    Added top-level form errors to complement specific ones (Bug #1262483)

    Pieforms now adds a global error message if there are any validation errors
    in a form, in addition to the messages beside each element. This is
    modified from the existing jserrormessage

Okay, the problem here is that Jono's code change doesn't support an obscure Pieforms feature that lets a form have multiple submit buttons, each of which gets its own submit function.

If you create a form with multiple submit buttons, and you create a function called {$formname}_submit_{$buttonname}(), then that function will be called by pieforms if the user clicks that button. This is used on exactly two forms: The profile picture picker, and the admin/users/suspended.php form for unsuspended, unexpiring, or deleting a user.

Notably, neither of these forms has a {$formname}_submit() method. And the way Pieforms is written, it's supposed to return after hitting that _submit() function, and if it doesn't return, it gets to the point where it displays this error message.

So probably the solution here, is that if it goes to a button submit function, it Pieforms should return.

An additional wrinkle in the problem is that those button-level submit callback functions are supposed to redirect() instead of returning, and the profile picture one was not redirecting, when you chose the default profile pic.

Prevent global form error from incorrectly showing up on forms with button-submit functions

Bug 1311940: There's an obscure pieforms feature where a form can have multiple submit
buttons, and each submit button can have its own submit callback function named
{formname}_submit_{buttonname}. These functions are supposed to redirect at the end.
If they don't, due to a bug in the implementation of the global form message we currently show
an error message at the top of the form saying there was something wrong with the user's
submission. Instead, we should just let the form go through, and log a debug message for
the devs.

No need to show a different message when setting profile icon to the default

Bug 1311940: Also, a pieform button-level submit function is meant to redirect
at the end every time. And this one was not.
