Changes to the pkgsrc infrastructure and notes:

- Note that Firefox, Thunderbird and likely other packages with
  difficult dependencies do not build on NetBSD 8 and other systems
  with non-recent compilers.  Users who wish to run these programs are
  advised to update to NetBSD 9 or newer versions of other operating
  systems.

Instructions on using the binary package manager can be found at
https://pkgin.net, and pkgsrc itself can be retrieved from via CVS or
tar file, and also from a mirror at https://github.com/NetBSD/pkgsrc.
See https://www.netbsd.org/docs/pkgsrc/getting.html for instructions.
The branch name for the 2021Q1 branch is "pkgsrc-2021Q1".
