This is almost the opposite function to string_unescape(). Nevertheless it
handles \0 and could be used for any byte buffer.
The documentation is supplied together with the function prototype.
The test cases covers most of the scenarios and would be expanded later on.

+ * 3. The character is checked if it falls into the class given by @flags.

+ * character. Note that they actually can't go together, otherwise
+ * %ESCAPE_HEX will be ignored.
+ *
+ * Caller must provide valid source and destination pointers. Be aware that
+ * destination buffer will not be NULL-terminated, thus caller have to append
+ * it if needs.
+ *
+ * Return:
+ * The amount of the characters processed to the destination buffer, or
+ * %-ENOMEM if the size of buffer is not enough to put an escaped character is
+ * returned.
+ *
+ * Even in the case of error @dst pointer will be updated to point to the byte
+ * after the last processed character.

Instead of custom approach this allows to print escaped strings via recently
added kernel extension: %*pE.
