(pwdgrp::load): Call generic add_line function which will call correct parser.

* pwdgrp.h (etc): Move to path.h. (pwdgrp::max_lines): New field. (pwdgrp::curr_lines): New field. (pwdgrp::pwdgrp_buf): Ditto. (pwdgrp_buf_elem_size): Ditto. (pwdgrp_parse): Ditto. (pwdgrp::gets): Just declare here. (pwdgrp::load): Ditto. Just take one argument. (pwdgrp::load): Define overloaded function accepting passwd buf. (pwdgrp::load): Define overloaded function accepting group buf. * grp.cc: Use pwdgrp elements rather than standalone static variables throughout. (curr_lines): Eliminate. (max_lines): Ditto. (add_grp_line): Ditto. (parse_grp): Define as returning boolean. Accept void * arg and line count. Coerce first argument into __group32 buf reference. Increment curr_line as appropriate. (read_etc_group): Pass pwdgrp buffer to gr.load. * passwd.cc: Use pwdgrp elements rather than standalone static variables throughout. (curr_lines): Eliminate. (max_lines): Ditto. (add_grp_line): Ditto. (parse_passwd): Define as returning boolean. Accept void * arg and line count. Coerce first argument into passwd buf reference. Increment curr_line as appropriate. (read_etc_group): Pass pwdgrp buffer to pr.load. * path.cc (etc::fn): Extend buffer size to allow index by 1 rather than zero. (etc::last_modified): Ditto. (etc::change_possible): Ditto. Renamed from sawchange. Change to signed char since elements are now tri-state. (etc::init): Assume "handle" is 1 based rather than 0. (etc::test_file_change): New function. Sets change_possible based on file date comparison. (etc::dir_changed): Check file states immediately after changed_h is initialized to avoid a race. (etc::file_changed): Use test_file_change to detect if file needs to be updated. * path.h (etc): Move class here from pwdgrp.h. * uinfo.cc: Move etc:: functions to path.cc.
