This workaround makes a reservation of mmap slots that are hopefully
near the address of `mcode_alloc_at`. Then it unmaps those slots and
lets luajit allocate a large slot for mcode.
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...
Currently only tested on Ubuntu-touch emulator with framework
ubuntu-sdk-14.10 for armhf.
The ubuntu-touch port is binary compatible with the Kobo port
major changes in this PR are:
1. rename the emulator device to sdl device since both the emulator
and the ubuntu-touch target use libsdl to handle input/output.
2. ubuntu-touch app has no write access to the installation dir so
all write-outs should be in a seperate dir definded in `datastorage`.
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.
To avoid potential issues with USBMS.
Namely, make sure CWD doesn't point to the userstore for persitent
processes.
Make sure wpa_supplicant doesn't try to use our own OpenSSL lib, which,
again, is in the userstore area.
Properly kill our dhcp client invocation on when killing WiFi
Also, some related fixes to the startup script:
Properly kill wpa_supplicant & the dhcp client when we kill
wifi before rebooting to nickel.
On kindle, kobo and pocketbook the data directory is the current
running directory but on Android the app is installed in system
defined location and users may have no access to that location.
The same circumstances should be true for the upcoming Koreader for
Ubuntu touch, so the data directory (in which tessdata, dictionaries,
global settings, persistant defaults and probably history data are
stored) could be stored in another place.
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.
cf.

for the gory details.
pkill probably only checks the actual name of the binary.
We were checking a shell script, which I'm guessing is not launched
via a shebang, so that name was actually an arg to sh, or something like
that.
Use pidof instead, which matches the full command line.
For some unknowable reason, restarting nickel on exit deadlocks on my
H2O, so, do a full reboot instead, at least *that* works.
I'm probably one of the only people running KO manually anyway...
Compatibility with KSM is resolved. Koreader will now work from any directory it is installed in.
KSM7 tweaks `koreader.sh` line 5 from a hardcoded path to the line used above. I've added the change in line 12 to allow OTA updating.
