[sql] Import reference version of SQLite 3.8.7.4.

[sql] Import reference version of SQLite 3.8.7.4.

Import the source for 3.8.7.4 per README.chromium.  This does not modify
the build in any way, it is being landed before being enabled to keep
the latter review focussed.

I'm TBR'ing this, because it's just importing new src to the side of stuff
that's part of the build.  I think it will make the switch CL easier to grok.

I've been debating the 3.8.8.x series, but in the end I decided I was too
nervous about it.  It's been so long, I'd rather get a stabilized update in
place first, then it should be easier to opportunistically pull a new SQLite. 
Especially if we can whittle down the patches.

Hold back encoding change which is messing up patch.

AFAICT from the logs, the failure is actually succeeding?  Third time is the
charm?
