FreeBSD removes or renames a file that is still open; the descriptor stays usable. _wopen opens without FILE_SHARE_DELETE, so sceKernelUnlink returned EACCES and rename failed while the guest held a descriptor. sceKernelOpen now opens through CreateFileW with delete sharing and keeps the flag, mode and error mapping of _wopen.

SceErrorFromErrno in the libkernel file functions passed host errno
values 1-34 through and turned every other value into EIO. Linux numbers
EAGAIN 11, which is FreeBSD's EDEADLK, so a read from an empty
non-blocking pipe returned SCE_KERNEL_ERROR_EDEADLK, and ENAMETOOLONG,
ELOOP, ENOTEMPTY, EDQUOT and EOVERFLOW, whose host values differ from
FreeBSD's, all became EIO.
Map those host values to the guest's FreeBSD numbers, as
SceIoErrorFromErrno in Open.cpp already does for EAGAIN, EDEADLK,
EDQUOT and EOVERFLOW. The guest constants the callers pass are all at
most 34 and never 11, or GUEST_ENOTEMPTY, so they are unchanged.

FreeBSD's fsync and fdatasync succeed on a descriptor opened read-only and on a directory. _commit needs write access, so both returned EBADF there. A read-only descriptor is now flushed through a write handle from ReOpenFile and a directory through a handle opened for it, as sceKernelSync already does.
lseek on a non-directory descriptor no longer takes the directory table lock when no directory is open, and a listing is read under the descriptor's own lock. SEEK_CUR with offset 0 only reports the position, and an overflowing SEEK_CUR offset reports EOVERFLOW.
FreeBSD fchdir(2) changes the working directory to the directory referenced by a descriptor. The guest imports fchdir from libkernel_sys (PPSA99764, issue #1578) and the module did not export it.
The descriptor's directory is resolved from the path recorded when the directory was opened on Windows, and from the /proc/self/fd link target on Linux. The guest working directory is then set through the libc routine shared with chdir. A descriptor that is not open returns EBADF and one that is not a directory returns ENOTDIR.
AI-assisted: yes

`truncate` (`ayrtszI7GBg`) is an absent import of PS5MC (PPSA99420),
XPSemu (PPSA97358) and Porpoise (PPSA99764) on `main`. It resolves
through `sceKernelTruncate`, which now returns `EISDIR` for a directory
and the host errno for other failures instead of `EIO`, as FreeBSD 11
`kern_truncate` does. The guest-relative test `guest_truncate` covers
shrinking, growing with zero fill, a negative length, a missing path,
an empty path, a null path, a directory and a read-only file.

Capture errno before the ENOTDIR lookup, translate EINVAL from a name
under a regular file to ENOTDIR, check the parent only once and strip a
trailing separator before taking it, and split the dense rmdir return.
On Windows mkdir_nid_postfix returned ENOENT and sceKernelMkdir and
sceKernelRmdir returned ENOENT or EIO when a regular file was used as a
directory in the path. FreeBSD mkdir(2) and rmdir(2) return ENOTDIR for
a path component that is not a directory.
FreeBSD's unlink ignores the file's own permission bits, so it succeeds
on a file the guest made read-only with chmod(0400). On Windows the guest
chmod sets the read-only attribute and _wunlink then failed with EACCES,
which sceKernelUnlink and unlink reported. When the path is a regular file
without write permission, make it writable before the single _wunlink and
restore the read-only attribute if the unlink fails, as remove() does
since #2342.

A guest path whose bytes the host cannot convert to a native path made
ResolvePath throw std::filesystem::filesystem_error, which aborted the
process. No file can have such a name on the host, so stat reports
ENOENT, as for any other missing file.
