_netr_ServerPasswordSet2: use info level 26 to set plain text machine password

To support password change for machine or trusted domain accounts in Active
Directory environment we need to pass down actual plain text password
instead of NT hashes. This would allow a backend like ipasam to update
Kerberos keys as well as NT hashes.

By calling samr_SetUserInfo2 info level 26 we ensure PASSDB layer can
actually get the plain text password. If PASSDB backend implements
pdb_update_sam_account() callback, it then gets the plain text password
from samr_SetUserInfo2.

A plain text password is a data blob represented as up to 256 WCHARs. It
is UTF-16 coded on wire and we have its length from the buffer.
SetUserInfo2 SAMR call chain in decode_pw_buffer() does explicitly
expect 512+4 bytes in the buffer. It then calls convert_string_talloc()
to convert it to UNIX charset passing the correct value of the plaintext
password length. However, convert_string_talloc() expects the length of
input string *including* the terminating null and we pass just the
string length.

convert_string_talloc() then explicitly null-terminates the resulting
string by adding two nulls. In most cases UNIX charset is UTF-8, so we
get null-terminated UTF-8 string down to PASSDB layer.

MS-SAMR does not limit what does the password should contain.  It says
it is 'userPassword' value. Either 'userPassword' or 'unicodePwd' cannot
contain null characters according to MS-ADTS 3.1.1.3.1.5 because they
must be proper UTF-8 and UTF-16 strings accordingly.

We are talking to our own SAMR service here.

s3/smbd: make write time fetching async

Finally use the new async dbwrap_parse_record_send/recv() functions
respectively the fetch_share_mode_send/recv wrappers for fetching the
write time from locking.tdb.

Previously for a directory with n files we would sit idle in the
directory enumeration loop fo n * m seconds waiting for responses from
ctdb, where m is the response time in seconds for a dbwrap request via
ctbd.

This is known to kill performance and we even have a parameter
"smbd:search ask sharemode" that can be used to disable fetching the
write time from locking.tdb.

Using fetch_write_time_send() works this way: in the directory
enumeration loop that calls smbd_dirptr_lanman2_entry() to marshall the
directory entries we

1. call fetch_write_time_send() after calling smbd_dirptr_lanman2_entry
   passing a pointer to the current position in the marshall buffer.

2. If fetch_write_time_send() has set the out parameter "stop", we exit
   the enumeration loop. This is necessary because we only send dbwrap
   requests but don't consume the results. This has the potential to
   deadlock so we must stop sending requests as soon as our ctdb send
   queue is full.

3. In the fetch_write_time_done() callback, if the recv function got a
   locking.tdb record, we push the write time into the marshall buffer
   at the offet saved in the request state.

This new feature is still off by default as it doesn't
give any improvement in the non-clustered usecase.
"smbd:async search ask sharemode" can be used to activate it,
which makes only sense with "clustering = yes" (execept for testing).

s3/smbd: enable processing SMB2 requests async internally

main SMB2 processing engine that it wants to handle a requests
asynchronously internally.

This has two use cases:

- it allows (internal) async processing of compound requests that would
  otherwise be rejected by the SMB2 processing engine

- it preserves sync semantics at the SMB layer, some clients might not

lib: param: Remove the last external use of global_iconv_handle by calling the utility function reinit_iconv_handle().

Add an error check.

This *looks* like a logic change, but it is not.

The only change is the addition of the error return check.

The reason is that the changed function, reload_charcnv(),
is the *only* function that sets lp_ctx->iconv_handle. And
it does so just before setting global_iconv_handle = lp_ctx->iconv_handle.

Calling the utility function reinit_iconv_handle()
instead merely sets global_iconv_handle first, then
assigns it (as the return) to lp_ctx->iconv_handle.

So all this is doing is reversing the order of
setting global_iconv_handle and lp_ctx->iconv_handle
to the same thing.

Even the removal of the lines:

-       struct smb_iconv_handle *old_ic = lp_ctx->iconv_handle
-       if (old_ic == NULL) {
-               old_ic = global_iconv_handle;

has no effect, as remember that lp_ctx->iconv_handle
is only ever set to the same value as global_iconv_handle,
and once this function has been run once, lp_ctx->iconv_handle != NULL.

This allows us finally to make global_iconv_handle private
to the C source file that defines it.

vfs_acl_xattr: avoid needlessly supplying a large buffer to getxattr()

When obtaining the security descriptor via getxattr(), first try
optimistically to supply a buffer of 4K, and if that turns out
to be too small, determine the correct buffer size.

The previous behavior of falling back to a 64K buffer encountered
problem with Linux prior to version 3.6, due to pyisical memory
fragmentation. With those kernels, as long as the buffer is 8K or
smaller, getting the xattr is much less prone to failure due to
memory fragmentation.
