Names like
  - nm_settings_connection_get_autoconnect_retries
  - nm_settings_connection_set_autoconnect_retries
  - nm_settings_connection_reset_autoconnect_retries
are about the same thing, but they are cumbersome to grep
because they share not a common prefix.

Rename them from SUBJECT_VERB_OBJECT to SUBJECT_OBJECT_VERB,
which sounds odd in English, but seems preferred to me.
Now you can grep for "nm_settings_connection_autoconnect_retries_" to
get all accessors of the retry count, or "nm_settings_connection_autoconnect_"
to get all accessors related to autoconnect in general.
