new feature - polkit auth agent support partly in core (need to have
the pam setuid root auth tool respond via dbus) and partly a module
(the agent dbus protocol handling and setup as well as auth gui). this
took me a while even with all the docs to work out how polkit works...
it was really fussy and its data structs are an extra pain in the butt
to craft with eldbus, but i managed it. not everything is supported
but the core basics are there and this can be built on.
right now the gui is really basic, but does the job.
this should fix T6211 ensuring no drivers can cause a segfault at exit
time. this also happens to remove the enlightenment_sys -z option for
openbsd and unifies all the passwd checking into the single
enlightenment_ckpasswd binary util (that has ifdefs for openbsd,
freebsd and linux pam in it).
this simplifies code removing a mess of auth being done in multiple
places, removes special fork vs run 1 exe or a different exe in
different cases making it more maintainable. yes - this requires
enlightenment_ckpasswd to be setuid root, but it already was when it
was built.
@fix
all eina hash functions are now useless for any case where the hashed value needs to be stored, so it's necessary for e to provide its own hash function to use for password storage
after this commit, the new-but-invisible module "lokker" (or other custom loaded module) is in charge of creating all graphics for the lock screen, and it will be added to the user's config. failure to load a lockscreen module will just result in a black screen
desklock subsystem now handles all the pre/post lock stuff while the modules themselves are responsible for creating visuals and calling auth functions to determine whether to unlock the screen
