msync follows FreeBSD 11's kern_msync and vm_map_sync over the guest's
mappings as sceKernelVirtualQuery reports them: the address is rounded
down to the page, a range that wraps and MS_ASYNC with MS_INVALIDATE are
EINVAL, an unmapped start or page is ENOMEM, and length 0 checks the
mapping that holds the address. The guest has no file mappings, so a
successful call has nothing to write back. MS_INVALIDATE on a mapped
range throws, since FreeBSD's EBUSY for mlocked pages needs lock state
that is not tracked.
EVO-PLAYER PPSA99039 v0.11.0 imports it.

A title's descriptors are taken as never being terminals: a file or
pipe gets ENOTTY with the termios untouched, a socket gets what its
protocol answers a termios ioctl on FreeBSD (EADDRNOTAVAIL for AF_INET,
EOPNOTSUPP otherwise), and a closed or invalid descriptor EBADF.
tcsetattr gives EINVAL for an action other than TCSANOW, TCSADRAIN or
TCSAFLUSH, with or without TCSASOFT, before anything else, and EFAULT
for a null termios before the descriptor is checked; with TCSASOFT a
null termios throws, where FreeBSD's libc faults copying it. What the
console gives a title as descriptors 0 to 2 is unknown, as recorded in
TechnicalDebt.

The guest process is assumed to run as root. Under FreeBSD's
sys_seteuid and sys_setegid, id 0 is then accepted without a privilege
check and changes no credential, so both return 0. Any other id would
change the effective credential, which is not modelled, and throws.
Part of #1578.
sceKernelMunlock and the POSIX munlock unlock the page-rounded range with
FreeBSD's results: 0 for a mapped range whether or not it is locked, EINVAL
for a range that wraps around zero, ENOMEM for an unmapped range. On Linux
the host munlock gives them. On Windows a reserved placeholder counts as
mapped only while the guest reservation or protection registry covers it,
and a region VirtualUnlock refuses as not fully locked is unlocked page by
page, as VirtualUnlock is all-or-nothing. sceKernelMlock shares the range
rounding.

The POSIX form of sceKernelMlock: 0 on success, -1 with errno (EINVAL,
ENOMEM, EPERM, EAGAIN) where the sce form returns the kernel error, as
munmap and mprotect do beside it.

The repo allows one implementation per export. Move libc's rename into
libc/src/Rename.cpp, compile that file into both libc and libkernel, and
drop the second copy from libkernel's Stdio.cpp. FilesystemError moves to a
header so the shared source can use it.
The test now checks that the symbol it resolves belongs to libkernel (module
handle on Windows, dladdr on Linux) so it fails when the export is removed.

guest_filesystem_tests links libkernel and libc, both of which define
rename_nid_postfix, so which one it binds to depends on the loader and the
suite passes either way. Resolve the symbol from libkernel.prx explicitly so
the export added for titles that ship their own libc.prx is actually tested.

Titles that ship their own libc in sce_module import rename from
libkernel (NID NN01qLRhiqU), where it was missing, so PPSA12544 failed
to start. It checks both paths like unlink and maps sceKernelRename's
result to errno.

AF_UNIX pairs as FreeBSD 11 makes them: SOCK_STREAM, SOCK_DGRAM and
SOCK_SEQPACKET with protocol 0, SOCK_NONBLOCK applied to both ends and
SOCK_CLOEXEC accepted, EAFNOSUPPORT for an unknown family, EOPNOTSUPP
for AF_INET and AF_INET6, EPROTONOSUPPORT for type 0 or a protocol,
EPROTOTYPE for another type, EFAULT for a null output, and nothing
written on failure. The ends are guest sockets, so send, recv,
shutdown, fcntl, poll and close work on them; getsockname and
getpeername report the unnamed AF_UNIX address, recvfrom and recvmsg
no address for a stream and the unnamed one for a datagram. On Linux
the pair is the host's socketpair; on Windows a loopback TCP connection
or two connected UDP sockets, and SOCK_SEQPACKET throws. The remaining
differences from the console are recorded in TechnicalDebt.
OpenSSL's QUIC notifier in 15 catalog titles creates such a pair.

Returns the name of the directory under which a title's sandbox exposes
system files, which homebrew SDKs splice into paths such as
/<name>/common/cert/CA_LIST.cer and /<name>/common/lib/libc.sprx. The
name is fixed here; recorded in TechnicalDebt together with the fact
that nothing is mounted under it.
Registers guest_sandbox_random_word.

Hades (PPSA03355) stops at load on main with "undefined symbol:
9HzfhdtESio", the NID of pthread_getname_np, which it calls on
pthread_self() with a 32-byte buffer. Measured on a PS5 (firmware 13.60)
through dlopen of libkernel: the function takes (thread, buffer), copies
the name and its terminator, returns an empty name for an unnamed
thread, ESRCH for a null or joined thread and EFAULT for a null buffer.

ScreenTester5 (PPSA69420) stops at start-up on the unresolved sysctlbyname
import and also imports sysctl. hw.ncpu (CTL_HW.HW_NCPU) reports the same
processor count as sysconf(_SC_NPROCESSORS_ONLN). Other names and MIBs throw.
Add sigemptyset, sigfillset, sigaddset, sigdelset and sigismember with
FreeBSD 11 semantics (lib/libc/gen/sigsetops.c): a 128-bit set of four
32-bit words, signal n at bit n - 1, signals 1 to 128 valid. sigfillset
sets every bit. An invalid signal returns -1 with errno EINVAL and leaves
the set untouched; sigismember returns 1 or 0. A null set throws.
