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.
A delta read its blocks with ReadCommittedUnsynced while GPU work
accepted before the call could still write them, so a capture could
hold a block from before a DMA copy that the replay then wrote back over
the copy's result. A delta with blocks to read now waits up to 10 s for
the accepted submissions and records the serials after the wait; the
capture stops with a warning when the work does not finish. The Windows
quarantine of agc_driver_frame_replay is removed.

In PS5 Prospero PRX binaries, compilers place embedded constant data tables (such as the OpenSSL Whirlpool lookup table in ubiservices.prx) in inter-FDE gaps after function code, referenced via RIP-relative LEA instructions.
- In RelativeJumpTables, detect constant data tables in inter-FDE gaps that begin with padding, contain no direct branch targets, and contain undecodable non-code bytes, distinguishing them from valid unannotated code routines and multi-hop gap branches.
- In GuestModuleBuilder and RelinkerPipeline, extract unwind functions from PT_GNU_EH_FRAME as well as PT_SCE_DYNLIBDATA, and mask embedded data tables with 0x90 in scan buffers before SyscallScanner.
- In CodeInstructionCollector, populate table boundaries whenever unwind functions are present to prevent addAddressTakenRoot from adding data table addresses to CFG roots on Windows and macOS.
- Update relinker technical debt documentation and add regression tests.

BunnyFl ran firmware 13.42's libSceSystemService.sprx in an emulator and
recorded the checks these calls make before they pass a request on. A
null title ID or one whose length isn't 9 makes sceSystemServiceGetAppId
and sceLncUtilGetAppId return -1 and sceLncUtilIsAppLaunched return
0x80940005. A null output, list, count or user returns 0x80940005 from
the LncUtil and SystemService calls and 0x80e30003 from
sceShellCoreUtilGetUserFocus, before the app ID is looked at, and a null
sceLncUtilLoadExec path returns 0x80940005.
What the module passes on as a request still throws: another
9-character title ID, another app ID, a list capacity of 0 and an empty
sceLncUtilLoadExec path.
On a standard-port handle the console answers NOT_PERMITTED (0x80920101):
Halo CE Universal's pad probe measured it on firmware 13.59 for two
connected DualSenses in three runs. The function returned 0 with
invented controller information instead. The special port keeps its
zeroed answer.

The libc.prx that PPSA31872 ships returns ERANGE for a buffer shorter than
23 bytes and otherwise strncpy's length - 1 bytes and terminates the last
one. This matches the firmware 13.60 log, where error 0 with a 16-byte
buffer returned 34 although "No error" fits.

Prospero Win measured on firmware 12.02 that the PS5 kernel accepts
MAP_EXCL but ignores it: MAP_FIXED | MAP_EXCL over an existing mapping
replaces it without error. Fixed anonymous mmap now does the same instead
of FreeBSD's ENOMEM. MAP_EXCL without MAP_FIXED stays EINVAL.

The nine-slot _ZTVSt7collateIcE export added by #9979 was still zeroed, so a guest that called through the exported vtable faulted. Fill slots 2 through 8 with the same facet methods that g_collateVtable uses, leave the offset-to-top and typeinfo slots zero, and cover compare, transform, hash, retain and release through the exported object.
