dyndbg: cleanup auto vars in dynamic_debug_init
rework var-names for clarity, regularity
rename variables
- n to mod_sites - it counts sites-per-module
- entries to i - display only
- iter_start to iter_mod_start - marks start of each module's subrange
- modct to mod_ct - stylistic
new iterator var:
- site - cursor parallel to iter
1st step towards 'demotion' of iter->site, for removal later
treat vars as iters:
- drop init at top
init just above for-loop, in a textual block
