Cygwin is a Posix platform to the extent possible.  It should use the
Posix API except in special circumstances.

77bd0a6458 Add variation coords to shape_plan proposal 
This is the root cause of bug worked around in 19e77e01bc.

Still no shape plan caching for variations though.

f521a28b4a Embed hb_ot_shape_plan_t into hb_shape_plan_t 
No other shaper will need shape_plan_data, by definition.  So, remove
abstraction layer and always create hb_ot_shape_plan_t as part of
hb_shape_plan_t.

2ee1d9f555 [blob] Change null object memory mode to DUPLICATE 
We never rely on that being equal to readonly.  Just not being
writable.  Maybe not even that given that the object is inert.

In prep for next commit, using default null pool.
