gdbus, win32: move most W32 dbus autolaunch code to gdbusprivate
This allows referencig them from more than single .c file. Implementation moved without changes from gdbusaddress.c to gdbusprivate.c g_win32_run_session_bus signature also kept, so ABI unchanged.

|

* Since the dll path may have spaces, it is used as working directory,

* "C:\Windows\System32\rundll32.exe" .\libgio-2.0-0.dll,g_win32_run_session_bus
|

*
|

* Using relative path to dll rises a question if correct dll is loaded.
|
||||
* According to docs if relative path like .\libgio-2.0-0.dll is passed
|
||||
* the System32 directory may be searched before current directory:
|
||||
* https://docs.microsoft.com/en-us/windows/desktop/dlls/dynamic-link-library-search-order#standard-search-order-for-desktop-applications
|

* Internally rundll32 uses "undefined behavior" parameter combination
|
||||
* LoadLibraryExW(".\libgio-2.0-0.dll", NULL, LOAD_WITH_ALTERED_SEARCH_PATH)
|
||||
* Actual testing shows that if relative name starts from ".\"
|
||||
* the current directory is searched before System32 (win7, win10 1607).
|
||||
* So wrong dll would be loaded only if the BOTH of the following holds:
|
||||
* - rundll32 will change so it would prefer system32 even for .\ paths
|
||||
* - some app would place libgio-2.0-0.dll in system32 directory
|
||||
*
|
||||
* In point of that using .\libgio-2.0-0.dll looks fine.

|

* Since the dll path may have spaces, it is used as working directory,

* "C:\Windows\System32\rundll32.exe" .\libgio-2.0-0.dll,g_win32_run_session_bus
|
||||
*
|
||||
* Using relative path to dll rises a question if correct dll is loaded.
|
||||
* According to docs if relative path like .\libgio-2.0-0.dll is passed
|
||||
* the System32 directory may be searched before current directory:
|
||||
* https://docs.microsoft.com/en-us/windows/desktop/dlls/dynamic-link-library-search-order#standard-search-order-for-desktop-applications
|

* Internally rundll32 uses "undefined behavior" parameter combination
|
||||
* LoadLibraryExW(".\libgio-2.0-0.dll", NULL, LOAD_WITH_ALTERED_SEARCH_PATH)
|
||||
* Actual testing shows that if relative name starts from ".\"
|
||||
* the current directory is searched before System32 (win7, win10 1607).
|
||||
* So wrong dll would be loaded only if the BOTH of the following holds:
|
||||
* - rundll32 will change so it would prefer system32 even for .\ paths
|
||||
* - some app would place libgio-2.0-0.dll in system32 directory
|
||||
*
|
||||
* In point of that using .\libgio-2.0-0.dll looks fine.
