Full API convergence. Api is back in LSL_Api.cs and OSSL_Api.cs.

The binaries are still different, but that is only a small step away now.
The OSSLPrim has been removed. This commit will breal all scripts
using Prim.Scale(), etc, syntax. It was not secure and will have to
be brought back in another form.

+        a vector pointing along the X axis, first rotating it 3 degrees around the global Z axis, then rotating the resulting
+        vector 2 degrees around the global Y axis, and finally rotating that 1 degree around the global X axis.

+         * Experiment in SL to determine conventions:

+         *   llEuler2Rot(<0,PI,0>)=<0,1,0,0>
+         *   llEuler2Rot(<0,0,PI>)=<0,0,1,0>
+         *
+         * Important facts about Quaternions
+         *  - multiplication is non-commutative (a*b != b*a)
+         *  - http://en.wikipedia.org/wiki/Quaternion#Basis_multiplication
+         *
+         * Above SL experiment gives (c1,c2,c3,s1,s2,s3 as defined in our llEuler2Rot):
+         *   Qx = c1+i*s1
+         *   Qy = c2+j*s2;
+         *   Qz = c3+k*s3;
+         *
+         * Rotations applied in order (from above) Z, Y, X

+         * And with the results in SL.
+         *
+         * It's also possible to calculate llEuler2Rot by direct multiplication of

-        a vector pointing along the X axis, first rotating it 3 degrees around the global Z axis, then rotating the resulting

-         *
-         * Experiment in SL to determine conventions:

-         *   llEuler2Rot(<0,PI,0>)=<0,1,0,0>
-         *   llEuler2Rot(<0,0,PI>)=<0,0,1,0>
-         *
-         * Important facts about Quaternions
-         *  - multiplication is non-commutative (a*b != b*a)
-         *  - http://en.wikipedia.org/wiki/Quaternion#Basis_multiplication
-         *
-         * Above SL experiment gives (c1,c2,c3,s1,s2,s3 as defined in our llEuler2Rot):
-         *   Qx = c1+i*s1
-         *   Qy = c2+j*s2;
-         *   Qz = c3+k*s3;
