Tomasz Grabiec f553db69f7 cached_file: Issue single I/O for the whole read range on miss 
Currently, reading a page range would issue I/O for each missing
page. This is inefficient, better to issue a single I/O for the whole
range and populate cache from that.

As an optimization, issue a single I/O if the first page is missing.

This is important for index reads which optimistically try to read
32KB of index file to read the partition index page.
