For some sound hardware, changing the volume channel has little

This patch implements this feature. The new --fade-exponent receives
an argument to control the level of non-linearity. The default value
of zero results in old behavior: linear scaling.
For the implementation we need to compute (the inverse of) t ->

para_fade operates in one of several modes, but the command line

subcommand can be made local to that subcommand.

existing scripts. So it seems to be prudent to rename the executable

build: Create .dep files only during compilation.
It is unnecessary to run a dedicated command to create the dependency
files because:
* If the object file does not exist, we have to run the compiler
anyway, which creates the dependency on the fly.
* If the object file exists, the dependency file also exists, so
the build system notices if the object file needs to be rebuilt,
for example because an included header file was modified.
The only thing we must guarantee is that all included header files
exist. We do this by introducing an order-only dependency: all object
files depend on all .lsg.h files but we impose this specific ordering
without forcing the targets to be updated.

This approach runs into problems if header files are removed and the
now stale .d file depends on a file which no longer exists.
It is enough to let the .d file depend only on the corresponding
.c file. In case an included file changes or is removed, the .c
file changes as well, so we already know we must build the object
file and can update the .d file at the same time, without running
cc twice. The -MMD option which is added to the usual cc command
instructs the compiler to create both the .d and the .o file in one go.
When creating the .o and .d files simultaneously, we don't need a
sed command to prepend the directory containing the .lsg.h headers
as these files are prerequisites of the object file being created,

The filter structure is now stored in the user_data pointer provided

FILTER_ENUM macro and the corresponding enumeration constants.
The removal of the ->goo_help member of struct filter makes this
structure constant. Hence ->init() of struct filter can also go
away. We still can tell whether a filter is supported by checking
the user_data pointer: if it is NULL, the filter is unsupported. The
new filter_supported() helper in filter_common.c is provided for
convenience.
Parsing of the filter command line options is now performed
generically, and the ->parse_config() method is renamed to ->setup(),
an optional function which is supposed to perform semantic checks

->teardown() which replaces ->free_config().
The conversion of the individual filters is easy since most filters
have a simple syntax or take no arguments at all. The resample_filter,
however, needs a different way to copy the wav parameters from the
lopsub parse result to the wav parms structure. A suitable macro,
LLS_COPY_WAV_PARMS is added to check_wav.h for this purpose. The old
COPY_WAV_PARMS needs to stay until para_write, the only other user

the manual page of audioc is now generated with lopsubgen.
Since this is the first executable which is converted, the commit
introduces a fair amount of infrastructure which will also be used
by other executables. Specifically:
* Common command line options (--help, --detailed-help, --version,
--loglevel, --history_file, --complete) are stored in per-option
files below m4/lls/include. Each of these files is included from
audioc.suite.m4. To tell make which files audioc.suite depends on,
we use the line synchronization feature of m4 and a simple awk script
to create a .m4d file which contains these dependencies, similar to
the .d files which describe dependencies of .c and .h files. The new
m4_lls_deps make variable contains the set of .m4d files.
* A generic copyright section for the man page which refers to the
COPYRIGHT_YEAR macro, defined from the make variable in Makefile.real.
* The new make variable LOGLEVELS. We need to know the set of loglevels
in the suite files as well as in the C code, so the variable avoids
to duplicate this information.

Remove *.cmd and command_util.bash.
The four *.cmd files are no longer needed and can be removed,
along with the script which transformed these files into C code. The
directory for the generated files, $(build_dir)/cmdlist, can go away
as well.
With command_util.bash gone, the Makefile can also be cleaned up
considerably. In particular, the ugly TOUPPER make function can be
removed because it was only used by the command_util recipe. Moreover,
The dependencies for the *.command_list.* files are no longer needed.
Finally, the sed command which fixed up the dependencies in the *.d
files can be simplified.

