that these keys/signals are handled only when app calls read() or
select(). Now, these work even if app does not call read() or select().
- fchmodat(2) now has limited support for the AT_SYMLINK_NOFOLLOW flag.
- Cygwin now recognizes native Windows AF_UNIX sockets (as regular
files, not as socket files). This allows tools like 'ls' and 'rm'
to work.

- Utilize Windows 10 1809 FILE_DISPOSITION_IGNORE_READONLY_ATTRIBUTE
flag to allow simpler unlink of files with DOS readonly flags set.
- getdtablesize(3), sysconf(_SC_OPEN_MAX), and
getrlimit(RLIMIT_NOFILE) now return the true limit on the number of
open descriptors, 3200. Previously they returned the current size
of Cygwin's internal file descriptor table, which can grow
dynamically.
- facl(2) now fails with EBADF on a file opened with O_PATH.
