Driver wrapper implementation (driver.h, drivers.c)

All hardware and driver dependent functionality is in separate C files that implement defined wrapper functions. Other parts of the hostapd are designed to be hardware, driver, and operating system independent.

Driver wrappers need to implement whatever calls are used in the target operating system/driver for controlling wireless LAN devices. As an example, in case of Linux, these are mostly some glue code and ioctl() calls and netlink message parsing for Linux Wireless Extensions (WE). Since features required for WPA were added only recently to Linux Wireless Extensions (in version 18), some driver specific code is used in number of driver interface implementations. These driver dependent parts can be replaced with generic code in driver_wext.c once the target driver includes full support for WE-18. After that, all Linux drivers, at least in theory, could use the same driver wrapper code.
