Brandon Williams f0dd042148 attr: reformat git_attr_set_direction() function ...

Move the 'git_attr_set_direction()' up to be closer to the variables
that it modifies as well as a small formatting by renaming the variable
'new' to 'new_direction' so that it is more descriptive.

Update the comment about how 'direction' is used to read the state of
the world.  It should be noted that callers of
'git_attr_set_direction()' should ensure that other threads are not
making calls into the attribute system until after the call to
'git_attr_set_direction()' completes.  This function essentially acts as
reset button for the attribute system and should be handled with care.
