WT-2381: dump utility discards table config

Rework the dump utility and the dump library support. Previously, the
metadata cursor returned a full set of WT_SESSION.create configuration
values, basically, the requested configuration values plus the default
values, where the requested configuration values overrode the default
configuration values. This doesn't work because dump takes a few
configuration strings and collapses them into a single string, and the
default configuration values start overriding real configurtion values.
Change the metadata cursor to return only the requested configuration
values instead, and change dump to add in the default values when it's
collapsing the strings into a single string.

Add a function __wt_schema_create_final; it takes a set of configuration
strings, adds in the default WT_SESSION.create configuration values, and
collapses them into a single string.

Add a function __wt_config_strip_and_collapse; it behaves similarly to
__wt_config_collapse, except it doesn't add in the default strings.

Fix bugs where we weren't copying returned metadata strings into local
memory.

Fix bugs where we weren't correctly parsing the URIs in the metadata
file.
