libixion, py-libixion: Update to 0.18.1

Changelog:
0.81.1
* fixed a 32-bit Linux build issue as discovered on Debian, due to
  a clash on two 32-bit unsigned integer types being used with std::variant.

0.18.0
C++ API
* removed the formula_model_access interface from model_context, and
  switched to using model_context directly everywhere.
* revised formula_tokens_t type to remove use of std::unique_ptr for each
  formula_token instance. This should improve memory locality when iterating
  through an array of formula token values. A similar change has also been
  made to lexer_tokens_t and lexer_token types.

formula interpreter
* added the following 41 built-in functions:
    ABS
    AND

Log message:
*: Re-apply SunOS linker argument removals.

These are currently duplicated in mk/platform/SunOS.mk but the generic
removals will be removed soon in favour of per-package removals, due to
flags getting leaked into installed files.

Log message:
libixion: remove patch that was removed from distinfo during update

Log message:
{py-,}libixion: Update to 0.17.0

Changelog:
0.17.0:
C++ API
    set the baseline C++ version to 17.
    mdds has been internalized so that the public header no longer contains \ 
references to mdds. With this change, the users can use different API versions \ 
of mdds between the ixion build and run-time use.
    cleaned up public API to make use of std::string_view and std::variant where \ 
appropriate.
formula interpreter
    implemented built-in LEFT() function.
misc
    it is no longer required to set the size of void* at build time to ensure \ 
the binaries to be fully functional.
    fixed a bug where named expressions with names containing invalid characters \ 
were still allowed in.
