lsm303: rename to lsm303dlh

There are a variety of LSM303 devices out there with various
incompatibilities and differing capabilities.  The current lsm303
driver in UPM only supports the LSM303DLH variant, so it has been
renamed to lsm303dlh to avoid confusion and to make it clear which
variant is actually supported.

All examples and source files have been renamed, including header
files.  In addition, the class name, LSM303, has been renamed to
LSM303DLH.  No other functionality or behavior has been changed.
