_fpathconf_nid_postfix only treated FIFOs and sockets as descriptors without
a vnode, so a kqueue or shm_open descriptor fell through to the UFS constants
(LINK_MAX 32767, NAME_MAX 255, PIPE_BUF 512). FreeBSD 11.4 kern_fpathconf
(kern_descrip.c:1411-1429) answers _PC_ASYNC_IO for every descriptor and
returns EOPNOTSUPP for a no-vnode descriptor that is not a pipe or socket.
Return EOPNOTSUPP for kqueue and shared-memory descriptors.

Follow FreeBSD 11.4 sys_kenv: KENV_GET, KENV_SET, KENV_UNSET and KENV_DUMP over
an in-memory kernel environment of at most 512 variables, with the 128-byte
name and value limits, ENOENT, EINVAL, ENAMETOOLONG and EFAULT.

Follow FreeBSD 11.4's sys_kldsym: EFAULT for an unreadable lookup
structure, EINVAL for a wrong version or command, EFAULT or
ENAMETOOLONG for the symbol name, ENOENT for a negative file id. Any
other lookup throws, as no kernel module is modelled. Adds
GuestCopyIn_nid_no_patch for the checked structure read.

sigreturn applies FreeBSD 11's amd64 sys_sigreturn checks:
- EFAULT for a null context;
- EINVAL for unknown mc_flags, and for rflags bits outside
PSL_USERCHANGE that differ from the current flags;
- set_fpcontext's FPU format and ownership cases.
It then restores the context through the path setcontext uses, which
now lives in RestoreContext. A non-user %cs and an extended FPU state
still throw.
FreeBSD 11's sys_sched_setscheduler checks: a null parameter is EFAULT,
another process is ESRCH and an unknown policy is EINVAL. Pid 0 sets the
calling thread through scePthreadSetschedparam. Values that call
rejects, and the guest's own pid, whose first thread is not tracked,
still throw.
An owner or group other than the guest's (0) or the unchanged value
returns EPERM after the path lookup, as FreeBSD 11's chown(2) does for
a caller without the superuser privilege. That is the answer #8457
gives for fchown. A lookup error still comes first.
Replace the placeholder uuidgen_nid_postfix(void) declaration in
libkernel_sys/include/Api.hpp with the uuidgen(store, count) signature and
declare the GuestUuid layout there. Uuid.cpp and its test include the
public headers instead of declaring the functions and the type locally.
Generate version 1 UUIDs as FreeBSD 11's kern_uuidgen does: consecutive
timestamps from the guest CLOCK_REALTIME, a 14-bit clock sequence that is
randomised on first use and incremented when the clock has not passed the
last batch, and a random multicast node. A count outside 1 to 2048 fails
with EINVAL and a null store with EFAULT.
scePthreadCondInit ignores its name and nothing reads a condition variable name back, so pthread_cond_setname_np now only validates the condition variable and the name. Drops the stale libkernel_sys declaration and moves the debt entry to Silent stubs, citing shadPS4.

Store the name on the condition variable, creating a statically initialized one first, and return EINVAL for a destroyed one. A null cond or a null name throws, recorded in the libkernel debt file.

lchflags is chflags without following a symbolic link in the last path
component, as FreeBSD 11.4's sys_lchflags calls kern_chflagsat with
AT_SYMLINK_NOFOLLOW. chflags now goes through a shared helper that takes
the follow choice; a link in the last component is accepted as the
target when not following, and the flag checks are unchanged.
