* Speed up pw operations that edit /etc/group or /etc/passwdAlan Somers2016-11-181-0/+1
| | | | | | | | | | | | | | r285050 fixed a bug in pw that could lead to /etc/passwd or /etc/group corruption on power loss. However, it fixed it by opening those files with O_SYNC, which is very slow, especially on ZFS. This change replaces O_SYNC with appropriately placed fsync()s instead, which is much faster. Using a ZFS tmpdir, the time to run pw's kyua tests drops from 245s to 35s.

| | | | | | | | assignment of `l' in `gr_update' to the return value of snprintf. It claimed to have fixed the case where snprintf returned -1--in fact, it broke the entire routine. Not setting `l' here causes fileupdate() to invariably fail with EINVAL because it does its own check to assert that the parameter isn't -1.

| | | | | | | | | | | | instead of a boolean. This replicated through he front-end sub-functions relating to add, delete, modify entries in passwd & group files Errno is now preserved so output of errc()/warnc() will be less obfuscated by subsequent errors when reporting the problem. Add more intelligent error handling when attempting to modify/delete NIS entries with no corresponding local database entry. [MFC to stable in a couple of weeks to keep both in sync]
