Pierre Bourdon 9a404ca6d4 Ship by default a free DSP ROM that can handle most games with LLE 
At the end of July 2011, LM published a free DSP ROM that works with games
using the Zelda UCode. His ROM only has the code to handle UCode loading and a
few utility functions, the rest is missing. This includes the four large sound
mixing functions used by the AX UCode and the DROM containing coefficients used
for polyphase resampling in AX.

This is an improved, updated version of this ROM, which changes the following:

- We now have a free DROM that works for polyphase resampling by "emulating"
  linear interpolation. The coefficients contained in the DROM are normally a
  list of { c1, c2, c3, c4 } which are used to interpolate a sample value from
  four previous samples:
    out_sample = prev1 * c1 + prev2 * c2 + prev3 * c3 + prev4 * c4

  The coefficients are chosen depending on the fractional part of the current
  position (basically, our position between the previous and the next sample).
  We can use this fact to generate (c1, c2, c3, c4) for each possible
  fractional part so that:
    out_sample = prev3 * curr_pos + prev4 * (1 - curr_pos)

  Which is the formula for linear interpolation between prev3 and prev4. Linear
  interpolation is not as good as polyphase resampling but it still works very
  well and I couldn't really hear any difference between the two. If someone
  wants to generate real polyphase filter coefficients, they are welcome to
  submit a patch.

- The IROM now contains the 4 mixing functions used by the AX UCode: mix_add,
  mix_add_two, mix_add_ramp, mix_add_ramp_two. They are large, inlined
  functions (probably for performance reasons) in the official DSP IROM, our
  version prefers to use a loop. This *should* be more performant with our DSP
  JIT implementation, but I did not benchmark that.

Because the new DSP ROM is working just as well as the official ROM in 95% of
cases, it is now shipped by default with Dolphin and will be used with DSPLLE
if you don't have an official DSP ROM in User/GC. It will still display a panic
alert at every boot to notice you that you are using a non official DSP ROM
made by us, which is not perfect.

Games using the CARD, IPL or GBA UCodes are still broken. I don't know what
games this actually impacts, but this is a very small proportion compared to
what works.

Soren Jorvang 664cea45c7 Meta: 
Using Unix tools to operate on a tree containing filename with spaces in them
is really annoying, so rename the handful of instances where there were spaces.

Host.cpp has never been used.

Games tend to lookup the following directories that we don't yet have anything
to put in, so prepopulate them in Data/User/Wii:

title/00010001
title/00010002
title/00010003
title/00010004
title/00010005
title/00010006
title/00010007
meta
shared2/title
 
Set eol-style native on a number of text files which didn't already have it.

Goal is complete/near complete RE of DSP_UC_6A696CE7 (GC AX), and hopefully ROM.
From there, seeing the additional changes in other GC AX versions (there are only 4 others, with minor differences), should be "simple".
