Add linker version script to hide non-ABI stable symbols in the client

Browse source 
libraries. While this helps defining a more streamlined ABI, this also requires
linking a lot of additional symbols into some PA client utilities which until
now made use of the non-ABI stable symbols in libpulse. To minimize the effect
on there size a bit, strip unused symbols by linking with -ffunction-sections
-fdata-sections -Wl,--gc-sections
