Import SQLite 3.10.2.

Ran through the import script in third_party/sqlite/README.Chromium,
including the SQLite test suite.  No new errors observed.

SQLite changes are at http://www.sqlite.org/changes.html , Chromium
previously used 3.8.7.4.

All patches were applied and the results reviewed to make sure
backported patches were safe to remove, and retained patches were still
covering what was necessary.

Keep fts4 disabled, and also the new fts3 virtual table and unicode61
tokenizer.  Once enabled, these are very hard to disable, and there
doesn't seem to be any pressure to enable them.  Set
SQLITE_DEFAULT_PCACHE_INITSZ to 0 so SQLite does not preallocate 100
pages to pcache (both so Chromium can manage memory, also because our
code disables shared pcache).  Other SQLITE_* flags were reviewed for
applicability, none looked essential.
