Comment:

 I get an error when logging into GH right now, so the review comes inline
 here:

 I can see most of these things comes from code movement, but I think we
 can clean them up in follow up patches while this refactoring is
 happening:

 On line 133 in `microdesc_parse.c`: There is a typo in the comment: witll
 should be will.
 On line 143 in `microdesc_parse.c`: Minor detail, but `copy_body` could
 become a bool here.
 On line 147 in `microdesc_parse.c`: `no_onion_key` can be promoted to a
 bool.
 On line 319 in `microdesc_parse.c`: `body_not_found` can also be turned
 into a bool.

 Otherwise I think the refactoring looks good.
