This removes the fast_start parameter from the rc_pid parameters
information and instead uses the parameter macro when initializing
the rc_pid state. Since the parameter is only used on initialization,
there is no point of making exporting it via debugfs. This also fixes
uninitialized memory references to the fast_start and norm_offset
parameters detected by the kmemcheck utility. Thanks to Vegard Nossum
for reporting the bug.

Fix the rate control interval definition. Thanks to Mattias Nissler for
spotting this out.

Set a better value for percentage target for failed frames. The previous value
slowed down too much rate increases in case of permanently low activity. While
at it, increase readability.

Export the non-shifted target_pf value to debugfs, so that it's human-readable.

This adds all the tunable parameters used by rc80211_pid to debugfs for easy
testing and tuning.

This adds a new debugfs file from which rate control relevant events can be
read one event per line. The output includes the current time, so graphs can be
created showing the rate control parameters. This helps in evaluating and
tuning rate control parameters. While at it, we split headers and code for
better readability.
