c2ac923c6a s3: safe_string: do not include string_wrappers.h
Rather than have safe_string.h #include string_wrappers.h, make users of
string_wrappers.h include it explicitly.

includes.h now no longer includes string_wrappers.h transitively. Still
allow includes.h to #include safe_string.h for now so that as many
modules as possible get the safety checks in it.

Add search request size limits to ldap_decode calls.

The ldap server uses the smb.conf variable
"ldap max search request size" which defaults to 250Kb.
For cldap the limit is hard coded as 4096.

4d4443d1e5 loadparm: check for AD DC required VFS modules
When Samba is running as a domain controller and the "vfs objects"
parameter is not set, then the dfs_samba4 and acl_xattr modules are
automatically enabled.
However, if the "vfs objects" is defined, then the setting is left
as-is. This means that attempts to us other VFS modules have the side
effect of disabling the dfs_samba4 and acl_xattr modules, causing
unexpected behaviour, which is then blamed on the VFS modules that were
explicitly defined.

This change ensures that when running as a domain controller, Samba logs
an error if the required VFS modules are not enabled by an explicit
"vfs objects" definition.

063c4b25b1 s3:param: split out loadparm_s3_global_substitution from lp_string()
The idea is to get rid of the global state that's
currently used for the substitution in lp_string().

In the end all callers need to pass an explicit
const struct loadparm_substitution *sub_ctx,
which contains all relevant information
for the substitution. At that point lp_string() can be removed.

For now we provide loadparm_s3_global_substitution()
for callers to keep the current bahavior unchanged.

0fa490e847 s3:loadparm: Ensure to truncate FS Volume Label at multibyte boundary
For FS_VOLUME_INFO/FS_INFO operation, a maximum of 32 characters are
sent back. However, since Samba chops off any share name with >32
bytes at 32, it is possible that a multi-byte share name can get chopped
off between a full character. This causes the string decoding for unicode
failure which sends back NT_STATUS_ILLEGAL_CHARACTER (EILSEQ) to the client
applications.

On Windows, Notepad doesn't like it, and refuses to open a file in this
case and fails with the following error:

  Invalid character. For multibyte character sets, only the leading byte is
  included without the trailing byte. For Unicode character sets, include
  the characters 0xFFFF and 0xFFFE.

Proposed fix:
- Find the last starting point of a multibyte codepoint if the character
  at 32nd byte is a subsequent byte of a MB codepoint.
