Subject: [PATCH] lib/mingle: move ink.c into C++

lib/mingle already has a C++ source, requiring it to link against the C++
standard library. There is no advantage to keeping some of its sources in C.

This does nothing fancy, just rename the existing file. All contained code looks
compatible across C and C++. Future commits will refactor this to more modern
C++ style.

Gitlab: #2154
