4b0470210d api: cleanup driver selection logic
With all the platforms (including ARM) having at least one driver now,
the dead-code removal #ifdef-s are no longer required.

bf4eabb4ca api: switch to private heap
We must not use the process heap, as it is changeable. Client may change
it causing our HeapFree() to use wrong heap.

d04721dee6 api: test the temporary driver idea
1. Add driver to the store: SetupCopyOEMInfW()
2. Create the adapter using explicit path to .inf file: DI_ENUMSINGLEINF
3. Delete all Wintun drivers from the store.

This is a subject of further research:

- It appears those adapters survive a reboot. So, Windows must store the
  driver somewhere on the disk and the driver removal is not completed.
  If the driver removal is not completed until there are existing
  adapters, this is excellent, as it will provide a self-cleanup.

- Test multiple adapters with different driver versions. Which driver
  wins?

- Are other Wintun adapters interrupted when adding a new one?

- Test Windows 7 behaviour.

ac6db7788a api: move documentation to .h and discontinue on static functions
While Doxygen correctly locates the function documentation when it is
written directly preceding the function body, Microsoft Visual Studio
IDE does not. The former requires the documentation to precede the
function declaration.

When an internal function logs an error and its cause, it bloats the log
when the caller logs the cause again.

78b7a01eb3 api: simplify logger macros names
WINTUN_LOGGER_... => LOGGER_... => LOG_...

Those macros are internal, so they don/t need to start with WINTUN_...

Replacing the noun LOGGER_... with the verb LOG_... makes the code more
natural to read now.

e157d421ec api: implement driver version extraction from .inf file
With installer.dll the installer did the decision whether to install or
upgrade the driver according to installer.dll version and hash stored in
registry by MSM.

With wintun.dll we need to know, which version of Wintun driver we are
packing in the resources to decide about driver upgrade. The most
accurate source of the driver version is the DriverVer directive in
[Version] section of the driver's .inf file.
