Restructures parts of open code so that fsp must be allocated before calling
open_file_ntcreate(_internal). Also fix up file ref-counting inside files.c.
Jeremy.
This removes some explicit inbuf references and also removes a pointless check
in reply_echo. The buflen can never be more than 64k, this is just a 16 bit
value.
Ok, here's the fix for the write times breakage
with the new tests in S4 smbtorture.
The key is keeping in the share mode struct
the "old_file_time" as the real write time,
set by all the write and allocation calls,
and the "changed_write_time" as the "sticky"
write time - set by the SET_FILE_TIME calls.
We can set them independently (although I
kept the optimization of not setting the
"old_file_time" is a "changed_write_time"
was already set, as we'll never see it.
This allows us to update the write time
immediately on the SMBwrite truncate case,
SET_END_OF_FILE and SET_ALLOCATION_SIZE calls,
whilst still have the 2 second delay on the
"normal" SMBwrite, SMBwriteX calls.
I think in a subsequent patch I'd like to
change the name of these from "old_file_time"
to "write_time" and "changed_write_time" to
"sticky_write_time" to make this clearer.
I think I also fixed a bug in Metze's original
code in that once a write timestamp had been
set from a "normal" SMBwriteX call the fsp->update_write_time_triggered
variable was set and then never reset - thus
meaning the write timestamp would never get
updated again on subsequent SMBwriteX's.
The new code checks the update_write_time_event
event instead, and doesn't update is there's
an event already scheduled.
Metze especially, please check this over for
your understanding.

xp/2003 explorer freezes browsing shares on samba ipv6 hosts. Caused by missing
reply packet to SMB printclose packet.

one of our virtualised functions, such as db_open(), but error is only
set when a system call fails, and it is not uncommon for us to fail a
function internally without ever making a system call. That led to us
passing back success when a function had in fact failed.
I found two places where we relied on map_nt_error_from_unix()
returning success when errno==0, but lots and lots of places where we
relied on the reverse, so I fixed those two places.
map_nt_error_from_unix() will now always return an error, returning
NT_STATUS_UNSUCCESSFUL if errno is 0

case files. Reported by Daniel Johnson <Progman2000@usa.net>.
The smb_set_file_time() call to set the filetimes is failing
because it's using the unmodified name passed in by the
client, not the modified name (matching case on the
disk) that comes out from create_file().

fsp_belongs_conn only used the vuid struct member anyway, and this is available
in the smb_request structure as well.

We now never call file_ntimes() directly, every update
is done via smb_set_file_time().
This let samba3 pass the BASE-DELAYWRITE test.
The write time is only updated 2 seconds after the
first write() on any open handle to the current time
(not the time of the first write).
Each handle which had write requests updates the write
time to the current time on close().
If the write time is set explicit via setfileinfo or setpathinfo
the write time is visible directly and a following close
on the same handle doesn't update the write time.

This is needed to implement the strange write time update
logic later. We need to store 2 time timestamps to
distinguish between the time the file system had before
the first client opened the file and a forced timestamp update.
