Avery Pennarun ded14507b0 Rename vars{,_init}.py -> env{,_init}.py.
This fixes some pylint 'redefined builtins' warnings.  While I was
here, I fixed the others too by renaming a few local variables.

j,jobs= maximum number of jobs to build at once
d,debug print dependency checks as they happen
v,verbose print commands as they are read from .do files (variables intact)
x,xtrace print commands as they are executed (variables expanded)
k,keep-going keep going as long as possible even if some targets fail
shuffle randomize the build order to find dependency bugs
version print the current version and exit
redo-log options:
no-log don't capture error output, just let it flow straight to stderr
no-details only show 'redo' recursion trace (to see more later, use redo-log)
no-status don't display build summary line at the bottom of the screen
no-pretty don't pretty-print logs, show raw @@REDO output instead
no-color disable ANSI color; --color to force enable (default: auto)
debug-locks print messages about file locking (useful for debugging)
debug-pids print process ids as part of log messages (useful for debugging)
