Previously the file handle for the newly created default config was
being closed and thrown away as opposed to returned to the caller to
finish setting up config for the rest of the process. This patch changes
to return a handle to the newly created config so setup can happen as
normal. This fixes a bug where Delve can crash on first run when a
config is not present on the system.
Fixes#1129
Adds a configuration option (show-location-expr) that when activated
will cause the whatis command to also print the DWARF location
expression for a variable.
