[Dev-luatex] buglet in pdftex/luatex

we just noticed two buglets with \pdfstartlink/\pdfendlink:
- \pdfstartlink nodes are printed as pdflink
- The saved nested level of \pdf*link is only a small_number (0..63),
  while cur_s is an integer. This doesn't work. :-)
  This also means that \pdf*link only work at the first 63 levels (or
  since we are in web2c, they work till level 127 (signed char)). And
  yes, we need this. :-)

Here are patches for both:
