
The likely cause of this is the host sending control requests
too fast, or a driver problem (the Video uses the ARC driver,
which is still on the legacy interface), with multiple requests
getting queued at once. Since the USB core expects to deal with
only one request at a time, the second response trips the check.
Try to handle this situation a bit more gracefully by detecting
overlapped requests and returning a STALL to the host when it
occurs. At this point the USB stack is able to safely handle a
new request.

It turns out removing DSP_INIT broke the codec ABI and caused
old codecs to crash; the loop and mdelay() was a red herring.

Apparently queue_send() silently falls back to queue_post()
if sending isn't enabled. Doesn't seem like a good idea, as
post and send are definitely *not* interchangeable!
The playlist code relies on queue_send()'s blocking behavior
to prevent the dircache thread from using potentially stale
pointers.

Commit 6bcd830490 ported an optimization to decode_subframe_fixed()
from FFmpeg (upstream commit 08965b22e2). This contains an out of
bounds read, which doesn't affect the decoder output, but makes ASAN
complain.
FFmpeg fixed the out of bounds read (upstream commit 0ec7b71de8) but
that appears to increase code size a lot.
Inlining the initialization of a, b, c, d into the switch produces
similar code as the non-bounds-checked version with only a handful
of instructions of overhead (checked on MIPS & ARM).

These are more efficient than separate pin/unpin calls because
pin count increment and decrement can be done cheaply when the
data pointer is known.
Secondly, pinned access can be made safe against preemption by
hardware interrupts or other CPU cores; buflib_get_data() can't.
This makes it more useful under different threading models and
for SMP targets; both of which are not particularly relevant to
Rockbox now, but might be in the future.
