2b745ad9f6 smbd: recursive delay_for_handle_lease_break_send()
Check for open files recursively when renaming a directory and wait for handle
lease breaks.

As delay_for_handle_lease_break_send() does the same check as
have_file_open_below(), remove have_file_open_below() from can_rename() so it is
not called twice for SMB2 renames, and add calls to have_file_open_below() to the
SMB1 entry rename entry points.

This is a bit ugly, but I don't see any other good way of doing this.

03fe0d631d smbd: Simplify unix_perms_from_wire()
Remove enum perm_type: Only the _NEW_ defines were actually used, and
this made the logic harder for me to understand than necessary.

On the other hand, it forced you to think about what this is. Now you
could theoretically miss applying masks. Still, I like it better with
this patch.

61d9c0d92e smbd: add options "fs:[logical|aligned|performance|effective aligned] bytes per sector"
In order to support certain Windows applications that make use of copy reflink,
we need some way to allow configuring these values. According to testing, the
application somehow uses the value of phys_bytes_per_sector_atomic for some check
when requesting server-side reflink copies, eg for ZFS the following is needed

 block size = 131072
 fs:aligned bytes per sector = 131072

For some reason "block size" must also be set to the value of fs:aligned bytes
per sector, but fs:logical bytes per sector, which according to the spec should
match "block size", must stay at the default of 512, otherwise the application
does not work.

As the whole client behaviour could not be fully understood, I'm proposing to
introduce these options as undocumented parametric options, so we can at least
start testing with them.

deeca8ff17 smbd: consolidate fs capabilities code in vfswrap_fs_capabilities()
This ensures the values we return via SMB_FS_ATTRIBUTE_INFORMATION is the same
we use internally via conn->fs_capabilities.

This deliberately preserves existing behaviour as much as possible and leaves
possible improvements as a future excercize. Particularily FILE_VOLUME_QUOTAS is
already set insided SMB_VFS_STATVFS() depending on backend filesystem flags
which is probably the correct way to do it instead of just setting the
capability when Samba was built with quota support.

bf497819e6 smbd: fix check_any_access_fsp() for non-fsa fsps
smbd_check_access_rights_fsp() requires *all* rights in access_mask to
be granted by the underlying ACL, but the semantics of this function
is supposed to grant access if any one of the rights in
access_requested is allowed.

Fix this by looping over the requested access mask. If
smbd_check_access_rights_fsp() returns sucess, mask will be non-null
and when assigned to access_granted, the subsequent check will pass,
fail otherwise.

I'm not doing an early exit on purpose because a subsequent commit
adds additional security checks that are done in the subsequent code
path common for fsa and non-fsa fsps.
