Andrey Semashev ae458c7884 Switch to POSIX API on Cygwin. ...

This follows other Boost libraries (in particular, Boost.System) in
treating Cygwin as a POSIX platform rather than Windows. This is
a breaking change, but apparently downstream Boost.Filesystem packages
on Cygwin are patched to the same effect.

As part of this change, AT_NO_AUTOMOUNT is made an optional requirement
to enable POSIX *at APIs. This flag is not POSIX-standard and is not
supported on Cygwin, while *at APIs are.
