Novell NCOPY can allocate temporary directory handles while checking
effective directory rights before copying. On long-running test runs the
temporary directory handle table may already contain stale entries, causing
Allocate Temporary Directory Handle to fail with -0x9d / "no directory
handles". NCOPY then falls back to relative GetEffectiveRights requests that
fail and reports:
NWGetEffectiveDirectoryRights returned an error.
Restore recycling of stale temporary directory handles in xinsert_new_dir().
Free slots are still preferred. If none are available and the caller requests
a temporary handle, recycle the oldest temporary handle for the same task first,
then the oldest temporary handle globally. Permanent directory handles are not
recycled.
This matches the expected NetWare-style behaviour for temporary handles and
allows NCOPY-style allocate-temp-handle / get-effective-rights flows to keep
working after repeated tests.
Apply the ignore-case volume option when preparing the SYS:LOGIN
directory path during connection setup.
With SYS configured as `itO`, the installed tree may use lowercase
Unix directories such as `login/`, but the connection code still tried
to stat the hard-coded uppercase `LOGIN/` path. This caused new client
connections to abort with:
Stat error LOGIN Directory, Abort !!: No such file or directory
UnixPath=`.../SYS/LOGIN/`
Treat `VOL_OPTION_IGNCASE` like `VOL_OPTION_DOWNSHIFT` for this path so
the login directory is resolved as `login/` on ignore-case volumes.
