This allow to use palette on the stack instead of always
allocating them.

Corentin Chary e31e3694af vnc: palette: use a pool to reduce memory allocations 
We now that the palette will never have more than 256
elements. Let's use a pool to reduce malloc calls.

Corentin Chary 5136a05269 vnc: tight: stop using qdict for palette stuff 
Profiling with callgrind seems to show that a lot of time is spent
in the palette code (mostly due to memory allocation and qdict to int
conversion).

This patch adds a VncPalette implementation. The palette is stored
in a hash table, like qdict, but which does way less memory allocations,
and doesn't suffer from the QObject overhead.
