The more standard 'source' command provides identical functionality to
the autoscr command.

Environment variable names/values on the MVBC_P, MVBML7, kmeter1,
mgcoge, and km8xx boards are updated to no longer refernce 'autoscr'.

The 'autoscript' and 'autoscript_uname' environment variables are
also removed.

The individual i2c commands imd, imm, inm, imw, icrc32, iprobe, iloop,
and isdram are no longer available so all references to them have been
updated to the new form of "i2c <cmd>".
