Subject: Set package configuration options
Forwarded: not-needed

Configure Abseil for Debian.

  - Set the SONAME appropriately.

  - To minimize the possibility of future ABI breakage, treat absl::any,
    absl::optional, absl::string_view, and absl::variant as their own types
    (rather than aliases for the std:: versions), and compile everything in an
    inline namespace.
