user-info: import from Gentoo & adjust to CrOS APIs
We use egetent from our user.eclass since it handles our account db,
and it has a compatible API. All other functions are imported as-is
except for egetgroups which is disabled. Nothing in Gentoo uses it,
and the Gentoo implementation doesn't work well with our setup.
The egethome & egetshell funcs are duplicated between the user eclasses
for now, but since they're implemented the same, it isn't a big deal.
We have to clean up some ebuilds in the tree before we can delete from
our user.eclass.
