	[extfs] fix inodes not being initialized above 4 GB
* So, as it happens, when assigning the product of two 32-bit variables into a 64-bit one, compilers default to being *DUMB* and, against all reasonable expectations, do not perform that multiplication as a 64-bit operation (even when the code is compiled as x64). Wow, that's really great decision making by compiler designers if I ever saw some... Whoever decided that C developers would much rather want truncation and 32-bit overflows, instead of the expected *LOGICAL* behaviour of conducting arithmetic operations as 64-bit when the result will be assigned to a 64-bit variable, need to be condemned to a lifetime of trying to help elderly folks trying to conduct simple computing tasks as a punishment... Anyhoo, nt_write_blk()'s offset.QuadPart = block * channel->block_size + nt_data->offset was overflowing 32-bit as soon as block * channel->block_size went over the 4 GB mark, with the disastrous results one can expect. Considering that this is code we practically lifted verbatim from e2fsprogs, I guess e2fsprogs' NT I/O manager was never properly tested with anything larger than a 4 GB. Awesome! * We fix the above by doing what unix_io.c does and setting the 32-bit read/write_blk() calls to be wrappers around their 64-bit counterpart (since, once you deal with a 64-bit block variable, the computation is conducted as 64-bit). * Also remove a bunch of stuff we don't need from config.h * Closes #1396
