Evas gl_x11: Fix runtime switching of GL window configurations

Browse Source

Test case:
- Elementary Test
-- GLView
--- Direct rendering

Direct rendering would never happen in reality, because Evas GL
had to fallback. The reason being that DR requires the window
to have a depth buffer, but this depth buffer was no present
in the default config.

From elm, the solution is to set a special accel_preference,
for instance "gl:depth". But setting this value right before
calling elm_win_add() for the GLView test was already too late.
Indeed, evas_x would keep the default configurations and reuse
them no matter what was requested (ie. only RGB and RGBA would
work).

Solution:
Implement a slightly more complex cache based on a hash map instead
of just two static variables. Always request a new config if it's
not found in the current hash. Store that config, and reuse it for
the same config requests.

Tons of line changes because of the name changes and the whitespace
adjustments. Also some variables disappeared into the magic hash table.
