wifi: Choose correct nvram file on Samsung hardware

 * Samsung's US devices have at least three different Wi-Fi variations.
 * The kernel driver writes out the variant in /data/.cid.info
 * macloader will prime this file
 * Read the file and choose the correct nvram_net.txt

ifdef usage of legacy audio enum conversion

Without this, devices compiling from source using this HAL layer
as a static whole library will break as they already use the new enum.

wifi: add suport for WIFI_EXT_MODULE

Some wifi modules have dependencies on others (for SDIO, usually).
Use WIFI_EXT_MODULE_PATH to specify such dependencies

wifi.c: allow devices to specify driver delay if needed

This appears to be needed on the Samsung exynos4 tablets in order to enable wifi within a reasonable amount of time.

libhardware_legacy: handle direct outputs during device switch

- Direct outputs like LPA, Tunnel and VoIP are opened during device
  switch. This results in a crash while opening the driver.
- This issue is fixed by preventing the opening of direct output
  during device switch.
- Added additional LOG to debug policy config issues

libhardware_legacy/wifi: add workaround for ar6000 driver

The ar6000 driver requires the interface to be brought up in order
for scanning to function. Without this change, the supplicant fails
on first activation of wifi, and will only connect successfully
after multiple retries. This workaround is also necessary to fix
Wi-Fi hotspot mode (in conjunction with another change to
system/netd).

Backported from CM7.
Fix build error caused by ar6000 workaround

Some devices don't specify DRIVER_MODULE_NAME or DRIVER_MODULE_PATH.
