TTY/Serial fixes for 7.3-rc6

Here are some small tty/serial driver fixes for 7.3-rc6.  Nothing major
here, just lots of small fixes for reported issues, some of them very
long-standing:
  - tty hangup fixes that have been there since the BKL days and kept
    tripping people up over time.
  - vt selection bugfix
  - other vt bugfixes (memory leaks and screen update fixes)
  - n_gsm bugfix
  - qcom-geni serial driver bugfix
  - 8250 serial driver bugfixes
  - other tiny serial driver fixes

All of these have been in linux-next, the last few only a few days but
testing here seems solid (this pull request was generated on that tree)
