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.
- Enable upstream's hardened build mode.
