Enable outputting equalized symbols that are not exactly constellation
symbols. This is useful for OFDM soft decoding/demodulation (e.g.
optimal turbo or LDPC decoding).
For compatibility, this new behaviour has to be enabled by setting the
new option "enable_soft_output" to true (false by default).

Both of these defects are for the second parameter of the `constellation`
class' `map_to_points` function that accepts a pointer to an array of
`gr_complex` values. In both of these defects, a class is calling this function
and passing the address of a single `gr_complex` value in place of an array
pointer. The only reason this isn't exploding with SEGFAULTs is because both of
these functions happen to use the default constructor of `constellation`, which
sets the loop limit in `map_to_points` to `1`. It's generally a dangerous
design, but changing the function prototype seems heavy heanded, and adding
additional conditionals will end up affecting the fast-path. For now, I am just
documenting this oddity in the code.
