[bug-GNUnet] gnunet doesn't handle files larger than 2^32 bytes correctly

[C. Dominik Bodi]

Hello,

I've found a discrepancy between the file size reported using gnunet-search 
and the file of the size inserted.

For instance, the 1st amd64 DVD of the Debian 4.0 r4a release:
4690843648 debian-40r4a-amd64-DVD-1.iso
gnunet-insert and gnunet-search report URI
gnunet://ecrs/chk/2P5HV6726BM4P76NGL67MO3UL9SVOI1Q04T0EM07QPRER4HMNU6AM5UHJ50FSUTE4J16NFTV812P43P024I8F1TUVFGLI0QJQ751UO8.NNF7H4N32GMEEDTICAEC808C45OBVLEOQDJG54SEFSCEB0RCQK0AN5G0BG3ATA1U6HCLS8V0FCM144UPQTQCEE8K0SR28BJPSAU16DG.4690843648

However, gnunet-search says the file is 395.88 MB large. Coincidentally, when 
using decimal MB, this is almost exactly the remainder result when dividing 
the correct file size by 2^32.

It seems for some reason either gnunet-insert or another part of the gnunet 
system is not able to cope with files larger than 2^32. Seems the variables 
storing the file sizes are 32 bits only.

I'm using gnunet 0.8.0b on a Debian unstable (sid) system.
