Change the Windows build to statically link the sync library.

Change the Windows build to statically link the sync library.

Update installer files so that they don't reference syncapi.dll. Add a 
reference to iphlpapi, and make it and pthreads lazy-loaded.

I still need to do additional testing (I want to single-step through the
initialization code, and run the two-client sync integration tests), but this
seems to be working so far.

More info:

This adds 681984 bytes to a release chrome.dll (while eliminating syncapi.dll,
which was about four times the size).

Other tests I intend:
 - Verify that pthreads is indeed lazily-loaded.
 - startup perf tests
