@brief Copies the state of this variant to another variant

@rst Copies the site, genotypes and alleles from this variant to another. Note that the other variant should be uninitialised as this method does not free any memory that the other variant owns. After copying other is frozen and this restricts it from being further decoded at any site. self remains unchanged. @endrst

@param self A pointer to an initialised and decoded tsk_variant_t object. @param other A pointer to an uninitialised tsk_variant_t object. @return Return 0 on success or a negative value on failure.
