Andrey Shinkevich 897dd0ec4f block: include supported_read_flags into BDS structure ...

Add the new member supported_read_flags to the BlockDriverState
structure. It will control the flags set for copy-on-read operations.
Make the block generic layer evaluate supported read flags before they
go to a block driver.
