Which I broke the last time I touched this.
NOTE: I'm not quire sure why the bbsave/bbrestore on stop/resume did a
double check (screensaver & charging), because that effectiely disabled
it when charging, which I don't quite understand...
Also makes sure the needsScreenRefreshAfterResume flag is honored on
Kindles, because we need it on FW >= 5.7.2
Note that this *breaks* the behavior with passcode enabled, which was
unwittingly fixed in said previous changes...
re #1811
When launching KOReader with the framework up from KUAL...
Our gentle hide/unhide method doesn't work anymore, which leads to
various issues, the most obvious being not getting a refresh to the
default UI on exit...
Properly refresh the screen when exiting with the framework running.
The lua code to handle that is called while cvm is SIGSTOPP'ed, so it
doesn't help.
Thanks to @Markismus's questions, I realized that some of what i thought
was true, wasn't.
First, pkill is a terrible idea to check for interpreted scripts.
Second, pidof is also potentially not that great for interpreted
scripts, because it'll only work with a shebang, and one that is
following the Linux syntax.
We don't have the full version with the -x to paper over that,
so use pgrep -f instead.

for the gory details.
It turns out that one of our mupdf patch reads the FONTDIR env var
and uses it in a totally different way so we will use another env var
EXT_FONT_DIR to define external font directory for different platforms.
to support custom font directory for EPUB documents
Now Koreader could find fonts in the "fonts" directory in the USB root
directory of kindle, Kobo and PocketBook devices, thus no need to copy
fonts to "koreader/fonts" directory.
