Newer GCC warns us that the channel_map and volume in legacy entries are
accessed via pointers, and these might be unaligned as the legacy entry
is a packed structure. For this reason, we read out those values into
local variables before accessing them as pointers.
The warnings are:

HACKING:
In order to run pulseaudio from the build dir __OPTIMIZE__ should be
disabled (look at src/pulsecore/core-util.h::pa_run_from_build_tree()),
this can be done by passing "CFLAGS=-O0" to the configure script:
./autogen.sh
CFLAGS="-ggdb3 -O0" LDFLAGS="-ggdb3" ./configure
make
./src/pulseaudio -n -F src/default.pa -p $(pwd)/src/
