Get shared link working again.

Get shared link working again.

1) The spell checker works, but it was still in temp_scaffolding_stubs.
This meant different files had a different view of the class, causing
memory corruption on startup.  (Valgrind caught this.  We need a Valgrind
builder!)
2) The net library provides gtest-related bits and must depend on gtest.

This is the change I did earlier to make the shared build work.  It also fixes
some memory corruption that the shared build was tickling.  We should check in
mmoss's larger change, then I can redo mine on top of it.

CC'ing shess since he volunteered to fix the mac build, which is blocking this
change.

Doesn't apply cleanly to r10215, mostly LG though.

FYI, the other shared build changes are in.

Hunspell wasn't present at all on Mac, I have changes which seem to let it (and
your change) compile.  They're a little intrusive, and I'll be surprised if they
go in like this.  But I need to get out of the office for now.

Hi all,

I've uploaded a new patch that works around the mac problem.
