When using the --list option general errors where not properly reported, only errors related with the 'file'. Now they are reported, and 'file' is irrelevant. That reduces the rest of 'file' usage to nothing, therefore now only 'prefix' remains. Suggested by Johannes Schindelin.

As git functions currently use mmap with MAP_PRIVATE set only, this implementation supports only that mode for now. On Windows, offsets for memory mapped files need to match the allocation granularity. Take this into account when calculating the packed git- windowsize and file offsets. At the moment, the only function which makes use of offsets in conjunction with mmap is use_pack() in sha1-file.c. Git fast-import's code path tries to map a portion of the temporary packfile that exceeds the current filesize, i.e. offset+length is greater than the filesize. The NO_MMAP code worked with that since pread() just reads the file content until EOF and returns gracefully, while MapViewOfFile() aborts the mapping and returns 'Access Denied'. Working around that by determining the filesize and adjusting the length parameter.
