mazen320 mapped the relocated slots of KfcTPbeaOqg in the console's
libSceLibcInternal: offset-to-top, typeinfo, the two destructors,
locale::facet::_Incref and _Decref, and the eleven do_get. The debt
entry now says so instead of leaving the two extra entries unknown.

mazen320 read KfcTPbeaOqg from the console's libSceLibcInternal.sprx
symbol table: an object of 136 bytes, 17 pointer slots. Export that
size instead of the 15 derived from Dinkumware's crt.vc12 xlocnum, and
say in the debt entry that which two virtual functions are added is
not known.

Resolves the conflict with #8867 in EntryStubTests.cpp: keep its two
kernel-variant tests and the BufferUtils include, and this branch's
libSceAmpr-to-libc fallback test, with all three called from main.

FreeBSD 11 fopen opens the path with _open, and vn_open_vnode refuses a
directory only for FWRITE or O_TRUNC, so fopen of a directory in a read
mode succeeds; Linux hosts already open it. On Windows CreateFileW
without FILE_FLAG_BACKUP_SEMANTICS refused it with EACCES.
fopen now opens such a path as a libkernel directory descriptor, which
libkernel registers in libc when it loads, and fclose and freopen remove
it from libkernel's table. Reads on the stream fail with EISDIR and set
the error indicator, as on a Linux host and FreeBSD's tmpfs: the Windows
CRT fails them already but reports EINVAL. Writes fail with EBADF, and
fseek, ftell and ungetc work, as on any read-only stream.
The public SDK's libSceLibcInternal table declares num_get<char>::id, time_get<char>::id and the
num_get<char> vtable as objects; libSceAmpr exported their NIDs as functions that throw, which a
data consumer reads as code (#8875). libc now defines them the way the other facet ids and the
num_put and codecvt vtables are kept: the ids zero, the vtable 15 zeroed slots (two header
entries, the two destructor entries and Dinkumware's eleven do_get), and libSceAmpr drops the
functions. An import qualified to libSceAmpr.prx falls back to libc, so each object has one
identity.

Kernel and native-library writes into guest pages the write watch left read-only fail with EFAULT on macOS and ERROR_NOACCESS on Windows (#7473). State the rule where contributors look and point the macOS write-watch debt entry at it.
The crash and abort reports printed the last 64 traced calls of the whole
process, so a thread that loops on a traced import (a mutex lock/unlock
pair, a profiler marker) pushes the calls of the faulting thread out of the
report. The ring already keeps the last 65536 calls with their thread.
CopyThreadCallTrace_nid_no_patch returns the most recent calls of one
thread from that ring, oldest first, and both reports (Windows crash and
abort, Linux abort) list up to 32 of them for the reporting thread after
the process-wide list.

On Windows, freopen reopened a stream through _wfreopen, which opens the file without FILE_SHARE_DELETE, so remove or rename of the file failed while the stream was open, unlike fopen streams and POSIX unlink/rename of an open file. freopen now closes the previous stream and opens the new file through the same CreateFileW path fopen uses, so the reopened stream shares delete access. Host standard streams and an empty filename keep the _wfreopen path. Reference: FreeBSD 11 unlink(2) and rename(2) succeed on a file that is open.
Animal Well (PPSA22520) imports _Thrd_detach (L7f7zYwBvZA) from libc.prx and nothing exports it, so the Windows loader stops at startup. Register libkernel's pthread_detach with libc like pthread_create and pthread_join, and return _Thrd_error (4) when it fails.
