There are quite a few places in the current implementation where a nul
terminated string is generated from binary data. Add a helper function
to simplify the code a bit.

The new ssid2 parameter can be used as an alternative mechanism for
configuring SSID for hostapd. It uses the same formats that
wpa_supplicant uses in the configuration file for strings.

Instead of masking out non-ASCII characters with underscores, espace the
SSID data using rules compatible with printf.
Signed-hostap: Jouni Malinen <j@w1.fi>
This can be used to build ASCII strings from binary data that is
more likely to use ASCII (i.e., text format is more natural
option than hexdump, but there is possibility of some non-ASCII
characters).
Signed-hostap: Jouni Malinen <j@w1.fi>
This can be used by external programs (e.g., wlantest_cli) to inject
raw frames (hex dump of the frame header and body). The data can be
requested to be sent as-is or protected with the current key.
This version of the MAC address parser allows number of different
string formats for the address (e.g., 00:11:22:33:44:55, 0011.2233.4455,
001122334455, 00-11-22-33-44-55). It returns the number of characters
used from the input string in case of success.
gcc 4.4 ends up generating strict-aliasing warnings about some very common
networking socket uses that do not really result in a real problem and
cannot be easily avoided with union-based type-punning due to struct
definitions including another struct in system header files. To avoid having
to fully disable strict-aliasing warnings, provide a mechanism to hide the
typecast from aliasing for now. A cleaner solution will hopefully be found
in the future to handle these cases.
