Josef Weidendorfer db860c7cdc Add a format marker to callgrind files ...

KCachegrind currently uses a quick format detection before
actually loading a file, and checks for a line starting with
"events:" in the first 2kB for that. This obviously is fragile,
as shown by an internal bug report by Philippe: before the
"events" line, Callgrind puts a "cmd:" line with the command
line. If this is very long, the detection fails and the file
does not get loaded at all.

While KCachegrind would not need to have this quick format
check at all, it is useful if multiple input format filters
get supported at some point, to automatically select the
correct filter.

Further, for the "file" command, for file managers and
desktop environments, having an unique way to detect a
file format is important.

It is not too late to fix this issue for the callgrind format.
