69339c7a97 util: guard against NULL 'freqs' in scan_freq_set_free 
Since this can be used with the _auto_ macro it must be able to handle
a NULL input for error paths.

0bc44a038b util: add scan_freq_set_clone 
This creates a new scan_freq_set from an input set which only contains
frequencies from bands included in the mask.

5b6f1e3662 util: add 6GHz support to scan_freq_set* APIs 
The 6GHz channels are stored and accessed identically to 5GHz,
just using a separate uintset object.

ff6961fbc4 band: add BAND_FREQ_6_GHZ 
This is a new band defined in the WiFi 6E (ax) amendment. A completely
new value is needed due to channel reuse between 2.4/5 and 6GHz.

util.c needed minimal updating to prevent compile errors which will
be fixed later to actually handle this band. WSC also needed a case
added for 6GHz but the spec does not outline any RF Band value for
6GHz so the 5GHz value will be returned in this case.

fe95cbe077 treewide: Various style fixups 
- Mostly problems with whitespace:
	- Use of spaces instead of tabs
	- Stray spaces before closing ')
	- Missing spaces

- Missing 'void' from function declarations & definitions that
  take no arguments.

- Wrong indentation level

modules requiring unit testing

99923c90da util: Be more paranoid when parsing addresses 
Add a check to make sure that sscanf reads all 6 bytes of the address as
well.

34560120f9 util: add bounds check to util_get_{domain,username} 
Replace uses of strcpy by the safer l_strlcpy.  Note that both of these
functions can only be called with a buffer of max 253 bytes (the
identity string), so this is purely a precautionary measure.

65f279dc1e util: Use memcpy instead of strncpy 
The sub-string copied here will never have NULL terminators, so use
memcpy here to make this clearer.

abcc9f1647 util: add APIs to get username/domain from identity 
mschaputil already had similar functionality, but ERP will need this
as well. These two functions will also handle identities with either
'@' or '\' to separate the user and domain.

UTF8. Replace each char that is not UTF8 compatible with the UTF8
replacement symbol.
