On Linux maximum data size for sendfile call is 0x7ffff000: 

sendfile() will transfer at most 0x7ffff000 (2,147,479,552) bytes,  returning  the  number  of  bytes  actually
transferred.  (This is true on both 32-bit and 64-bit systems.)

Limiting max block size to this value on all OSes makes sense: splitting transferring the very huge file into several syscalls doesn't hurt performance anyway.

Windows uses DWORD for size in TransmitFile, so the size is limited as well.
