Default shell environment enhancements: Skeleton user sh/ksh/ksh93/bash

Description and Justification:

This case proposes to introduce a set of enhancements for the default
shell environment in Solaris to provide a more user-friendly environment
for new users which are not yet familar with all the details in Unix and
to provide some help for adminstrators via introducing better system-wide
defaults and more configuration options.

The proposed changes  are:

- A change to "/etc/skel/local.profile".
  Currently the file contains (without lines beginning with '#'):
  -- snip --
  stty istrip
  PATH=/usr/bin:/usr/ucb:/etc:.
  export PATH
  -- snip --
  which is in the best case sub-optimal for a new user (e.g. the use of
  "/usr/ucb/" in a novice users default PATH may even be considered
  as harmfull).

  The case proposes that the current content should be removed and replaced
  with a comment that admins should edit "/etc/profile" (for
  sh/ksh/ksh93/bash/etc.) to change the PATH variable "globally" (e.g.
  machine-wide/site-wide) for all accounts (users can always edit
  "~/.profile" to override the settings but this should only be done
  optionally by _experienced_ users and _not_ by default for all new users).

  Any default settings of the default user login session environment should
  be done in "/etc/profile" or elsewhere but not in a per-user configuration
  file where it may be difficult for the adminstrator to redefine
  machine-/site-wide defaults later.

  Per-user files should strictly be used for user-specific customisations
  and if the user does not make any customisations the machine-/side-wide
  defaults should apply (e.g. the per-user files should be empty, however
  the empty files should still be delivered as documentation/hint/etc. how
  the system+user environment should be configured correctly - too many
  sites make a mess out of these little details).

- "/etc/skel/local.bashrc" as a new file to the system as a per-user
  version of "/etc/bash.bashrc", the content should only be a comment that
  admins should edit "/etc/bash.bashrc" instead to define
  machine-/site-wide settings.

- "/etc/skel/local.kshrc" as a new file to the system as a per-user version
  of "/etc/ksh.kshrc", the content should only be a comment that admins
  should edit "/etc/ksh.kshrc" instead to define machine-/site-wide
  settings.
