Clean up old/dead code.
Merge branch 'develop' into logging
Extend the schema page title to make it clear where to go for the
column/index/projection stuff.
Add an example of using projections to return a subset of values from a
table.
Consolidate to a single free function for lists of log files.
Make the not-yet-supported comment read more naturally.
Add a more complex raw mode example, plus an example showing a projection
combined with raw mode.
It's bad style (IMNSHO), but declare the WT_ITEM locally to make it
clear the type we're using.

Update the list, remove non-existent files.
Add a new cell type, WT_CELL_KEY_PREFIX, that appears on row-store leaf
pages and has an associated prefix-compression byte.  Ref #600.
Emphasize schema-level cursors (table, colgroup, index) as normal.  Low-level cursors such as "file:" and "lsm:" are special cases.
