docsettings can be stored either as a sidecar file (prefered, when
possible), or as a .lua file in the koreader/history/ folder (good,
when book is in a read-only directory where we can't create the
.sdr/ directory).
They are managed correctly if for some reason, the book directory
becomes writable: the docsettings in history/ is read, used, and
removed when a docsetting in a .sdr/ can be saved.
These docsettings in koreader/history/ contribute to the History
list build: they are put it in history.lua, and the duplicates
on followups history.lua builds are removed.
This fix a crash when a book is in a read-only directory.
Also fix History containing strange entries like "Book.epub.lua",
that came from the koreader/history/book.epub.lua.old backup,
that weren't removed as they are not a duplicate.

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`.
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.
