+ * string_unescape - unquote characters in the given string
+ * @src: source buffer (escaped)
+ * @dst: destination buffer (unescaped)
+ * @size: size of the destination buffer (0 to unlimit)
+ * @flags: combination of the flags (bitwise OR):
+ * %UNESCAPE_SPACE:
+ * '\f' - form feed
+ * '\n' - new line
+ * '\r' - carriage return
+ * '\t' - horizontal tab
+ * '\v' - vertical tab
+ * %UNESCAPE_OCTAL:
+ * '\NNN' - byte with octal value NNN (1 to 3 digits)
+ * %UNESCAPE_HEX:
+ * '\xHH' - byte with hexadecimal value HH (1 to 2 digits)
+ * %UNESCAPE_SPECIAL:
+ * '\"' - double quote
+ * '\\' - backslash
+ * '\a' - alert (BEL)
+ * '\e' - escape
+ * %UNESCAPE_ANY:
+ * all previous together
+ *
+ * Description:
+ * The function unquotes characters in the given string.
+ *
+ * Because the size of the output will be the same as or less than the size of
+ * the input, the transformation may be performed in place.
+ *
+ * Caller must provide valid source and destination pointers. Be aware that
+ * destination buffer will always be NULL-terminated. Source string must be
+ * NULL-terminated as well.
+ *
+ * Return:
+ * The amount of the characters processed to the destination buffer excluding
+ * trailing '\0' is returned.
