Tanay Abhra 6ea358f784 ll-merge.c: refactor read_merge_config() to use git_config_string() ...

There is one slight behavior change, previously "merge.default"
silently ignored a NULL value and didn't raise any error. But,
in the same function, all other values raise an error on a NULL
value. So to conform with other call sites in Git, a NULL value
for "merge.default" raises an error.

The the new config-set API is not very useful here, because much of
the function is dedicated to processing "merge.<name>.variable",
which the new API does not handle well.  If it were for variables
like, "merge.summary", "merge.tool", and "merge.verbosity", we could
use the new API.
