Instead it is part of Manager which is already itself a singleton
When the client requests termination of the daemon, the DBusManager instance
is not destructed, so we avoid using already freed memory

make Manager::(un)serialize static functions, they don't depend on the instance state
No need to check for the NULLity of _dbus anymore

Remove a useless argument to initConfigFile

use dlerror() correctly

remove a few messages

sflphone-common -> daemon
sflphone-client-gnome -> gnome
sflphone-client-kde -> kde
sflphone-plugins -> plugins

Move all the code in a single .h file

It calls strdup on its parameters internally.

decoder takes the size of encoded buffer and returns number of samples
encoder takes the maximum size of output buffer and returns compressed size
(it assumes we will encode only one frame at a time)

fix a use after free

Try to avoid confusion between size in bytes and number of samples
Use statically allocated buffers for decoders / encoders / filters / resamplers

We assume we won't be processing more than 20ms of audio mono at 44.1kHz

This reverts commit f0a7fe36.

That way we're guaranteed that it is safe to delete it after.

don't call methods on deleted objects!

Also the memory pool for the SDP must be deallocated after we've destroyed
the SDP.
