Just like commit e2ba732a16 ("selftests: fib_tests: sleep after
changing carrier"), wait one second to allow linkwatch to propagate the
carrier change to the stack.
There are two sets of carrier tests. The first slept after the carrier
was set to off, and when the second set ran, it was likely that the
linkwatch would be able to run again without much delay, reducing the
likelihood of a race. However, if you run 'fib_tests.sh -t carrier' on a
loop, you will quickly notice the failures.
Sleeping on the second set of tests make the failures go away.

Add a 'path' member to 'struct perf_data'. It will keep the configured
path for the data (const char *). The path in struct perf_data_file is
now dynamically allocated (duped) from it.
This scheme is useful/used in following patches where struct
perf_data::path holds the 'configure' directory path and struct
perf_data_file::path holds the allocated path for specific files.
Also it actually makes the code little simpler.

Add a new report to display top calls by elapsed time. It displays calls
in descending order of time elapsed between when the function was called
and when it returned.

If no selection is made on the 'Selected branches' dialog, then the
output is the same as the 'All branches' report. That is not really an
error, and is not desirable for future reports, so remove it.

Create new dialog data item classes to replace SQLTableDialogDataItem.
This separates out different dialog data items and makes it easier to
add new ones. SQLTableDialogDataItem is removed in a separate patch
because it makes the diff more readable.
