Report the host IPv4 DNS servers of the interface sceNetCtlGetInfo
uses, through a helper libSceNetCtl exports, and return their count.
The signature and layout follow the OpenOrbis musl resolver and Net.h.

sceNetGetSockInfo returned 0 for a known socket and wrote nothing, so
callers read uninitialised bytes as the socket's endpoints. Monster
Hunter Wilds (PPSA24191) calls it after bind, connect and accept and
stores the local and remote address and port it reads back.
It now writes one 0xA0-byte record in the layout SharpProspero and
shadPS4 give: the socket id, the socket type, the local and remote
IPv4 address and port of the host socket in network byte order, the
SELF and NONBLOCK status flags, and the receive and send buffer sizes
sceNetGetsockopt reports for the socket. The other fields are 0. It
returns 1, the number of records written, and EINVAL for a null record
or an n below 1, as shadPS4 does.
An s below 0 lists the sockets as shadPS4 does: with a null record it
returns their number, otherwise it writes up to n records in socket
order and returns how many it wrote. Unlike shadPS4, which lists IPv6
sockets with zero addresses and ignores flags, an IPv6 socket fails
with EAFNOSUPPORT and is left out of the count and the list, and a
flags bit other than 0x40 fails with EINVAL. SharpProspero names 0x40
SockInfoTimeWait; closed sockets leave the table at once, so it lists
the same sockets. docs/dev/debt/libSceNet.md lists the fields left 0
and these differences.

Implement sceNetShowRoute as a silent stub returning 0, matching the (void) signature in shadPS4 and the behavior of sceNetShowIfconfig and sceNetShowNetstat. Adds guest unit tests in GuestSceNet.cpp and updates technical debt documentation.
sceNetSend, sceNetSendto, sceNetSendmsg, sceNetRecv, sceNetRecvfrom and
sceNetRecvmsg failed with EOPNOTSUPP for MSG_DONTWAIT on Windows, where
FreeBSD 11.4 sosend_generic and soreceive_generic make the one call
non-blocking and fail with EWOULDBLOCK when it would wait. Winsock has no
per-call flag, so the call now asks WSAPoll with a zero timeout whether the
socket is ready and fails with EAGAIN when it is not. The Windows branch of
the test that expected EOPNOTSUPP now runs the checks of the other hosts.

The overlap audit against origin/main and the open pull requests found 39 of
the 193 declared exports that must not be declared here:
- 14 that origin/main already exports. The nid_patcher computes the NID of a
symbol from its name, and a name ending in _nid_postfix exports the NID of
the base name, so scePadOpen, sceNetInit and the rest are already there.
- 23 that an open pull request provides: #6832, #6847, #6852, #7846, #7881,
#7889, #7890, #6977 and #7690.
- 2 whose technical-debt file an open pull request creates: #7463 and #8094.
The scope is now 30 libraries and 154 exports.
AnyPS5 resolves a title's imports by NID, so a title that imports a system
function no library provides fails to load with an unresolved import. The
PS5 3.20 export inventory lists 193 such exports across 37 PS5 system
libraries AnyPS5 implements but does not provide.
Declare them as throwing stubs so those titles load and reach their next
blocker. Each declaration calls NotImplemented_nid_no_patch and returns 0;
none of them implements the function. Declarations with a credible
prototype use it and cite the source with a pinned commit, and the rest
are declared without parameters, which resolves the import without making
an ABI claim. The technical-debt files record the limitation per library.
libSceMbus and libSceSystemService are left out because pull request #7821
declares them. libSceAgc is left out because its exports are versioned, so
the 3.20 NID names a different symbol from the one AnyPS5 ships.
libSceAvPlayer.native is left out because it compiles libSceAvPlayer's
Export.cpp.
Names and NIDs come from the PS5 3.20 export inventory at

On PS4 firmware 10.71 sceNetInetPtonEx reads IPv4 text the way
inet_aton does, not the way sceNetInetPton does: "1.2.3" is 1.2.0.3,
"127.1" is 127.0.0.1, hex and octal parts are accepted, a part value
wraps at 32 bits ("1.4294967296" is 1.0.0.0) and the text ends at the
first whitespace. Two differences from BSD inet_aton were measured: a
part starting with "09" is decimal ("0989" is 989), and an octal part
containing 8 or 9 fails.
The flags argument changed nothing for 0, every single bit up to
0x100, 0x10000, 0x80000000 and -1, so it is ignored instead of
throwing. IPv6 still converts as sceNetInetPton does, which matches
the console.

