c2r new array gives wrong result.

[rainwoodman]

it is due to line 953 in api-basic.c

complex_conjugate(conj_in, conj_out, ths->rnk_n, ths->local_ni);

This line overwrites the input with the output.
This wasn't caught by the test case due to pull request #3

These are the broken tests; seems to be all r2c.
