If bug 959058 sticks in the tree to release, remove the GB2312 and GBK decoders that became dead code.

When fixing this, also remove the strings gbk, gbk.key and gb18030 from charsetMenu.properties.

Whole push reverted due to the OS X bustage in: https://tbpl.mozilla.org/?tree=Mozilla-Inbound&rev=932a92a16c29&jobname=osx.*debug remote: https://hg.mozilla.org/integration/mozilla-inbound/rev/c2d07802d0f4 remote: https://hg.mozilla.org/integration/mozilla-inbound/rev/81ef2b9b375b remote: https://hg.mozilla.org/integration/mozilla-inbound/rev/a30b95df07ef

Oops. I failed to update the gfx code for processing legacy Mac Chinese font names and running only linux64 builds on try didn't catch that. Here's an addendum to do that. https://tbpl.mozilla.org/?tree=Try&rev=a2c56adf562c Note that names in WAP code and nsSearchService go through label-to-encoding handling, so it's not critical to update those, and those have more no-longer-canonical names around than just GB2312. I'll file bugs to update those.