Implement sceNetGetIfName, sceNetGetRandom, sceNetMemoryAllocate and
sceNetMemoryFree with the signatures shadPS4 uses, and cover them in
guest_sce_net_tests.

PS4 firmware 10.71 converts "1.2.3.4" followed by a space, tab, LF,
VT, FF or CR, and anything after it ("1.2.3.4 x"), to 1.2.3.4 and
returns 1, where host inet_pton returns 0. Leading whitespace, other
trailing bytes (0x01, 0xa0), "1.2.3 " and IPv6 text with whitespace
still fail there.
A failed conversion leaves the destination and sceNetErrnoLoc
unchanged on the console; Winsock inet_pton writes the parsed prefix
before failing, so the conversion now goes through a local buffer.

sceNetUsleep fails with EINVAL for a negative count and otherwise sleeps
through libkernel's sceKernelUsleep, a cancellation point. sceNetInetPtonEx
converts as sceNetInetPton does when its flags are 0 and throws for any
other flags, whose meaning is unknown. The signatures follow shadPS4 and
are recorded as unverified in the libSceNet technical debt.
When the address came during the wait, the host receive that followed
waited its whole SO_RCVTIMEO again, so a receive could take up to twice
the timeout. FreeBSD's soreceive_dgram sleeps once per timeout. Now the
receive waits for a datagram with WSAPoll only for what is left of the
timeout, and fails with EAGAIN when it runs out, as before. Nothing
changes when the socket already had an address or has no timeout.
On Windows a receive on a datagram socket with no local address waits
for one. A sceNetShutdown of the receive side now ends that wait, and
later receives return 0 at once; a zero-length receive returns 0 without
waiting. FreeBSD's soreceive_dgram returns 0 in both cases. Before, a
thread blocked in such a receive kept waiting after the socket was shut
down.
sceNetConnect() on a connected datagram socket rejected an address
whose family is AF_UNSPEC (a null address) with EINVAL before touching
the socket, so the socket stayed connected: sceNetGetpeername() still
reported the old peer and datagrams from any other sender were dropped
by the host.
FreeBSD 11.4 disconnects a connected datagram socket first and only then
looks at the address. sys/kern/uipc_socket.c, soconnectat():
* If protocol is connection-based, can only connect once.
* Otherwise, if connected, try to disconnect first. This allows
* user to disconnect by connecting to, e.g., a null address.
*/
if (so->so_state & (SS_ISCONNECTED|SS_ISCONNECTING) &&
((so->so_proto->pr_flags & PR_CONNREQUIRED) ||
(error = sodisconnect(so)))) {
udp_disconnect() (sys/netinet/udp_usrreq.c) clears the peer and keeps
the local port. connect(2): "Datagram sockets may dissolve the
association by connecting to an invalid address, such as a null
address." libkernel's connect gets the same change in #4498.
A connected datagram socket given an address whose family byte is 0 is
now disconnected on the host first (AF_UNSPEC on Linux, a zeroed
address of the socket's family on Windows), and the call then fails
with EINVAL as before. Linux also drops an ephemeral local port on that
disconnect, so the port is bound again on the wildcard address, which
is what FreeBSD leaves. A host failure during the disconnect is
returned as the call's error. Stream sockets keep the previous path.

Resolve a host name to its first IPv6 address through the host resolver
(getaddrinfo with AF_INET6) and write the 16-byte address. The lookup
shares the IPv4 path's resolver bookkeeping (abort preservation, error
state); a name without an IPv6 address fails with RESOLVER_ENODNS like a
failed lookup. Nonzero flags throw.
Metal Gear Solid 4 Master Collection (PPSA18194) imports it and failed to
load without it (unresolved zl35YNs9jnI from libSceNet.prx).

FreeBSD's vfs_kqfilter checks neither the vnode type nor fflags, so the
registration is valid; it is only delivered for a move between directories,
which the Windows directory handle cannot tell from a removal plus an addition.
Also moves the TechnicalDebt entries to docs/dev/debt after main split the file.
