Cygwin: rename NSIG to _NSIG, change visibility of NSIG to MISC

Browse Source 
NSIG is a deprecated symbol only visible under MISC visibility.
_NSIG is used widely instead, and on most systems NSIG is
defined in terms of _NSIG.

Follow suit: Change NSIG to _NSIG throughout and change visiblity
of NSIG to be defined only in __MISC_VISIBLE case.
