glx: Refactor the configure options for glx implementation choice (v3)
Instead of cascading support for various different implementations of
GLX, all three options are now specified through the --enable-glx
option:
--enable-glx=dri : Enable the DRI-based GLX
--enable-glx=xlib : Enable the classic Xlib-based GLX
--enable-glx=gallium-xlib : Enable the gallium Xlib-based GLX
--enable-glx[=yes] : Defaults to dri if DRI is enabled, else
gallium-xlib if gallium is enabled, else
xlib
This removes the --enable-xlib-glx option and fixes a bug in which both
the classic xlib-glx and gallium xlib-glx implementations were getting
built causing different versioned and conflicting libGL libraries to be
installed.
v2: Changes from various review feedback from Emil:
a) Fixed typos
b) Corrected help docs for new option
c) Added appropriate a-b and r-b tags in commit msg
d) Fixed various GLX related dependency checks.
v3: Rebased to current master and added changelog in commit msg
