Because we didn't count the null terminator, we would not move past it
in the packet.

of associated functions.
The motivation for this change was to avoid having to convert to/from
ucs2 strings for so many operations. Doing that was slow, used many
static buffers, and was also incorrect as it didn't cope properly with
unicode codepoints above 65536 (which could not be represented
correctly as smb_ucs2_t chars)
The two core functions that allowed this change are next_codepoint()
and push_codepoint(). These functions allow you to correctly walk a
arbitrary multi-byte string a character at a time without converting
the whole string to ucs2.
While doing this cleanup I also fixed several ucs2 string handling
bugs. See the commit for details.
The following code (which counts the number of occuraces of 'c' in a
string) shows how to use the new interface:
size_t count_chars(const char *s, char c)
{
size_t count = 0;
while (*s) {
size_t size;
codepoint_t c2 = next_codepoint(s, &size);
if (c2 == c) count++;
s += size;
}
return count;
}

taking a context (so when you pass a NULL pointer you end up with
memory in a top level context). Fixed it by changing the API to take a
context. The context is only used if the pointer you are reallocing is
NULL.

const warnings for a long time, and no real way to approach a
solution. Some of them are unavoidable due to the way the C standard
works (for example, any function that provides strchr() like
functionality _must_ produce a const warning)
I will be converting a bunch of places that currently produce const
warnings to use the discard_const_p(). Some of these will be
unavoidable const problems, some of them will be ones we will fix up
over time. At least this change means we will no longer be swamped
with const warnings, and we will easily be able to see when new
problems emerge.

occur as secondary bytes in any multi-byte character set. This
allows for a very simple optimisation in strchr_m() and
strrchr_m(). It might be a good idea to pick this up for Samba3.
- the horrible toktocliplist() is only used in clitar.c, so move it
there, to prevent anyone else from being tempted to use it.

The intial motivation for this commit was to merge in some of the
bugfixes present in Samba3's chrcnv and string handling code into
Samba4. However, along the way I found a lot of unused functions, and
decided to do a bit more...
The strlen_m code now does not use a fixed buffer, but more work is
needed to finish off other functions in str_util.c. These fixed
length buffers hav caused very nasty, hard to chase down bugs at some
sites.
The strupper_m() function has a strupper_talloc() to replace it (we
need to go around and fix more uses, but it's a start). Use of these
new functions will avoid bugs where the upper or lowercase version of
a string is a different length.
I have removed the push_*_allocate functions, which are replaced by
calls to push_*_talloc. Likewise, pstring and other 'fixed length'
wrappers are removed, where possible.
I have removed the first ('base pointer') argument, used by push_ucs2,
as the Samba4 way of doing things ensures that this is always on an
even boundary anyway. (It was used in only one place, in any case).

This version does the following:
1) talloc_free(), talloc_realloc() and talloc_steal() lose their
(redundent) first arguments
2) you can use _any_ talloc pointer as a talloc context to allocate
more memory. This allows you to create complex data structures
where the top level structure is the logical parent of the next
level down, and those are the parents of the level below
that. Then destroy either the lot with a single talloc_free() or
destroy any sub-part with a talloc_free() of that part
3) you can name any pointer. Use talloc_named() which is just like
talloc() but takes the printf style name argument as well as the
parent context and the size.
The whole thing ends up being a very simple piece of code, although
some of the pointer walking gets hairy.
So far, I'm just using the new talloc() like the old one. The next
step is to actually take advantage of the new interface
properly. Expect some new commits soon that simplify some common
coding styles in samba4 by using the new talloc().

- added server side support for schannel type 23. This allows WinXP to establish a schannel connection
to Samba4 as an ADS DC
- added client side support for schannel type 23, but disabled it as currently the client
code has now way of getting the fully qualified domain name (which is needed)
- report dcerpc faults in the server code in the log

Samba's NTLMSSP code is now fully talloc based, which should go a long
way to cleaning up the memory leaks in this code. This also avoids a
lot of extra copies of data, as we now allocate the 'return' blobs on
a caller-supplied context.
I have also been doing a lot of work towards NTLM2 signing and
sealing. I have this working for sealing, but not for the verifier
(MD5 integrity check on the stream) which is still incorrect.
(I can aim a rpcecho sinkdata from a Win2k3 box to my server, and the
data arrives intact, but the signature check fails. It does however
match the test values I have...).
The new torture test is cludged in - when we get a unit test suite
back, I'll happliy put it in the 'right' place....
