Remove macros

[juntuu]

Removed unused macros.

There are still some macros that are only used via token pasting, and thus appear unused when searching directly:

• \<type>##SIZE
• \<name>##values
• VA[12]##\<id>

Also removed ARGCHK*D macros and expanded & removed ARGCHK* macros; resolves #47, also part of #13.

I got quite a few uses removed, but some places needed the check.

I think some of the maros on my list are removed in this pull request https://github.com/codereport/jsource/issues/60 If you got all 10 or the remaining ones, we can close my issue.
