Similarly to the alg_flag (which can be set by text), the ver_flag
is able to select the WPA version which will be sent to the Wi-Fi
driver through the `IW_AUTH_WPA_VERSION` command. A new bit field
(IW_AUTH_WPA_VERSION_WPA3) was created to indicate WPA3 is set.
It's up to the arch's Wi-Fi driver to implement handling of this
new bit field and config the underlying driver to handle WPA3 on
AP and/or STA mode.
This implementation doesn't interfere with commonly used commands.
`wapi psk wlan0 mypasswd 3` still selects CCMP algorithm and WPA2
and is equivalent to `wapi psk wlan0 mypasswd 3 WPA_VER_2`.
One can use `wapi psk wlan0 mypasswd 3 WPA_VER_3` to set WPA3.
Add the `WAPI_ESSID_DELAY_ON` member of the `wapi_essid_flag_e`
enum to its textual counterpart in `g_wapi_essid_flags`. This
enables `wapi`'s usage to describe it properly.
1. correct check of return value
----------------------
* Name: ioctl
...
* Returned Value:
* >=0 on success (positive non-zero values are cmd-specific)
* -1 on failure with errno set properly:
2. country code length should contain LF

The current essid setting(SIOCSIWESSID) are not satisfactory in case
of specified bssid connection, if there are multiple essids with same name,
we need additional bssid information to connect to the specified softap.
The extended flag "WAPI_ESSID_DELAY_ON" instructs the driver to delay the
connection behavior of essid, so that which can accept more accurate
information before generating a connection.
About flow of wapi command, drivers that support WAPI_ESSID_DELAY_ON semantics
will have the following behavior changes:
1. Station mode without bssid set:
$ ifup wlan0
$ wapi mode wlan0 2
$ wapi psk wlan0 12345678 3
$ wapi essid wlan0 archer 1
$ renew wlan0
2. Station mode with bssid set:
$ ifup wlan0
$ wapi mode wlan0 2
$ wapi psk wlan0 12345678 3
$ wapi essid wlan0 archer 2 <----- WAPI_ESSID_DELAY_ON will indicate the driver delay
$ the connection event late to bssid set (SIOCSIWAP).
$ wapi ap wlan0 ec:41:18:e0:76:7e
$ renew wlan0
