quatactl(2) mechanism. (Read-only at this point, however.)
In particular, this is to allow rpc.rquotad query quotas
for NFS mounts, allowing users to see their quotas on the
hosts using the datasets.
The changes specifically:
* Add new RPC entry points for querying quotas.
* Changes the library routines to allow non-UFS quotas.
* Changes rquotad to check for quotas on mounted filesystems,
rather than being limited to entries in /etc/fstab
* Lastly, adds a VFS entry-point for ZFS to query quotas.
Note that this makes one unavoidable behavioural change: if quotas
are enabled, then they can be queried, as opposed to the current
method of checking for quotas being specified in fstab. (With
ZFS, if there are user or group quotas, they're used, always.)

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

stat() call should detect that and fail.

The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.
This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.
quotactl(2) interface and inactive quotas by accessing the quota
files directly.
Update the edquota program to use this new interface as proof of
concept.
