Kp 7fdce88558 Add parentheses around target of simple casts 
C casts do not require parentheses.  C++ casts require grouping around
the target.  Prepare for conversion to C++ casts by adding otherwise
unnecessary parentheses around the target of simple C casts.

This pass does not attempt to process expressions that involve
any subexpression that can nest arbitrarily, such as parentheses or
brackets.  It also works only on commonly used standard types.

Kp 568f165c28 Shrink sincos_table 
For all valid i, sincos_table[i] == sincos_table[i % 256].  Remove
elements [256:] and modify callers to truncate the index.

Kp a918692a23 Preprocess out EDITOR-only vm_vec_ang_2_matrix 
Remove vm_vec_ang_2_matrix from non-EDITOR builds so that
sincos_2_matrix has only one caller, allowing compiler to implicitly
inline it.

Kp 5e4bd5c73f vm_vec_delta_ang: check for vm_vec_copy_normalize failure 
derhass reports that Raspbian g++-4.8.2 rejects vecmat.cpp for
-Wmaybe-uninitialized on t0, t1.  Fix it by adding code to return 0 if
vm_vec_copy_normalize leaves the temporary uninitialized.
