[Dev-luatex] keeping in sync with pdftex changes

11 Jan 2021

      pdftex will in texlive 2021 change  in two places

1. links where \pdfstartlink is in a different boxing level as
\pdfendlink are no longer a fatal error but gives only a warning:

x\hbox{\pdfstartlink
    attr {/Border[0 0 1]}
    user{
        /Subtype/Link%
        /A<<%
         /Type/Action%
         /S/URI%
         /URI(blkub)%
         >>%
        } Linktext}
\pdfendlink

\bye

pdfTeX warning: \pdfendlink ended up in different nesting level than
\pdfstartl
ink

2. There are two new primitives \pdfrunninglinkoff &
\pdfrunninglinkon which allow to interrupt a running link for
example in the header or footer. 

Would it be possible to get this changes into luatex too?
