parseStatus is an unused field within TidyDocImpl

[benkasminbullock]

The following field:

tidy-int.h:70:    int                 parseStatus;

is not used anywhere else within the library, and is purely an internal variable (part of TidyDocImpl, non-user visible type).

@benkasminbullock yes, it appears it is unused at this time... do not have time right now to go back in history to find where and when it was used, if ever...

But will leave it there as a sort of spare int variable in the main (opaque to users) structure. There have been times in development that I have wanted another flag in the internal doc, and will try to remember this next time that comes up... thanks...

That is I do not think this 4-byte allocation save is important at this time, so closing this, but thanks for pointing it out.

The reason to delete this is to make the source code easier for other people to read, not to save four bytes.
