* Remove "unknown" from dfs_Enum (samba4 dfs IDL updates to follow).
* When encountering an unsupported infolevel the rpc server must reply
with a dfs_info_0 structure and WERR_OK (observed from w2k3 when talking
to nt4).

netbios aliases. Reported by Björn Jacke <bjoern@j3e.de>.
Probably needs to be in 3.0.23b (if Björn approves
of the fix).

fact that check_path_syntax() will convert '\\' characters to '/'.
When POSIX pathnames have been selected this doesn't happen, so we
must look for the unaltered separator of '\\' instead of the modified '/'.
Stevef please check this with the CIFSFS MS-DFS code !

we're using -1 as a special size_t case by casting.

realloc can return NULL in one of two cases - (1) the realloc failed,
(2) realloc succeeded but the new size requested was zero, in which
case this is identical to a free() call.
The error paths dealing with these two cases should be different,
but mostly weren't. Secondly the standard idiom for dealing with
realloc when you know the new size is non-zero is the following :
tmp = realloc(p, size);
if (!tmp) {
SAFE_FREE(p);
return error;
} else {
p = tmp;
}
However, there were *many* *many* places in Samba where we were
using the old (broken) idiom of :
p = realloc(p, size)
if (!p) {
return error;
}
which will leak the memory pointed to by p on realloc fail.
This commit (hopefully) fixes all these cases by moving to
a standard idiom of :
p = SMB_REALLOC(p, size)
if (!p) {
return error;
}
Where if the realloc returns null due to the realloc failing
or size == 0 we *guarentee* that the storage pointed to by p
has been freed. This allows me to remove a lot of code that
was dealing with the standard (more verbose) method that required
a tmp pointer. This is almost always what you want. When a
realloc fails you never usually want the old memory, you
want to free it and get into your error processing asap.
For the 11 remaining cases where we really do need to keep the
old pointer I have invented the new macro SMB_REALLOC_KEEP_OLD_ON_ERROR,
which can be used as follows :
tmp = SMB_REALLOC_KEEP_OLD_ON_ERROR(p, size);
if (!tmp) {
SAFE_FREE(p);
return error;
} else {
p = tmp;
}
SMB_REALLOC_KEEP_OLD_ON_ERROR guarentees never to free the
pointer p, even on size == 0 or realloc fail. All this is
done by a hidden extra argument to Realloc(), BOOL free_old_on_error
which is set appropriately by the SMB_REALLOC and SMB_REALLOC_KEEP_OLD_ON_ERROR
macros (and their array counterparts).
It remains to be seen what this will do to our Coverity bug count :-).

the name (must be abolute - start with /, must not end in /,
must have ./ and ../ removed). Of course for realpath resolved
paths this won't be the case but for others we need this name
to be canonicalized. This name is going into the sharemode db
for #3303 so needs to be in a normalized format.

only tell at parse time from the wire if an incoming name
has wildcards or not. If it's a mangled name and we demangle
the demangled name may contain wildcard characters. Ensure
these are ignored.

the 2 BOOL flags in dfs_redirect() down to one since
they both are used in essentially the same context
(from what we can tell).
Tested Win98SE, WinXP sp 1 & 2, Win2k3 sp1, and WIn2k Sp4.
All dfs operations still seem to work.

We did need the special case for RESOLVE_DFSPATH
in the findfirst() code.
Jeremy, please verify I haven't broken the allow_wcard
code you added to resolve_dfs_path()
