Stop exporting __pw_scan and __pw_initpwd as freebsd-private libc functions

Make pw_scan(3) more compatible with getpwent(3) et. al. when processing

data from /etc/passwd rather than /etc/master.passwd. The libc getpwent(3) and related functions automatically read master.passwd when run by root, or passwd when run by a non-root user. When run by non- root, getpwent() copes with the missing data by setting the corresponding fields in the passwd struct to known values (zeroes for numbers, or a pointer to an empty string for literals). When libutil's pw_scan(3) was used to parse a line without the root-accessible data, it was leaving garbage in the corresponding fields. These changes rename the static pw_init() function used by getpwent() and friends to __pw_initpwd(), and move it into pw_scan.c so that common init code can be shared between libc and libutil. pw_scan(3) now calls __pw_initpwd() before __pw_scan(), just like the getpwent() family does, so that reading an arbitrary passwd file in either format and parsing it with pw_scan(3) returns the same results as getpwent(3) would. This also adds a new pw_initpwd(3) function to libutil, so that code which creates passwd structs from scratch in some manner that doesn't involve pw_scan() can initialize the struct to the values expected by lots of existing code, which doesn't expect to encounter NULL pointers or garbage values in some fields.

This exposes ZFS user and group quotas via the normal

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.) Reviewed by: delphij, mav Approved by: mav Sponsored by: iXsystems Inc Differential Revision: https://reviews.freebsd.org/D15886

Use __SCCSID() for SCCS IDs.

- Define NO__SCCSID in CFLAGS to preserve existing behavior of omitting SCCS IDs by default. - While here, fix the $FreeBSD$ in pw_util.c to use __FBSDID.

humanize_number(3): fix math edge case in rounding large numbers

2017-12-28T22:57:34Z

Fix for remainder overflow, when in rare cases adding remainder to divider exceeded 1 and turned the total to 1000 in final formatting, taking up the space for the unit character. The fix continues the division of the original number if the above case happens -- added the appropriate check to the for loop performing the division. This lowers the value shown, to make it fit into the buffer space provided (1.0M for 4+1 character buffer, as used by ls). Add test case for the reported bug and extend test program to support providing buffer length (ls -lh uses 5, tests hard-coded 4).

lib: further adoption of SPDX licensing ID tags.

2017-11-26T02:00:33Z

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.

Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.
