Erik Faye-Lund 4d066836e3 docs: convert articles to reructuredtext
This uses the previously added scripts to convert the documentation to
reStructuredText, which is both easier to read offline, and can be used
to generate modern HTML for online documentation.

No modification to the generated results have been done.

Mesa 18.0.0 Release Notes / March 27 2018
=========================================
Mesa 18.0.0 is a new development release. People who are concerned with
stability and reliability should stick with a previous release or wait
for Mesa 18.0.1.
Mesa 18.0.0 implements the OpenGL 4.5 API, but the version reported by
glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being
used. Some drivers don't support all the features required in OpenGL
4.5. OpenGL 4.5 is **only** available if requested at context creation
because compatibility contexts are not supported.

New features
------------
Note: some of the new features are only available with certain drivers.
- Disk shader cache support for i965 when MESA_GLSL_CACHE_DISABLE
environment variable is set to "0" or "false"
- GL_ARB_shader_atomic_counters and GL_ARB_shader_atomic_counter_ops on
r600/evergreen+
- GL_ARB_shader_image_load_store and GL_ARB_shader_image_size on
r600/evergreen+

the 18.0 release, 0 formats continue to be supported in compatibility
profiles.)
