Because /etc/profile (and ~/.profile) are read by login shells only,
aliases and functions defined there are not available to non-login
shells, e.g. when using screen or tmux.
If the ENV environment variable exists (exported by /etc/profile or
~/.profile) and references an existing file, then all interactive shells
(login or non-login) will read that file as well.
This sets the ENV environment variable in /etc/profile, pointing to
/etc/shinit.
This also adds /etc/shinit, which:
* Contains alias and function definitions originally in /etc/profile
* Sources /etc/mkshrc if the user is using mksh (also originally in
/etc/profile), as /etc/mkshrc is meant for all interactive shells
* Sources ~/.mkshrc if the user is using mksh, to compensate for the
fact that mksh will not read ~/.mkshrc if ENV is set
* Sources ~/.shinit if the user is not using mksh
This also removes the shebang from /etc/profile, as the file is sourced,
not executed.

Based on bug #18206 sysupgrade can lead to loss of password information in
certain situations. Most likely all users who will upgrade from versions
r43017-43040, will lose their current passwords. :-(
https://dev.openwrt.org/ticket/18206
Currently /etc/shadow is defined as a conffile in base-files:
https://dev.openwrt.org/browser/trunk/package/base-files/Makefile#L37
But it is not defined in the default list of essential files to keep in
sysupgrade:
https://dev.openwrt.org/browser/trunk/package/base-files/files/lib/upgrade/keep.d/base-files-essential
If exporting conffiles info fails, /etc/shadow can get lost.
Shadow passwords are now the default, so saying that preserving /etc/passwd
is essential while /etc/shadow is not, makes no sense.
The attached patch adds /etc/shadow to the list of essential files.
