Thomas Martitz c46f9be10a talk: Smarter cache management for TALK_PARTIAL_LOAD.
Previously the clip cache of TALK_PARTIAL_LOAD reserved space N clips, each slot
was as big as the maximum sized clip which was necessary to replace clips
in-memory in MRU-style.

The cache management now uses buflib to allocate and free each clip, using the
clip's real size. This allows the clip cache to be much more compact, because
no space is wasted for the max. sized clip. This makes use of buflib's ability
to easily manage differently-sized memory chunks by moving them to make free
space.

As an example: for english.voice TALK_PARTIAL_LOAD allocated 288k in advance.
for just 64 clips. With this patch ~70 clips can be stored in a 100k buffer.
This, the memory usage is cut by 2/3 and almost optimal (there's still the
buflib per-alloc cookie overhead).

As a result the TALK_PARTIAL_LOAD buffer is restricted to 100k which still
allows for more clips than previously, on average.

Build Your Own Rockbox

1. Clone 'rockbox' from git (or extract a downloaded archive).

   $ git clone git://git.rockbox.org/rockbox

     or

   $ tar xjf rockbox.tar.bz2

2. Create a build directory, preferably in the same directory as the firmware/
   and apps/ directories. This is where all generated files will be written.

   $ cd rockbox
   $ mkdir build
   $ cd build

3. Make sure you have sh/arm/m68k-elf-gcc and siblings in the PATH. Make sure
   that you have 'perl' in your PATH too. Your gcc cross compiler needs to be
   a particular version depending on what player you are compiling for. These
   can be acquired with the rockboxdev.sh script in the /tools/ folder of the
   source, or will have been included if you've installed one of the
   toolchains or development environments provided at http://www.rockbox.org/

   $ which sh-elf-gcc
   $ which perl

4. In your build directory, run the 'tools/configure' script and enter what
   target you want to build for and if you want a debug version or not (and a
   few more questions). It'll prompt you. The debug version is for making a
   gdb version out of it. It is only useful if you run gdb towards your target
   Archos.

   $ ../tools/configure

5. *ploink*. Now you have got a Makefile generated for you.

6. Run 'make' and soon the necessary pieces from the firmware and the apps
   directories have been compiled, linked and scrambled for you.

   $ make
   $ make zip

7. unzip the rockbox.zip on your music player, reboot it and
   *smile*.

If you want to build for more than one target, just create several build
directories and create a setup for each target:

   $ mkdir build-fmrecorder
   $ cd build-fmrecorder
   $ ../tools/configure

   $ mkdir build-player
   $ cd build-player
   $ ../tools/configure
