type: Rename vector_3_t to intv3_t.

Naming of many vector types and matrix types are not clear enough.
For example, we have:
  vector_3_t, which is a vector of three int.
  vec3_t, which is a vector of three float.
  size4_t, which is a vector of four size_t.
  mat33_t, which is a 3x3 matrix of float.
  matrix_3x3_t, which is a 3x3 matrix of fixed point.
Besides, we have types like int8_t, uint16_t types.

To clearly distinguished types, the CL propose to,

For vector types, naming should be `$type + 'v' + $num + '_t'`:
  vector_3_t becomes intv3_t
  vec3_t becomes floatv3_t
  vector 4 of uint16_t becomes uint16v4_t (which doesn't exist yet)

For matrix types, naming should be `mat$N$N_` + $type + '_t', where $N is the
matrix size:
  matrix_3x3_t becomes mat33_fp_t  # fp: fixed point
  mat33_t becomes mat33_float_t
