- Replace all users of `$(RIOTBASE)/build` with the already present
`$(BUILD_DIR)` variable
- Replace all users of `$(BUILD_DIR)/pkg` with the already present
`$(PKGDIRBASE)` variable
- Create a `CACHEDIR.TAG` file in the `$(BUILD_DIR)`
Makefiles don't do comments, so these were forwarded into the variable.
*Most* users would expand the arguments to a shell where it'd be
ignored, but not all of them.

(This is also where the one version that is added here was removed).
- most were trivial
- missing group close or open
- extra space
- no doxygen comment
- name commad might open an implicit group
this hould also be implicit cosed but does not happen somtimes
- crazy: internal declared groups have to be closed internal
Enables the SDL driver for LVGL to utilize a user prescribed width/height for display resolution when utilizing SDL, or rely on the SDL_HOR/VER_RES provided by lv_drv_conf.h in lv_drivers
Using a lower priority than of the main thread would make
the LVGL thread to preempt the main thread, for example,
if you do a `xtimer_msleep(200);` on the main thread
giving any chance for the LVGL thread to preempt it
while working with LVGL on the main thread would
make the CPU crash.
To reproduce the bug just create various widgets, and fill
them with data from a sensor that "waits" for data to be ready.

Replace direct accesses to sched_active_thread and sched_active_pid with
the helper functions thread_getpid() and thread_get_active(). This serves
two purposes:
1. It makes accidental writes to those variable from outside core less likely.
2. Casting off the volatile qualifier is now well contained to those two
functions
