When hardware or uCode problem occurs driver captures significant information from device to enable debugging. The format of this information is different between 3945 and 4965 and later devices, yet currently the 3945 uses the 4965 and later format. Fix this by adding a new library call that is initialized to the correct formatting routine based on device. This moves the iwlagn event and error log handling back to iwl-agn.c to make it part of iwlagn module. Also remove the 3945 sysfs file that triggers dump of event log - there is already a debugfs file that can do it for all drivers.

We keep track of where to write into a buffer by keeping a count of how much has been written so far. When writing to the buffer we thus take the buffer pointer and adding the count of what has been written so far. Keeping track of what has been written so far is done by incrementing this number every time something is written to the buffer with how much has been written at that time. Currently this number is incremented incorrectly when using the "hex_dump_to_buffer" call to add data to the buffer. Fix this by only adding what has been added to the buffer in that call instead of what has been added since beginning of buffer. Issue was discovered and discussed during testing of https://bugzilla.redhat.com/show_bug.cgi?id=464598 .

Depending on required latency requested by pm_qos (via mac80211) we can automatically adjust the sleep state. Also, mac80211 has a user-visible dynamic sleep feature where we are supposed to stay awake after sending/receiving frames to better receive response frames to our packets, this can be integrated into the sleep command. Currently, and this patch doesn't change that yet, we default to using sleep level 1 if PS is enabled. With a module parameter to iwlcore, automatic adjustment to changing network latency requirements can be enabled -- this isn't yet the default due to requiring more testing. The goal is to enable automatic adjustment and then go into the deepest possible sleep state possible depending on the networking latency requirements. This patch does, however, enable IEEE80211_HW_SUPPORTS_DYNAMIC_PS to avoid the double-timer (one in software and one in the device) when transmitting -- the exact timeout may be ignored but that is not of big concern. Note also that we keep the hard-coded power indices around for thermal throttling -- the specification of that calls for using the specified power levels. Those can also be selected in debugfs to allow easier testing of such parameters.

Some of the thermal throttle data structures and code are really very intermingled with the sleep (power) control code. They really do belong together in a way since the thermal throttle code uses powersaving to achieve its goal, but it's making it hard to work on the powersave code. Split this up to make that easier. I've also changed the antenna defines to an enum and used the same enum for RX and TX.

Add debugfs file to enable/disable HT40(40MHz) channel support. By default, 40MHz is supported if AP can support the function. By echo "1" to "disable_ht40" file, iwlwifi driver will disable the 40MHz support and only allow 20MHz channel. Because the information exchange happen during association time, so enable/disable ht40 channel only can be performed when it is not associated with AP.
