feat(libSceLibcInternal): export sys_siglist and sys_nsig
PS5CEMU-HAR (PPSA99360, ps5-payload-dev build, relinks with --trap-sdk-syscall-stubs) imports the data objects sys_siglist (yCdGspbNHZ8) and sys_nsig (ZD+Dp+-LsGg) from libSceLibcInternal.prx; the import audit lists both as absent (registry entries 364 and 378, after pthread_setaffinity_np at 276). No run has reached them yet; the predicted stop line is FAIL: unresolved ELF import ZD+Dp+-LsGg (sys_nsig) from libSceLibcInternal.prx or yCdGspbNHZ8 (sys_siglist), whichever the loader resolves first. The table and count are FreeBSD 11.4 lib/libc/gen/siglist.c (8c639945): 32 descriptions, signal 0 to SIGUSR2 (NSIG 32), and sys_nsig is their number, 32. ps5-payload-dev declares both as objects exported by libSceLibcInternal and its strsignal reads them.

- [Thread exit destructors](../../../core/libs/prx/libSceLibcInternal/Export.cpp) (libSceLibcInternal) run when a libkernel thread finishes; on the main or a host thread only `_sceLibcInternalThreadDtors` runs them, as `exit` does, else they are dropped
|
||||
- [fdopendir](../../../core/libs/prx/libSceLibcInternal/Directory.cpp) (libSceLibcInternal) - the directory stream starts at the directory's first entry, while FreeBSD's [`fdopendir`](https://github.com/freebsd/freebsd-src/blob/release/11.0.0/lib/libc/gen/opendir.c#L67-L74) reads from the descriptor's current offset, and `FD_CLOEXEC` is not set on the descriptor. As in FreeBSD, a descriptor that is not open fails with `EBADF`, one that is not a directory with `ENOTDIR` (both leave it open), and `closedir` closes it
|
||||
- [fstatvfs](../../../core/libs/prx/libSceLibcInternal/FilesystemStatistics.cpp) (libSceLibcInternal) converts `_fstatfs` to the 88-byte `struct statvfs` as FreeBSD 9.2's `sfs2svfs` does (`f_bsize` from the transfer size, `f_frsize` from the block size, `f_favail` equal to `f_ffree`, `f_fsid` 0, `ST_RDONLY` and `ST_NOSUID` only). Differences: `f_namemax` is the `statfs` value, not `fpathconf(_PC_NAME_MAX)`; negative `f_bavail` and `f_ffree` wrap to unsigned without `EOVERFLOW`, as the same-width copy in FreeBSD does; inode counts are 0 on Windows, inherited from `_fstatfs`; a null output returns `EFAULT` after the descriptor is validated, where FreeBSD would fault. Layout and conversion are unverified against the PS5 library (PS5MC imports `fstatvfs` but was not run)
|
||||
- [sys_siglist and sys_nsig](../../../core/libs/prx/libSceLibcInternal/SignalList.cpp) (libSceLibcInternal) hold the 32 descriptions and the count of [FreeBSD 11.4](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/gen/siglist.c#L73-L107) `siglist.c` (`NSIG` 32, signal 0 to `SIGUSR2`); the console's table was not read
|
||||
- [posix_spawn and posix_spawnp](../../../core/libs/prx/libSceLibcInternal/Spawn.cpp) (libSceLibcInternal) throw: creating a child process is not supported. PPSA99305 (Dusklight) and PPSA99309 (Wind Waker) stop on `main` at unresolved import `44hlATrd47U` (`posix_spawnattr_init`); a run with this PR has not established how far either title gets, and process creation still throws. The attribute and file action calls keep FreeBSD 11.4's objects, so a real `posix_spawn` would have to apply them in the child. Null or uninitialized objects, which FreeBSD dereferences, throw.
|
||||
- [getopt, getopt_long](../../../core/libs/prx/libSceLibcInternal/Getopt.cpp) (libSceLibcInternal) follow FreeBSD 11 [getopt.c](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/stdlib/getopt.c) and [getopt_long.c](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/stdlib/getopt_long.c) with `GNU_COMPATIBLE`: `getopt` does not permute, `getopt_long` permutes unless `POSIXLY_CORRECT` is set in the guest environment or the option string starts with `+`, and the exported `opterr`, `optind`, `optopt`, `optreset` and `optarg` start at 1, 1, 0, 0 and null. Warnings go to the guest's current `stderr` prefixed with `__progname`, where FreeBSD's `warnx` keeps the `stderr` of its first call. A null `getopt` option string, a null argument vector or argument, a negative `optind` and an `optind` moved inside a pending permutation throw where FreeBSD faults. `getopt_long_only` is not exported. That the console's `libSceLibcInternal` uses this FreeBSD code is unverified
