Ben Wijen 63e625853f Make sure temporary file handles are not inherited by child processes ...

When testing a merge driver which spawns a merge server (for future merges)
I got the following error:

    Rename from 'xxx/.git/index.lock' to 'xxx/.git/index' failed. Should I try again? (y/n)

Only after I stop the merge server the lock is released.
This is caused by windows handle inheritance.

Starting childs with bInheritHandles==FALSE does not work,
because no file handles would be inherited,
not even the hStdXxx handles in STARTUPINFO.

Opening every file with O_NOINHERIT does not work,
Since it is used by git-upload-pack for example,
which expects inherited handles.

This leaves us with only creating temp files with the O_NOINHERIT flag.
Which (currently) only used by lock_file which is exactly what we want.
