s3:util: Move static file_pload() function to lib/util
file_pload() is static private function in Samba3 library, however it
does not have any special dependencies and might be widely used as
common function, so moving it into common samba-util library.
Extra fix needed to enable easy back-port of code for:
trigger the immediate leading to do_break_to_none. This goes through
because fsp->oplock_type is not initialized yet, thus 0. Also,
file_has_read_oplocks is still valid, because the smbd that has died
could not clean up the brlock.tdb entry.
Later in the code the exclusive oplock is granted, which is then found
by do_break_to_none, making it panic.
This patch just runs the direct FTRUNCATE instead of vfs_set_filelen.
This means the contend_level2_oplock code is skipped.
The relevant break (LEVEL_II to NONE) is now done in delay_for_oplock()
with the nice effect of removing a comment that was very confusing to
me.

s3: winbind: Fix crash when invoking winbind idmap scripts.
Previously the private context was caching a pointer to

on config file reload. Ensure the string is talloc_strup'ed

s3:loadparm: Ensure to truncate FS Volume Label at multibyte boundary
For FS_VOLUME_INFO/FS_INFO operation, a maximum of 32 characters are
sent back. However, since Samba chops off any share name with >32
bytes at 32, it is possible that a multi-byte share name can get chopped
off between a full character. This causes the string decoding for unicode
failure which sends back NT_STATUS_ILLEGAL_CHARACTER (EILSEQ) to the client
applications.
On Windows, Notepad doesn't like it, and refuses to open a file in this
case and fails with the following error:
Invalid character. For multibyte character sets, only the leading byte is
included without the trailing byte. For Unicode character sets, include
the characters 0xFFFF and 0xFFFE.
Proposed fix:
- Find the last starting point of a multibyte codepoint if the character
at 32nd byte is a subsequent byte of a MB codepoint.

The problem is that at the successful end of these functions
el->values is overwritten with new_values. However get_parsed_dns()
points p->v at the supplied el and it effectively gets used
as a working area by replmd_build_la_val(). So we must duplicate it
because our caller only called ldb_msg_copy_shallow().
The reason this matters is that the audit_log module is
above repl_meta_data in the stack, and tries to log the
ldb_message it saw after the reply (to include the error code).
If that ldb_message is changed it is not only misleading,
it can point to memory that has since gone away.
In this case the memory for the full extended DN in the
member attribute ended up on 'ac', a context lost by
the time repl_meta_data has finished processing.

When issued from a client, the detach control re-broadcasts itself
asynchronously to all nodes and then returns success. The controls to
some nodes to do the actual detach may still be in flight when success
is returned to the client. Therefore, the test should wait for a few
seconds to allow the asynchronous controls to complete.
The same is true for the attach control, so workaround the problem in
the attach test too.
An alternative is to make the attach and detach controls synchronous
by avoiding the broadcast and waiting for the results of the
individual controls sent to the nodes. However, a simple
implementation would involve adding new nested event loops.

In run_proc, there was an implicit assumption that when a process exits,
fd event (pipe between parent and child) would be processed first and
signal event (SIGCHLD for the child) would be processed later.
However, that is not the case. SIGCHLD can be received asynchronously
any time even when the pipe data has not fully been read. This causes
run_proc to miss some of the output from child process in tests.
When SIGCHLD is being processed, if the pipe between parent and child is
still open, then do an explict read from the pipe to ensure we read any
data still in the pipe before closing the pipe.

ctdb-daemon: Revert "We can not assume that just because we could complete a TCP handshake"
We also can not assume that nodes can be marked as connected via only
the keepalive mechanism. Keepalives are not sent to disconnected
nodes so, in the absence of other packets (e.g. broadcasts), 2 nodes
may never become marked as connected to each other.
Revert to marking nodes as connected in the TCP transport code. If a
connection is to a non(-operational) ctdbd then it will revert to
disconnected after a short while and may actually flap. This should
be rare.

memcache: Increase size of default memcache to 512k
With the fixed accounting of talloc objects, the default cache size
needs to increase. The exact increase required depends on the workloads,
going form 256k to 512k seems like a reasonable guess.
memcache: Properly track the size of talloc objects
With memcache_add_talloc, the talloc object becomes part of the pool and
the memcache_element stores a pointer to the talloc object. The
size of the the talloc object was not used when tracking the used space,
allowing the cache to grow larger than defined in the memcache_init
call.
Fix this by adding the size of the talloc object to the used space.
Also record the initial size of the talloc object for proper adjustment
of the used space in the cache later. This is in case the size of the
talloc object is modified while being owned by the cache (e.g.
allocating talloc child objects). This should never happen, but better
be safe than ending up with a broken cache usage counter.
