luactl & Lua standard libraries

[Guilherme Salazar <gmesalazar%gmail.com@localhost>]

Hi folks,

kernel Lua states created with luactl(8) are created empty. There has
been some discussion about it.

It would be nice to add an option to luactl to allow loading of Lua
standard libraries -- by calling luaL_openlibs on the Lua state. I
have added an option `-s` to `luactl require` that does this. See [1]

To make it clear, the following creates an empty kernel Lua state named s0:

    luactl create s0

What I propose is:

    luactl create s0
    luactl -s require s0

or, equivalently,

    luactl -cs require s0

(-c option creates s0 if it doesn't exist and then -s calls luaL_openlibs on s0)

Comments?
