- Drop hires_[nm]s clocks, rename hires.h to clock.h.
- Implement clk_t class as an extensible clock class in new file clock.cc.
- Introduce get_clock(clock_id) returning a pointer to the clk_t instance
for clock_id. Provide the following methods along the lines of the former
hires classes:
void clk_t::nsecs (struct timespec *);
ULONGLONG clk_t::nsecs ();
LONGLONG clk_t::usecs ();
LONGLONG clk_t::msecs ();
void clk_t::resolution (struct timespec *);
- Add CLOCK_REALTIME_COARSE, CLOCK_MONOTONIC_RAW, CLOCK_MONOTONIC_COARSE
and CLOCK_BOOTTIME clocks.
- Allow clock_nanosleep, pthread_condattr_setclock and timer_create to use
all new clocks (both clocks should be usable with a small tweak, though).
- Bump DLL major version to 2.12.

Regression introduced with 2.11.0:
The failure paths in socket, socketpair and accept4 functions and
methods accidentally release *unused* cygheap_fdmanip objects. The
subsequently called dtable::release method was designed to be called for
*used* cygheap_fdmanip objects only. Using them on unused objects leads
to NULL pointer member dereferencing.
Worse, the inet/local accept4 methods only release the cygheap_fdmanip
object but neglect to delete the just created fhandler_socket_* object.
Fix this by removing the erroneous release calls in the aforementioned
failure paths and delete the fhandler_socket_* object in accept4 instead.

* Change set_socket_type/get_socket_type to virtual methods
* Move various variables into af_unix_shmem_t
* Change sun_name_t to match new usage pattern
* Move shut_state definition and add a name for the 0 value
* Allow marking packet as administrative packet. This allows
filtering out info packets exchange between peers and tweak
data accordingly.
* Rename send_my_name to send_sock_info and send credentials
if not called from bind (so the socket was already connected)
* Handle SO_PASSCRED in setsockopt/getsockopt
* Add input size checking to setsockopt/getsockopt
* Use NT functions where appropriate

E.g. arm ABI requires -fshort-enums for bare-metal toolchains.
Given there are only 29 category enums, the compiler chooses an
8 bit enum type, so a size of 11 bits for the bitfield leads to
a compile time error:
error: width of 'cat' exceeds its type
enum category cat: 11;
^~~
Fix this by aligning the size of the category members to byte
borders.

Per-socket info in fhandler isn't correctly shared between multiple
instances of th same descriptor. Implement a basic shared info which
is shared between all instances of a socket.
This also requires to move the fhandler_socket status bits into
fhandler_socket_wsock since the data is moved to the shared region
for AF_UNIX sockets.
Also, drop backing file requirement for socketpair server socket.
This will be handled differently in recvmsg/sendmsg.

* Use correct cygwait/WFSO invocation to not die on cancel and signals
uncontrolled.
* Manage io handles under io_lock.
* Copy peer address to user space under SEH to avoid a resource leak.

Using TerminateThread potentially leaks resources. In our case,
the connect wait thread may be forcefully terminated after
having successfully opened a client side pipe handle. If this
occurs, we have a stale pipe server instance, so the pipe will
never be closed as long as the process lives.
Avoid this by changing the npfs handle to non-blocking, so we can
wait on a termination event object from inside the thread itself
and cleanly exit from the thread instead of terminating.

Depending on the exact circumstances, some erros are indicated
by different status codes. Add helper macros to handle them
together.

The handle to the device is never needed. As the name impies,
FSCTL_PIPE_WAIT works on the file system, not on the device level.
Drop opening the device and make sure to open only one handle to NPFS.

They are only used there anyway and it allows to use the AF_UNIX
macro without tweaking header files. While at it, improve
both constructors. The default constructor now creates the name
of an unnamed socket, the constructor taking parameters carefully
checks its input.
