lib/replace - add extra check to bsd_attr_list
The FreeBSD extattr API may return success and truncated
namelist. We need to check for this in bsd_attr_list to
ensure that we don't accidentally read off the end of the
buffer. In the case of a truncated value, the pascal
strings for attr names will reflect the lengths as if
the value were not truncated. For example:
`58DosStrea`
In case of short read we now set error to ERANGE and
fail.

The use of reload_services() has a lot of side effects, e.g. reopen of
log files and other things, which are only useful in smbd, but not in rpcd_classic.
It was also unloading the user and registry shares we loaded a few lines
above.

to read root only smb.conf files, access registry shares, ...

smbd: Hide the SMB1 posix symlink behaviour behind UCF_LCOMP_LNK_OK
This will be used in the future to also open symlinks as reparse
points, so this won't be specific to only SMB1 posix extensions.
I have tried to avoid additional flags for several weeks by making
openat_pathref_fsp or other flavors of this to always open fsp's with
symlink O_PATH opens, because I think NT_STATUS_OBJECT_NAME_NOT_FOUND
with a valid stat is a really bad and racy way to express that we just
hit a symlink, but I miserably failed. Adding additional flags (another one
will follow) is wrong, but I don't see another way right now.
NTTRANS-FSCTL needs changing: Windows 2016 returns INVALID_BUFFER_SIZE
instead of our NOT_A_REPARSE_POINT. This is not the whole story, but
this smbtorture3 change makes autobuild survive.

lib/compression: add simple python bindings
There are four functions, allowing compression and decompression in
the two formats we support so far. The functions will accept bytes or
unicode strings which are treated as utf-8.
The LZ77+Huffman decompression algorithm requires an exact target
length to decompress, so this is mandatory.
The plain decompression algorithm does not need an exact length, but
you can provide one to help it know how much space to allocate. As
currently written, you can provide a short length and it will often
succeed in decompressing to a different shorter string.
These bindings are intended to make ad-hoc investigation easier, not
for production use. This is reflected in the guesses about output size
that plain_decompress() makes if you don't supply one -- either they
are stupidly wasteful or ridiculously insufficient, depending on
whether or not you were trying to decompress a 20MB string.
>>> a = '12345678'
>>> import compression
>>> b = compression.huffman_compress(a)
>>> b
b'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 #....
>>> len(b)
262
>>> c = compression.huffman_decompress(b, len(a))
>>> c
b'12345678' # note, c is bytes, a is str
>>> a
'12345678'
>>> d = compression.plain_compress(a)
>>> d
b'\xff\xff\xff\x0012345678'
>>> compression.plain_decompress(d) # no size specified, guesses
b'12345678'
>>> compression.plain_decompress(d,5)
b'12345'
>>> compression.plain_decompress(d,0) # 0 for auto
b'12345678'
>>> compression.plain_decompress(d,1)
b'1'
>>> compression.plain_decompress(a,444)
Traceback (most recent call last):
compression.CompressionError: unable to decompress data into a buffer of 444 bytes.
>>> compression.plain_decompress(b,444)
b'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 #...
That last one decompresses the Huffman compressed file with the plain
compressor; pretty much any string is valid for plain decompression.

vampire_dc is an additional DC in the SAMBADOMAIN "started" by ad_dc_ntvfs, so
by joining ad_member_s3_join to the SAMBADOMAIN, it is member of a domain with
more then one DC.
Subsequently I'll add a test that needs such an environment.

the renamed function find_new_dc().
find_dc() now either returns a connected to the preferred DC or a new DC until
all possible DCs are exhausted and cm_open_connection() can just call find_dc()
to get a connected socket and pass it to cm_prepare_connection().
While at it reorder the args of find_dc() and make the only real out arg "fd"
