[PATCH 2/7] nfs-utils: Merge conf_get_str and conf_get_section

[Justin Mitchell <jumitche@redhat.com>]

conf_get_section() started as conf_get_str() with one extra search
parameter, subsequent patches have not maintained feature parity,
combine the code to make a single more generic function and just call
that differently where required.
