Our local ntsecapi.h wrapper corrects a bug in the definition of
SystemFunction036 which otherwise leads to crashes on 32 bit when
using RtlGenRandom. The fhandler_socket_local.cc file accidentally
included the incorrect w32api version of that file, rather than the
local wrapper. Fix it.

Certain tape drives (known example: QUANTUM_ULTRIUM-HH6) return
the non-standard ERROR_NOT_READY rather than ERROR_NO_MEDIA_IN_DRIVE
if no media is present. ERROR_NOT_READY is not documented as valid
return code from GetTapeStatus. Without handling this error code
Cygwin's tape code can't report an offline state to user space.
Fix this by converting ERROR_NOT_READY to ERROR_NO_MEDIA_IN_DRIVE
where appropriate.
Add a debug_printf to mtinfo_drive::get_status to allow requesting
user info without having to rebuild the DLL.

pthread_timedjoin_np returns ETIMEDOUT if a thread is still running,
not EBUSY as pthread_tryjoin_np.
Also, clean up initializing timeout in pthread_tryjoin_np.

- Move pthread_join to thread.cc to have all `join' calls in
the same file (pthread_timedjoin_np needs pthread_convert_abstime
which is static inline in thread.cc)
- Bump API version

* fhandler.h (class fhandler_socket_inet): Add variable bool oobinline.
* fhandler_socket_inet.cc (fhandler_socket_inet::fhandler_socket_inet):
Initialize variable oobinline.
(fhandler_socket_inet::recv_internal): Make the handling of OOB data
as consistent with POSIX as possible. Add simulation of inline mode
for OOB data as a workaround for broken winsock behavior.
(fhandler_socket_inet::setsockopt): Ditto.
(fhandler_socket_inet::getsockopt): Ditto.
(fhandler_socket_wsock::ioctl): Fix return value of SIOCATMARK command.
The return value of SIOCATMARK of winsock is almost opposite to
expectation.
* fhandler_socket_local.cc (fhandler_socket_local::recv_internal):
Remove the handling of OOB data from AF_LOCAL domain socket. Operation
related to OOB data will result in an error like Linux does.
(fhandler_socket_local::sendto): Ditto.
(fhandler_socket_local::sendmsg): Ditto.
This fixes the issue reported in following post.

Commit ebd645e on 2001-10-03 made environ.cc:_addenv() add unneeded
space at the end of the environment block to "work around problems
with some buggy applications." This clutters the code and is
presumably no longer needed.
Thanks to Ken Harris <Ken.Harris@mathworks.com> for the diagnosis.
When backing up tail to handle a "..", the code only checked that
it didn't underrun the destination buffer while removing path
components. It did *not* take into account that the first backslash
in the path had to be kept intact. Example path to trigger the
problem: "C:\A..\..\..\B'
Fix this by moving the dst pointer to the first backslash so subsequent
tests cannot underrun this position. Also make sure that we always
*have* a backslash.

which led to a buffer underrun in this loop.

GCC 7 is able to see straight through this trick, so use a more formal
method to avoid the warning.

There are systems with a MaximumProcessorCount not
reflecting the actually available CPUs. The ActiveProcessorCount
is correct though. So we use ActiveProcessorCount rather than
MaximumProcessorCount per group to set group affinity correctly.

* 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

We need to share socket info between threads *and* processes.
SRWLOCKs are single-process only, unfortunately. Provide a
sharable low-profile spinlock instead.

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.
