make HOST_NAME_MAX an alias of MAXHOSTNAMELEN

HOST_NAME_MAX is not available on Solaris/*BSD systems. However we
can use MAXHOSTNAMELEN on those platforms instead.

let automake to use correct libdir, when building ntlmssptest

We build 32-bit and 64-bit version of gss-ntlmssp. Each version is
configured with its own --libdir location to pickup correct shared
libraries. Command here configures 32-bit verson:

```
./configure --prefix=/usr \
	--mandir=/usr/share/man \
	--bindir=/usr/bin \
	--sbindir=/usr/sbin \
	--libdir=/usr/lib/ \
	--with-wbclient=no \
	--disable-dependency-tracking
```
this is configure comand for 64-bit version:
```
./configure --prefix=/usr \
	--mandir=/usr/share/man \
	--bindir=/usr/bin \
	--sbindir=/usr/sbin \
	--libdir=/usr/lib/amd64 \
	--with-wbclient=no \
	--disable-dependency-tracking
```

However linker fails to pick up correct location of libunistring, when
build 64-bit version.

The most important chancge in this pull request is introduction
of:

```
ntlmssptest_LDFLAGS = \
    -L$(libdir)
```

The other changes are just matter of taste as I want to make check
for libunistring dependency more obvious.

check for ucred does not seem to be required

I'm trying to build gss-ntlmssp on Solaris. Autoconf configure script
fails saying ucred.ucred_gid, ucred.ucred_uid members are missing.
Using grep(1) on sources indicates those members/ucred structure is
nowhere used. Removing this check makes code to build on Solaris.

gssntlmssp_la_LDFLAGS also requires libdir to pick up right libraries (64-bit vs 32-bit)

without this diff 64-bit build completes with warning below:

Add gssspi_mech_invoke method to turn on debugging

This allows to set a file of own chosing as well as turn on and off
debugging as needed.

Mostly thread safe, and applies to all threads at once.
There is a very small window for a race condition where a thread
modifies the debug_fd at the same time another thread is actually trying
to print a debug message.

In order to handle this case without the performance hit of a mutex on
every debug message, we change the implementation to use file
descriptors instead. printing to a closed file descriptor or to a -1
file descriptor returns an error but does not crash the process as it
happens when a file stream is NULL or pointing to freed memory.

Store the full SPN within a server gssntlm_name

The SPN is used to fill the Traget Name Attribute in the Target Info
array. This means we need to preserver the SPN as passed to us (via
conversion from a GSS Name).

This patch adds an spn field to the server union part of gssntlm_name
structure.

Always include a version field in NTLMSSP packets

It turns out that the version field structure must always be included
in packets, the flag only controls whether the structure is filled or
all zeros.
Add it directly to the wire structures, and change the encoding
functions accordingly.

Always set NTLMSSP_NEGOTIATE_VERSION

Setting the NTLMSSP_NEGOTIATE_VERSION flag makes most clients
generate a MIC correctly, while lack of version causes some clients to
omit a required empty version struct on the wire, which in turn causes
MIC checks to fail.

Revert the MSVAVFLAGS_UNVERIFIED_SPN flag default

By default SSPI does not set this flag, and setting it causes servers
with restrictive policy to fail authentication. Given no MS client sets
this flag by default, neither should we until there is a clear need.
We trust our calling applications to do the right thing here in any
case just like SSPI trusts their own calling applications.

Add option to set the default NEGOTIATE flags

This requires to explicitly acquire credentials before calling into
the ISC or ASC functions. Then setting the new default flags on the
credntial. It is not elegant to mix credentials and context flags,
but it is the only way to do it in GSSAPI currently, and there is
precedent in other mechanisms like KRB5.

Allow ntlm_seal even withon NEGOTIATE_SEAL

So according to Issue #77 we have an interop issue if we prevent the use
of gss_wrap when sealing has not been negotiated. On the technical side,
whether we negotiate sealing or not we always create a seal handle with
RC4.

Change behavior to allow applications to still wrap/unwrap data if they
want, even though the negotiation marked sealing as not selected.
The worst thing that can happen is that the peer application does no
like sealed content and bails.

Applications that need to avoid seeling should already just use
gss_get_mic() anyway and they can check the returned GSS flags to see if
sealing was negotiated (returned as GSS_CONF_FLAG), so applications
still have all they need to make their choice and be compatible with
whatever peer they need to speak to.

Thanks to Filip Navara for finding this.

Make gssntlm_import_name_by_mech more robust

This was reported by the GitHub Security Lab team as:
- Memory corruption when importing host-based service names (GHSL-2023-014)

However the only caller that could cause the issue report in a way that
culd lead to memory corruption is the application itself calling
gss_import_name with an invalid name buffer containing embedded zeros.

This is an invalid name for any GSSAPI mechanism and an incorrect use or
incorrect validation on the application side. As such I do not believe
this is a security or DoS issue in the gss-ntlmssp code, but will adopt
the proposed mitigation anyway as it makes the code more robust in the
face of application mistakes.

Out-of-bounds read in multiple decode functions

These were reported as:
- Out-of-bounds read in ntlm_decode_oem_str (GHSL-2023-019)
- Out-of-bounds read in ntlm_decode_u16l_str_hdr (GHSL-2023-020)
- Out-of-bounds read in ntlm_decode_field (GHSL-2023-021)

These are lall basically the same identical error replicated in 3
separate functions.

Fixes defects GHSL-2023-019, GHSL-2023-020, GHSL-2023-021 found by
the GitHub Security Lab team via oss-fuzz.

A 32-bit integer overflow condition can lead to incorrect checks of
consistency of length of internal buffers. This leads to a DoS
as the service may end up reading from unmapped memory and crashing.

Although most applications will error out before accepting a singe input
buffer of 4GB in lenght this could theoretically happen, and therefore
we fix it.

GHSL-2023-013: Memory corruption decoding UTF16

Memory corruption when decoding UTF16 strings (GHSL-2023-013)

Fixes defect GHSL-2023-013 found by the GitHub Security Lab team via
oss-fuzz.

The variable outlen was not initialized and could cause writing a zero
to an arbitrary place in memory if ntlm_str_convert() were to fail,
which would leave outlen uninitialized.

This can lead to a DoS if the write hits unmapped memory or randomly
corrupting a byte in the application memory space.

Make sure to zero out only if ntlm_str_convert() succeeds, but for good
measure also initialize outlen to 0.

GHSL-2023-012: Incorrect free when decoding target

Incorrect free when decoding target information (GHSL-2023-012)

Fixes defect GHSL-2023-012 found by the GitHub Security Lab team via
oss-fuzz.

The error condition incorrectly assumed the cb and sh buffers would
contain a copy of the data that needed to freed. However that is not the
case.

This will generally cause an assertion when trying to free a pointer
that was never allocated, and potentially memory corruption depending on
the contents fo the target_info buffer.

This may cause a DoS condition.

Out-of-bounds read when decoding target information (GHSL-2023-011)

Fixes defect GHSL-2023-011 found by the GitHub Security Lab team via
oss-fuzz.

The lenght of the av_pair is not checked properly for two of the
elements. In case the lenght is shorter than requires this may cause an
out-of-bound read that either reads garbage or may cause a crash by
reading unmapped memory.

This can be exploited to crash the service causing a DoS.
