FreeBSD keeps every character device on devfs, whose devfs_statfs reports
512-byte blocks, 2 blocks and nothing free. Windows threw for any console,
NUL or the guest random device, and Linux described the host's /dev mount.
A kqueue now returns EINVAL, as getvnode does.

sosend_generic fails a send on a socket that can send no more with EPIPE
before it looks at so_error. Winsock reports the same send as WSAECONNABORTED
or WSAECONNRESET, which reached the guest as ECONNABORTED or ECONNRESET.
A stream send now maps both to EPIPE. The send-after-close checks of
guest_tcp, guest_socket_read_write and guest_socket_pair run on Windows too.

A null or uninitialized attribute, and a kind outside 1 to 4, threw
std::invalid_argument. They now go through NotImplemented_nid_no_patch,
as pthread_rwlockattr_settype_np's unmeasured types do. FreeBSD 11
libthr stores an unknown kind unchecked and answers a null attribute
with -1 and errno EINVAL, so scePthreadMutexattrSettype's
SCE_KERNEL_ERROR_EINVAL would match neither answer.
pthread_rwlockattr_settype_np stored any type and returned 0. The console's answer to a type outside 0 to 2 is unknown, and shadPS4 returns EINVAL once the stored type is above 2, so such a type now goes through NotImplemented_nid_no_patch. Types 0 to 2 are stored but not applied, so the debt entry moves to the silent stubs.
The SCE name moves from a libkernel_sys stub to libkernel. Kinds
MutexType::ErrorCheck (1) to MutexType::Adaptive (4) are the mutex
types FreeBSD 11 libthr's pthread_mutexattr_setkind_np stores, and are
set through scePthreadMutexattrSettype, which maps the same values onto
those types. Other kinds and a null or uninitialized attribute throw, as
their console answer is not known.
guest_kernel_sys_pthread_np_kind round-trips kinds 2, 3, 4 and 1
through pthread_mutexattr_gettype, checks that kind 1 makes a second
lock return EDEADLK and kind 2 lets it succeed, and checks the throws
for kinds 0, 5 and -1 (the type unchanged) and for a destroyed or null
attribute.
The POSIX name moves from a libkernel_sys stub to libkernel and stores the
type through its SCE twin scePthreadRwlockattrSettype, converting the
result as the other POSIX rwlock calls do.
guest_kernel_sys_pthread_np_rwlockattr checks types 0, 1 and 2 through
both names, a rwlock built from the attribute, and the throws for a
destroyed or null attribute.
soreceive_generic returns 0 for a socket whose receive side is shut and for a
zero-length receive on a connected stream socket (ENOTCONN when it is not
connected), without waiting. Winsock fails the first with WSAESHUTDOWN, which
reached the guest as EPIPE, and blocks the second until data arrives. recv and
recvfrom now answer both themselves.

On Linux sceKernelGetdirentries copied the host d_type, so a directory under app0 that is a host symlink was listed as a link, and a title that only descends into directory entries skipped it. Inside the app0 tree, report a symlink (or an entry of unknown type) as the type of its target; links elsewhere, and dangling links, stay links.
Both were missing from libkernel.prx, so a title importing either
(dYv-+If2GPk, RRnSj8h8VR4) failed to load. They take a relative timeout
in microseconds and are scePthreadRwlockTimedrdlock and
scePthreadRwlockTimedwrlock with POSIX error numbers; a zero lock is
initialized as by pthread_rwlock_rdlock. The signature comes from
shadPS4, which registers one function for each NID and its
scePthreadRwlockTimed* twin; FreeBSD 11.4 has no such calls. The throwing
libkernel_sys copies are removed, as an export may live in one library
only. Recorded in the libkernel debt file.

Follow FreeBSD 11.4 sys_setresuid and sys_setresgid (sys/kern/kern_prot.c):
accept real, effective, and saved user and group IDs for the guest process,
which is assumed to run as root with IDs 0. Setting an ID to 0 or -1 (unchanged)
is accepted without changing credentials and returns 0; any other value throws.
Cover both in guest_credentials test and update libkernel debt documentation.
On Windows a pair end now reports POLLIN after the peer's shutdown or close.
The console also reports POLLHUP after close; the loopback connection cannot
tell a close from a shutdown.

WSAPoll reports POLLHUP alone for a stream socket whose peer has closed, so
poll never returned POLLIN for it and a caller waiting for POLLIN did not see
the end of the stream. sopoll_generic reports a socket that can receive no
more as readable and adds POLLHUP only once it can send no more either.
poll now adds the requested read bit and keeps POLLHUP only after the socket
shut its own sending side. A reset or refused connection keeps WSAPoll's flags.

FreeBSD 11.4's sys_flock only requires a vnode descriptor, so flock on a directory descriptor succeeds. On Windows the call reached LockFileEx, which rejects a directory handle with ERROR_INVALID_PARAMETER, and flock_nid_postfix turned that into a runtime_error that aborted the process. A directory descriptor now returns 0 without taking a lock; the new guest_file_lock_directory case covers it and the debt entry records that no lock is held.
