Damien Dejean 58eb905ad3 HS20: Support credentials with multiple home OIs 
Until now Hotspot 2.0 credentials were only supporting one home OI (with
roaming_consortium option) and one required home OI (with
required_roaming_consortium option). To improve the compliance with
Passpoint specification, add the support for multiple home and required
OIs.

The lists of OIs are provided using two new configuration options
home_ois and required_home_ois that expect a list of OIs formatted as
the roaming_consortiums list. It allows to keep the old options to avoid
breaking currently running configurations and better fits the vocabulary
used in the spec.

The OI match algorithm is updated to implement the behavior described in
Passpoint specification v3.2 section 9.1.2 (Home OIs nodes description
PerProviderSubscription/<X+>/HomeSP/HomeOIList/<X+>).

* Table of network configuration variables. This table is used to parse each

* that is inside a network block.
*
* This table is generated using the helper macros defined above and with
* generous help from the C pre-processor. The field name is stored as a string
* into .name and for STR and INT types, the offset of the target buffer within
* struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar
* offset to the field containing the length of the configuration variable.
* .param3 and .param4 can be used to mark the allowed range (length for STR
* and value for INT).
*
* For each configuration line in wpa_supplicant.conf, the parser goes through
* this table and select the entry that matches with the field name. The parser
* function (.parser) is then called to parse the actual value of the field.
*
* This kind of mechanism makes it easy to add new configuration parameters,
* since only one line needs to be added into this table and into the
* struct wpa_ssid definition if the new variable is either a string or
* integer. More complex types will need to use their own parser and writer
* functions.
