Martin Gräßlin 08ab2c424e [kwin_wayland] Split out Buffer and ShmPool into dedicated files
Moved from wayland_backend.[h|cpp] to buffer.[h|cpp] and
shm_pool.[h|cpp]. Buffer is slightly adjusted to have the ShmPool
passed in as a ctor argument and the ctor is private and friended with
ShmPool, so that it can only be constructed from ShmPool.
