[Lorenzo Bianconi]

Introduce Automated Frequency Coordination (AFC) support for UNII-5 and UNII-7
6GHz bands.

coordinator on UNII-5 or UNII-7 6GHz bands.
AFCD and AFC hostapd client are tested with AFC DUT Test Harness [0].

Changes since v2:
- multiple fixes testing with AFC DUT Test Harness
Changes since v1:
- use unix socket instead of a tcp one
Changes since rfc:
- move curl connection to a dedicated afc daemon

  hostapd: afcd: add AFC daemon support
  hostapd: export hostapd_is_usable_chans utility routine
  hostapd: ap: add AFC client support
  hostapd: update TPE IE according to AFC
