   The following functions are used to add strings to be printed and prompt
   strings to prompt for data.  The names are UI_{add,dup}_<function>_string
   and UI_{add,dup}_input_boolean.

   UI_{add,dup}_<function>_string have the following meanings:
        add     add a text or prompt string.  The pointers given to these
                functions are used verbatim, no copying is done.
        dup     make a copy of the text or prompt string, then add the copy
                to the collection of strings in the user interface.
        <function>
                The function is a name for the functionality that the given
                string shall be used for.  It can be one of:
                        input   use the string as data prompt.
                        verify  use the string as verification prompt.  This
                                is used to verify a previous input.
                        info    use the string for informational output.
                        error   use the string for error output.
   Honestly, there's currently no difference between info and error for the
   moment.

   UI_{add,dup}_input_boolean have the same semantics for "add" and "dup",
   and are typically used when one wants to prompt for a yes/no response.

   All of the functions in this group take a UI and a prompt string.
   The string input and verify addition functions also take a flag argument,
   a buffer for the result to end up with, a minimum input size and a maximum
   input size (the result buffer MUST be large enough to be able to contain
   the maximum number of characters).  Additionally, the verify addition
   functions takes another buffer to compare the result against.
   The boolean input functions take an action description string (which should
   be safe to ignore if the expected user action is obvious, for example with
   a dialog box with an OK button and a Cancel button), a string of acceptable
   characters to mean OK and to mean Cancel.  The two last strings are checked
   to make sure they don't have common characters.  Additionally, the same
   flag argument as for the string input is taken, as well as a result buffer.
   The result buffer is required to be at least one byte long.  Depending on
   the answer, the first character from the OK or the Cancel character strings
   will be stored in the first byte of the result buffer.  No NUL will be
   added, so the result is *not* a string.

   On success, the all return an index of the added information.  That index
   is useful when retrieving results with UI_get0_result(). */

/* ---------- For method writers ---------- */
/*-
   A method contains a number of functions that implement the low level
   of the User Interface.  The functions are:

        an opener       This function starts a session, maybe by opening
                        a channel to a tty, or by opening a window.
        a writer        This function is called to write a given string,
                        maybe to the tty, maybe as a field label in a
                        window.
        a flusher       This function is called to flush everything that
                        has been output so far.  It can be used to actually
                        display a dialog box after it has been built.
        a reader        This function is called to read a given prompt,
                        maybe from the tty, maybe from a field in a
                        window.  Note that it's called with all string
                        structures, not only the prompt ones, so it must
                        check such things itself.
        a closer        This function closes the session, maybe by closing
                        the channel to the tty, or closing the window.

   All these functions are expected to return:

        0       on error.
        1       on success.
        -1      on out-of-band events, for example if some prompting has
                been canceled (by pressing Ctrl-C, for example).  This is
                only checked when returned by the flusher or the reader.

   The way this is used, the opener is first called, then the writer for all
   strings, then the flusher, then the reader for all strings and finally the
   closer.  Note that if you want to prompt from a terminal or other command
   line interface, the best is to have the reader also write the prompts
   instead of having the writer do it.  If you want to prompt from a dialog
   box, the writer can be used to build up the contents of the box, and the
   flusher to actually display the box and run the event loop until all data
   has been given, after which the reader only grabs the given data and puts
   them back into the UI strings.

   All method functions take a UI as argument.  Additionally, the writer and
   the reader take a UI_STRING.

The X509_STORE holds the tables etc for verification stuff.
A X509_STORE_CTX is used while validating a single certificate.
The X509_STORE has X509_LOOKUPs for looking up certs.
The X509_STORE then calls a function to actually verify the
certificate chain.
