What's new:
-----------
- Introduce reading passwd/group entries directly from SAM/AD, thus allowing
to do without /etc/passwd and /etc/group files. Introduce /etc/nsswitch.conf
file to configure passwd/group handling.
- /proc/cygdrive is a new symlink pointing to the current cygdrive prefix.
This can be utilized in scripts to access paths via cygdrive prefix, even
if the cygdrive prefix has been changed by the user.
- /proc/partitions now prints the windows mount points the device is mounted
on. This allows to recognize the underlying Windows devices of the Cygwin
raw device names.
- New API: quotactl, designed after the Linux/BSD function, but severly
restricted: Windows only supports user block quotas on NTFS, no group
quotas, no inode quotas, no time constraints.
- New APIs: ffsl, ffsll (Linux extensions).
What changed:
-------------
- New internal exception handling based on SEH on 64 bit Cygwin.
- Revamp Solaris ACL implementation to more closely work like POSIX ACLs
are supposed to work. Finally implement a CLASS_OBJ emulation. Update
getfacl(1)/setfacl(1) accordingly.
- Drop the current working directory from the default DLL search path in
favor of Cygwin's /bin dir.
- Improve various header files for C++- and standards-compliance.
- Doug Lea malloc implementation update from 2.8.3 to the latest 2.8.6.
Bug Fixes
---------
- Per POSIX, dirfd(3) now returns EINVAL rather than EBADF on invalid
directory stream.
- Fix a resource leak in rmdir(2).
- Fix fchmod(2)/fchown(2)/fsetxattr(2) in case the file got renamed after
open and before calling one of the affected functions.

Addresses: https://cygwin.com/ml/cygwin/2014-06/msg00425.html
- Fix chown(2) on ptys in a corner case.
- Generate correct error when a path is inaccessible due to missing permissions.
Addresses: https://cygwin.com/ml/cygwin-developers/2014-10/msg00010.html
- Don't hang in accept calls if socket is no listener. Set errno to EINVAL
instead. Don't hang in read/recv/recvfrom/recvmsg calls if socket is
connection oriented and not connected. Set errno to ENOTCONN instead.
- Don't allow seeking on serial lines and sockets. Set errno to ESPIPE
instead.
Addresses: https://cygwin.com/ml/cygwin/2014-08/msg00319.html
- Fix output of /proc/<PID>/statm.
- Fix a SEGV in cygcheck if the environment variable COMSPEC is not, or
incorrectly set.
