alignment warnings are anal and seem to not like casting allocated
structs nicely ... but they are noise that hides real issues, so
silence these as these casts/ptrs are ok after inspection.
display really isn't uninitialized due to the logic, but compielr is
kind of right in theory... but less warnings is better so we fix the
real problems more easily. fix.
so we cast a lot of ptrs to other types as that is then the actual
type of the object. all these objects are allocated by malloc nad
friends so this is ok. but gcc on arm is not happy and warns. maybe it
assume this ptr could be to an element in an array of structs of this
type and so on thus will have specific alignment enforced by compiler
but our casting may disturb it? anyway. cast via void first fixes it.
we can focus on other real warnings and errors instead.
gcc on arm is actually validly complaining about us using int * ptrs
to point to char * data and thus it likely be unaligned, so work in
reverse. make the data int * aligned and when needed mess with it as
char * data byte by byte. warnings gone.
this avoids conflicts with efl internals, which will break entirely
when DISPLAY is set under wayland, and xwayland internals, which will
abort immediately when efl tries to connect to it during its init phase

this is an easy format string attack vector which serves no purpose
that I can fathom. the commit log where it was added it also made
no mention of this, as it was done in a seemingly-unrelated feature

So yeah, I've literally used sed to replace every occurrence of
ecore_time_add() with ecore_timer_loop_add() because I'm reasonably
confident that no part of E has a legitimate need for timer based on the
exact current time.
It would be really nice if I'm not wrong. :)
The reason for this is the incredible spew of clock_gettime() calls I'm
seeing on an ARM system (that should have a vdso for gettime, but...)
This can amount to thousands of system calls per second.
