FreeBSD 11.4's lookup() (sys/kern/vfs_lookup.c) fails with ENOTDIR when
a path with a trailing slash ends at something that is not a directory.
On Windows a mount alias dropped the slash, and the host calls do not
report ENOTDIR for "file\", so unlink, rename and open acted on the file
or failed with EINVAL. Guest path resolution now rejects an existing
non-directory named with a trailing slash with ENOTDIR on every host, and
a mount alias keeps the slash on Windows as it does on Linux and macOS.
The trap checks unmask exceptions with feenableexcept and its relatives
and expect MXCSR to hold the new masks, and the enable and disable
results to report the traps enabled on both units. Under Rosetta 2
MXCSR keeps its six exception masks set, so no SSE trap is ever enabled
and every result reports none. The test now asks the host once whether
it keeps an unmasked MXCSR exception and, where it does not, expects
all six SSE masks set and no trap on both units; on other hosts the
expectations are the same as before. A debt entry records that the
trap functions change only the x87 masks under Rosetta.
Under Rosetta 2 the six MXCSR exception masks always read back set: a
write that unmasks an SSE exception is not kept, while the x87 masks and
the other MXCSR bits are. guest_floating_point unmasked the overflow
exception on both units and then expected MXCSR to equal the value it
wrote, so it failed on macOS although fesetexceptflag and feclearexcept
left the masks alone. The test now compares with the environment read
back after the write, which on other hosts is the value written. The
debt entry for the floating-point functions notes the Rosetta behaviour.
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.

wcstombs_s ends without error when a character does not fit a limit
below the capacity, as the console's does; wcsrtombs_s still reports
ERANGE there. Both paths became reachable with UTF-8. wcsftime keeps
returning 0 for a null buffer, and the debt entries that described the
single-byte locale now describe the UTF-8 one.

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.
