databricks() driver auto-detection now recognizes the Windows driver
name Databricks ODBC Driver.

databricks() now sets DefaultStringColumnLength to 65535 by default.
The driver reports STRING columns as VARCHAR(DefaultStringColumnLength)
and silently truncates longer values; its own default of 255 caused string
data to be cut off after roughly 1000 characters. Pass
defaultStringColumnLength to dbConnect() to override (#1023).

Update vendored cctz to current upstream, including local build compatibility
fixes retained for R package and Windows builds.

Numeric connection string arguments no longer fall back to scientific
notation in build_connection_string(), which avoids malformed driver
attributes such as DefaultStringColumnLength (#934).
