Human Fall Flat (PPSA02429) opens its sockets with libkernel's socket()
and registers them with sceNetEpollControl. libSceNet only looked in its
own socket table, so every ADD and DEL failed with SCE_NET_ERROR_EBADF.
The game retries without pause: on box 2 it made more than 1.6 million
failing calls on 14 descriptors in its first seconds, all of them
libkernel sockets.
sceNetEpollControl now accepts a descriptor libkernel has open as a
socket, as sceNetSocketClose and sceNetSetsockopt already do for MXGP 26
(PPSA30839). sceNetEpollWait looks up the host socket of such a
registration through libkernel after g_mutex is released, because that
lookup asks libSceNet's own table for descriptors libkernel does not
own, and keeps the owner alive across the host poll. libkernel's close()
retires the registrations of the closed socket; a wait drops a
registration whose socket is gone.
guest_sce_net registers a libkernel UDP socket, waits for it to become
readable and then writable, deletes it twice, closes registered sockets
through close() and sceKernelClose and waits again, and checks that a
descriptor that was never open still fails with EBADF.
The libc.prx bundled with PPSA02530 keeps error_code values in the second
dword: the shared error_category::default_error_condition shifts the value
into the high half and the equivalent overloads compare that dword and the
category. Export the type info, the base destructor and the three base
members, so titles that import them resolve to the same code the generic
and system category vtables already use.
future_category returns a static _Future_error_category derived from
_Generic_error_category and named "future". Its message maps 1..4 to
"broken promise", "future already retrieved", "promise already satisfied"
and "no state", and falls back to the generic table. future_error is 0x40
bytes: a GuestLocale::String at 0x8 and the 16-byte error_code at 0x30; its
0x30-byte vtable carries the console's _Doraise slot. _Throw_future_error
allocates that size and throws it with the console type info, and
_Rethrow_future_exception delegates to rethrow_exception.
The recorder released its lock between recording a submission, flip or
suspend point and the driver accepting it. Another thread's delta could
then wait for the accepted work, read its blocks, and record itself
after a call whose work the driver had not accepted yet, so the replay
submitted that work before applying stale bytes over its result. The
entry points now pass the driver call to the recorder, which runs it
under the same lock right after recording the call.
agc_driver_frame_replay_concurrent submits copies from a second thread
during the capture and checks that every memory delta was read after
the submissions recorded before it had completed.

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.

swscanf restores errno around strtof and strtod, as the bundled
libc.prx does, while long double conversions keep host strtold's
errno and the narrow sscanf family keeps the host's ERANGE. Record
both gaps in the existing swscanf debt entry, as review asked.

The PS5 module read for #9027 returns 0x80268006 from sceAudioOut2MasteringInit,
sceAudioOut2MasteringInitEx, sceAudioOut2MasteringTerm,
sceAudioOut2MasteringGetState and sceAudioOut2MasteringSetParam before
sceAudioOut2Initialize. #9027 left the check out because AudioOut2
initialization was not tracked; AudioOut2IsInitialized_nid_no_patch now
tracks it, so each of these returns 0x80268006 first, before its own
mastering-state and argument checks, and changes no state. The debt entry
drops the closed gap.

atan2f returned the host atan2, so its last bit depended on the host: on
Windows it differs from the libc.prx that titles ship on 7,126,466 of
200,001,024 sampled argument pairs. That libc.prx is msun's e_atan2f.c over
its atanf; with two NaN arguments it returns y's. The port gives the same
bits as PPSA07923's, PPSA05916's and PPSA13934's copies on every pair.

Main implements sceAppContentGetEntitlementKey next to this branch's
sceAppContentGetPftFlag; the merge keeps both declarations, both test
blocks and both debt entries. With that export implemented, Export.cpp
has 8 NotImplemented exports, and the pending-exports count says 8.
Read the unwind functions of an image that only has PT_GNU_EH_FRAME so
inter-FDE data tables are still found and masked, but leave the syscall
and call-site scan ranges empty without PT_SCE_DYNLIBDATA as main does.
The fixture now emits standard dynamic tags for its SysV block, and the
debt entry stays within the 1000 character limit.
