Comment (by jinmei):

 trac2506 is ready for review.

 Notes for the reviewer:
 - the first two commits are to address the remaining issues in #2375
   as noted in http://bind10.isc.org/ticket/2506#comment:1
   They are not related to the subject of this task and can be reviewed
   separately.
 - The third commit (c6c7cde) is big, but it's essentially just
   renaming the token class and trivial adjustments due to that.
   I suggest reviewing this diff separately.
 - The rest of the diff is the main part of the task.  It's basically
   a straightforward port of BIND 9's isc_lex_getmastertoken().
   There are some design decisions that may not be obvious.  I tried to
   clarify these in the documentation, so it's probably better to read
   it first, then the code.

 No plan to add a changelog for this.
