[Mesa-dev] [RFC 0/2] Alternate default config mechanism

[Sumit Semwal]

Mesa uses libexpat for many configuration parsing needs; however some
userspaces like Android may not want to use libexpat for various reasons -
eg some might restrict reading of any config xml files from filesystems.

This patchset proposes a simple lookup mechanism for the default values
as per current core mesa, keeping the same mesa-internal API as existing
xmlconfig.c.

Note:
This RFC doesn't change mesa drivers that directly use libexpat API - vc4
and intel gen decoder. If these drivers need Android to be enabled for
them, I request help from the experts there.

For building and testing this on current AOSP/master, I have two hack patches
- one provides empty dummy declarations for the XML* API in use in
gen_decoder, while the other disables vc4 decoder functionality. These can be
found at [1].

These have been built and boot-tested to UI on dragonboard.
