Update Ceres to latest upstream version 2.1.0temp-ceres_update

This release deprecated the Parameterization API and the new Manifolds
API is to be used instead. This is what was done in the Libmv as part
of this change.

Additionally, remove the bundling scripts. Nowadays those are only
leading to a duplicated work to maintain.

-// Default (empty) configuration options for Ceres.
+// Configuration options for Ceres.
 //
-// IMPORTANT: Most users of Ceres will not use this file, when
-//            compiling Ceres with CMake, CMake will configure a new
-//            config.h with the currently selected Ceres compile
-//            options in <BUILD_DIR>/config, which will be added to
-//            the include path for compilation, and installed with the
-//            public Ceres headers.  However, for some users of Ceres
-//            who compile without CMake (Android), this file ensures
-//            that Ceres will compile, with the user either specifying
-//            manually the Ceres compile options, or passing them
-//            directly through the compiler.
+// Do not edit this file, it was automatically configured by CMake when
+// Ceres was compiled with the relevant configuration for the machine
+// on which Ceres was compiled.
+//
+// Ceres Developers: All options should have the same name as their mapped
+//                   CMake options, in the preconfigured version of this file
+//                   all options should be enclosed in '@'.
