Add support for negotiating WNM Collocated Interference Reporting. This allows hostapd to request associated STAs to report their collocated interference information and wpa_supplicant to process such request and reporting. The actual values (Collocated Interference Report Elements) are out of scope of hostapd and wpa_supplicant, i.e., external components are expected to generated and process these. For hostapd/AP, this mechanism is enabled by setting coloc_intf_reporting=1 in configuration. STAs are requested to perform reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report Timeout>" control interface command. The received reports are indicated as control interface events "COLOC-INTF-REPORT <addr> <dialog token> <hexdump of report elements>". For wpa_supplicant/STA, this mechanism is enabled by setting coloc_intf_reporting=1 in configuration and setting Collocated Interference Report Elements as a hexdump with "SET coloc_intf_elems <hexdump>" control interface command. The hexdump can contain one or more Collocated Interference Report Elements (each including the information element header). For additional testing purposes, received requests are reported with "COLOC-INTF-REQ <dialog token> <automatic report enabled> <report timeout>" control interface events and unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>". This commit adds support for reporting changes in the collocated interference (Automatic Report Enabled == 1 and partial 3), but not for periodic reports (2 and other part of 3).
