lib / string_helpers: move documentation to c-file
The introduced function string_escape_mem() is a kind of opposite to string_unescape. We have several users of such functionality each of them created custom implementation. The series contains clean up of test suite, adding new call, and switching few users to use it via %*pE specifier. Test suite covers all of existing and most of potential use cases. This patch (of 11): The documentation of API belongs to c-file. This patch moves it accordingly. There is no functional change.

- * '\"' - double quote
- * '\\' - backslash

- * %UNESCAPE_ANY:
- * all previous together

- * Returns amount of characters processed to the destination buffer excluding

- * Caller must provide valid source and destination pointers. Be aware that
