hardware_legacy: allow alternative vibrator implementations

The native vibrator code in libhardware_legacy assumes the vibrator
is always controlled by inputting timers into sysfs (at
/sys/class/timed_output/vibrator/enable). This isn't necessarily true,
there's an upcoming device which has the vibrator controlled by ioctl()
calls.

This patch lets the device configuration specify an alternative
vibrator implementation throught the variable BOARD_HAS_VIBRATOR_IMPLEMENTATION

That variable should point to a sourcefile that implements the vibrator
"int sendit(timeout_ms)" function, like this:

BOARD_HAS_VIBRATOR_IMPLEMENTATION := ../../device/vendor/model/vibrator.c

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
