[issue50] gpgme is not largefile-safe

[Marc Mutz]

New submission from Marc Mutz <marc at klaralvdalens-datakonsult.se>:

gpgme uses off_t, size_t et al in it's public function signatures, but fails to 
provide two versions for each such function (one for sizeof(off_t) == 8 and one 
for sizeof(off_t) == 4). 
 
Because on 32bit-Linux, application developers are free to choose their off_t's 
size with e.g. -D_FILE_OFFSET_BITS=64, this leads to very subtle bugs in 
applications using an eight-byte off_t. 
 
As an example, try running make check in libkdenetwork/qgpgme/tests. The seeks 
fail because gpgme and qgpgme's off_t's differ in size (gpgme: 4; qgpgme: 8). 
Thus callbacks are passed corrupted data and fail for one reason or another. 
 
Thanks to dfaure for finding this one.
