The printf() about the number of links on a page is very useful, but
only for debugging. As other instances of debugging printf() in djvu.c
and pdf.c are commented out, it seemed consistent to do the same with
this one.
This is rough first draft, and provides just dump of all links
available on pdf page. Binding to Shift+L is temporary and just for
debugging!
Conflicts:
pdfreader.lua
unireader.lua
1. Remove unused "-lsdtc++" from the compilation stage as no linking is
done then.
2. Add our standard CFLAGS to the compilation of cre.cpp which brings in
-O3 -march=armv6 which enables optimizations.
It seemed strange that we compile a cpp file with gcc (as opposed to
g++), but I left it as is for now.
1. Make "-d" switch passed to reader.lua enable all debugging
2. Enable debugging for now (development stage) to preserve the current
behaviour. But for the production release I advise to: a) disable it by
not passing "-d" and b) redirect standard output (not just standard
error) of reader.lua to crash.log in kpdf.sh
3. Comment out debug printf()s in pdf.c

reader.lua
Instead of calling lfs.mkdir() to create "./history" and "./screenshots"
at runtime it is easier to create them at package build time.
I hesitated whether to add "./clipboard" to this list but decided
against it as we can perhaps change current directory and then
all the code manipulating clipboard would break, so I left it as is.
Conflicts:
filechooser.lua
screen.lua
settings.lua
1. Don't build xmltools in the emulator
2. Remove duplicate --disable-desktopfiles
3. Don't build LFS support. The largest DjVu file I have ever published
was a highres facsimile edition of the London Walton Polyglot (1657)
which was a "mere" 1GB in size and I don't think anyone produced
anything bigger. Besides, storing DjVu files >2GB in size (even if
they existed, which I doubt) on a Kindle with only 3GB total storage
space is _exceedingly_ unlikely.
1. Enhance FileInfo:FileSize() to handle gigabytes and rename it to FileInfo:FormatSize() as it is not just for file sizes.
2. Add "Free space" field to file info because it is useful to see it when deciding whether to remove this file or not.

fileinfo.lua
djvu pixel format on each redraw of the page as this can be done once on open and close
of the document. Also, set dither bits to 4 to help djvulibre choose the most
optimal dithering algorithm for the Kindle. Also, make coding style of "if(" -> "if ("
consistent (both instances were used, but "if (" was more frequent).
Conflicts:
djvu.c
Also added support for all other rendering modes handled by djvulibre.
Also made the message print a human-readable description of the mode rather than just the number.
Conflicts:
djvureader.lua
unireader.lua
a) add support for switching the rendering mode between B&W (default, 1) and COLOUR (0) values.
b) handle the gamma values correctly.
