[Buildroot] [pull request] Pull request for branch yem-package-create-user

[Yann E. MORIN <yann.morin.1998@free.fr>]

Hello All!

Here is a series that allows packages to create users.

Packages that install daemons may well want to run those daemons as
non-root users to avoid security issues. Currently, there are two users
of choice to run 'generic' daemons: root or daemon (although there are
a few dedicated users to run a few services: mail, sshd, ftp...).

This series builds upon both the package infrastrucutre to define the
user(s) a package may want to create, and the filesystem infrastructure
to actually generate these users, and chown their ${HOME}s.

Documentation is updated accordingly.

Note: for now, users' passwords are md5-encrypted. Once the pending
change to introduce alternative password-encryption schemes is applied,
we can use that to encode users' passwords, too.

As a proof of concept, the package tvheadend has been updated to use
a dedicated user to run its daemon as (call me stubborn! ;-] ).
