Cleanup fg_pcap.c
Move create_output() into print_interval_report()

In follow up patches print_interval_report() will be cleaned up by using
asprintf() instead of fixed buffers
Reorganize print_interval_report() to increase readability
Delete some static buffers in print_interval_report()
Factor out logic for calculating column state

Instead for having this logic twice in create_column() and
create_column_str(), factor the logic out into a new function
column_width_changed().
[Trivial] Rename variables to increase readability
Coding style - apply C99 standard in create_column[_str]()
Delete remaining static buffers in print_interval_report()
Fix bug introduced by commit 896b6ec.

Return values of create_column() were accidentally overridden each time the
function was called. Instead the return values must be XORed.
Unify column width calculation

Both functions create_column() and create_column_str() determine now
the column width in the same way. As a follow up we can now factor
out the header creation in create_column[_str](), which avoid the code
duplication.
