/**
* @brief safely quotes strings that might have double quotes in them.
*
* The devctl protocol relies on quoted strings having matching quotes.
* This routine quotes any internal quotes so the resulting string
* is safe to pass to snprintf to construct, for example pnp info strings.
* Strings are always terminated with a NUL, but may be truncated if longer
* than @p len bytes after quotes.
*
* @param dst Buffer to hold the string. Must be at least @p len bytes long
* @param src Original buffer.
* @param len Length of buffer pointed to by @dst, including trailing NUL