play: Remove support for non-lopsub commands.
This cleans up play.c to get rid of struct pp_command, the array of
command handlers and the compatibility code for non-lopsub commands
in run_command() and com_help().
Also the FOR_EACH_COMMAND() macro to iterate over all non-lopsub
commands can go away and we no longer need to include the

Converting com_ff() is analogous to com_jmp() since both subcommands

play: Convert com_jmp() to lopsub.
The command handler needs to check that there is a single argument
which is an integer between 0 and 100. This check needs to be modified
to use the lopsub primitives rather than accessing the argument
vector directly.
Unfortunately we can not perform the conversion of the string argument
into an int value with lopsub since the given percentage is an unnamed
option rather than an argument of an option.
The patch also rewords the summary and the help text of the jmp
subcommand slightly to be more clear.

play: Convert com_next() to lopsub.
com_next() is also called from com_jmp(), where we needed to pass

from com_jmp().

play: Link against lopsub and convert com_help() to lopsub.
This introduces the play_cmd suite for the subcommands of para_play,
like play, pause, fg, bg, etc. The new suite contains only the
"help" subcommand so far. Other commands will be converted one by one
in subsequent patches.
We make use of the lopsub user_data feature to store a pointer to the
command handler in the lls_command structure generated by lopsubgen.
This pointer is initialized by the new EXPORT_PLAY_CMD_HANDLER macro
in play.c.
The suite has no supercommand, therefore lopsubgen adds a special
"unavailable" identifier to play.lsg.h. We must therefore provide a
dummy completer for the fake supercommand.
Until all subcommands are converted, the run_command() and com_help()
subcommand need to iterate over two command lists. Afterwards, this
compatibility code can be removed.

This is no longer needed as there are no more non-lopsub

function. Moreover, ->patterns of struct pattern_match_data is unused

Command handlers should not look at the argv[] vector directly
but only use the lopsub library functions to access the parsed
command line.
In fact, the only function which accesses the argv vector is
run_command(). Defining argc and argv as local variables in this
function allows to drop the two members from the command context
structure.

Enable partial matching for server commands.
The feature was deactivated in an earlier commit which converted the
lsatt command to lopsub. The problem was that "ls" would have been
interpreted as lsatt because lsatt was the only converted command
that started with ls.
Now that all server commands are converted, the lopsub library function
lls_lookup_subcmd() does the right thing, so this patch removes the
additional test for an exact match.

server: Convert com_ls() to lopsub.
This is the final server command to be converted to the lopsub API.
Besides the conversion to lopsub, the patch changes the semantics
of the ls command in two ways: The deprecated -p option is removed,
and the -F option is made the default so that full paths are printed
if -b is not given.
Regarding the conversion, the patch removes enum ls_flags which used to
contain the various flags of the ls command. This information can now
be extracted in the callback from the deserialized parse result. Also
write_score() is kind of pointless and is replaced by inlining it.
Note that make_status_items() is also affected by this patch because
it makes use of the infrastructure of the ls command. This function
is called from the event handler of the audio file table for events
of type AFSI_CHANGE and AFHI_CHANGE.
Since no more non-lopsub server commands are left after this patch,
several cleanups are possible. These are dealt with in subsequent
patches.

server: Convert blob commands to lopsub.
This converts all blob commands (ls, cat rm, mv) in one go to lopsub,
making the patch rather large.
The addblob commands are special in that we must pass not only the
blob name given at the command line to the callback but also the
blob data which was read from stdin. The command handler does not
serialize the parse result like most other commands do, but constructs
a query object containing name and data for the callback. Therefore
the command handler does not call send_lls_callback_request() but
send_callback_request(). We continue to follow this scheme.
blob.c contains a few macros which expand to a set of functions,
one for each type of bloc (mood, playlist, image, lyrics). These
macros have to be adjusted to take another argument because we need
the prefixes (e.g., lyr for lyrics) in both upper and lower case and
there is no preprocessor toupper().
