better job of integrating config options from the app environment as
well as config file while we're at it.

1129241fe0 Only open a session/cursor when first needed. There is still a race 
between vnodes during startup, ideally wterl_conn would only be opened
once.

fab5877ff5 Mistakenly allowed a file rename from another branch here. Use "wterl" 
not just "wt" for the shared library name.

1d6dfee192 Cache sizing is critical for performance. This change guesses at a 
reasonable setting for the WiredTiger cache size at runtime.  This cache
is shared across all vnodes regarless of how many are active at any
given time.  The algorithm is: max(1GB, 1/3 (RAM - Beam RSS size)). We don't
enable direct_io on purpose and data will be double buffered in WiredTiger's
cache and the filesystem buffer cache.  This turns out to be faster than
direct I/O despite wasting a bit of RAM.

789c44b133 Change the config to use a lsm tree rather than btree for tables. 
Stop using direct_io as it forces operations to sync more often, slowing
things down, at the expense of double-buffering (this will use more RAM).

c6eac27ea7 Start with a more rational default configuration. (Before you ask... the 
answer is 'no').  So far there has been no effort to validate that these
settings are in fact the best for Riak/KV or CS data access patterns.  These
particular settings are, at best, an educated guess based on past experience,
the docs and reading about the benchmark the WiredTiger team published here:

86955b0aef modify enable-wterl to avoid adding wterl repeatedly 
Before modifying files to add wterl, check to make sure the addition hasn't
already been made. Also change to do a stagedevrel build instead of a
devrel build.

99b096caf3 check return value of wterl:session_create 
Versions of WiredTiger prior to 1.3.3 had trouble handling riak restarts,
returning errors from wterl:session_create that would prevent riak from
restarting if it was not cleanly shut down on the previous run. We
previously avoided checking the return value of wterl:session_create to
avoid this problem. WT 1.3.3 fixes this, so reinstate the check of the
wterl:session_create return value.

b2807e2c14 upgrade to WiredTiger version 1.3.0 
Since 1.3.0 folded the session sync function into the session checkpoint
function, the wterl:sync/(2,3) functions are now renamed
wterl:checkpoint/(1,2). See
http://source.wiredtiger.com/1.3.0/upgrading.html for details.
