8d2dbd281f pw useradd: Validate the user name before creating the entry
Previouly it was possible to create users with spaces in the name with:
pw useradd -u 1234 -g 1234 -n 'test user'

The "-g 1234" is relevant, without it the name was already rejected
as expected:

[fk@test ~]$ sudo pw useradd -u 1234 -n 'test user'
pw: invalid character ` ' at position 4 in userid/group name

Bug unintentionally found with a salt config without explicit name entry:

test user:
  user.present:
    - uid: 1234
    - gid: 1234
    - fullname: Test user
    - shell: /usr/local/bin/bash
    - home: /home/test
    - groups:
      - wheel
      - salt

"Luckily" salt modules rarely bother with input validation either ...

3dc869c257 pw usermod: Properly deal with empty secondary group lists (-G '')
"pw usermod someuser -G ''" is supposed make sure that someuser
doesn't have any secondary group memberships.

Previouly it was a nop because split_groups() only intitialised
"groups" if at least one group was specified. As a result the
existing secondary group memberships were kept.

7c46e6ef06 pw should sanitize the argument of -w.
Otherwise, it will silently disable the login for the selected account if
the argument is unrecognizable.

8ab28c4e4b pw_checkname since the beginning if too strict on GECOS field,
relax it a bit so gecos can be used to store multibytes data.

This was unseen before FreeBSD 10.2 as this validation function was motly unused
since FreeBSD 10.2 the usage of this function has been generalized to improve
validation.

069cc8a45f In pw_userlock, set 'name' to NULL when we encounter an all number string
because it is also used as an indicator of whether a name or an UID is
being used and we may have undefined results as 'name' may contain
uninitialized stack contents.

d2d022b9fd Rewrite parsing subcommands arguments of pw(8)
Now each subcommands checks its arguments in a dedicated functions.

This helps improving input validation, code readability/maintainability
While here:
- Add a -y option to pw userdel/usermod so it can maintain NIS servers if
  nispasswd is not defined in pw.conf(5)
- Allow pw -r <rootdir> to remove directory with userdel -r
- Fix bug when renaming a user which was not renaming the user name it groups
  it is a member of.
- Only parse pw.conf(5) when needed.

bbdee3ebde Reject usermod and userdel if the user concerned is not on the user database
supposed to be manipulated

This prevent pw usermod creating a new local user when requesting to usermod on
a username is defined in LDAP.

This issue only happens when modifying the local user database (not inpacting
commands when -V or -R are used).
