[v2,01/11] reftable: consistently refer to `reftable_write_options` as `opts`

Series reftable: expose write options as config | expand

Commit Message

Throughout the reftable library the `reftable_write_options` are
sometimes referred to as `cfg` and sometimes as `opts`. Unify these to
consistently use `opts` to avoid confusion.

While at it, touch up the coding style a bit by removing unneeded braces
around one-line statements and newlines between variable declarations.

Passing struct by value is somewhat unusual.  As long as the
structure does not contain any pointer to something else, it is not
too bad as structure assignment would also work well, though.  Not a
fault of this patch, and this series is not a place to change
anything about it.

Nice attention to detail.
