s3: Fix to dptr_Close
This fixes a bitmap "leak" in dptr_Close by making it use the same internal
routines the rest of the code does.

We use (uid_t)0 here not sec_initial_uid() as make test uses a single user context.
I will revisit this when all the uid check changes are complete.

struct current_user current_user;"."
As requested by Volker, split this into smaller commits.
Jeremy.

Use accessor functions to get to this value. Tidies up much of
the user context code. Volker, please look at the changes in smbd/uid.c
to familiarize yourself with these changes as I think they make the
logic in there cleaner.
Cause smbd/posix_acls.c code to look at current user context, not
stored context on the conn struct - allows correct use of these
function calls under a become_root()/unbecome_root() pair.
Jeremy.

The code I just removed was checked in with e5466fffc286a99f as a bug fix for
https://bugzilla.samba.org/show_bug.cgi?id=3319. With the changes to
is_visible_file made with 9e8b8f8c16612 these lines have become unnecessary,
even with "hide unreadable = yes" dead msdfs symlinks show. This is because we
can not stat(2) them and default to showing them.
Why this change? I have a user who wants to use "hide unreadable" on msdfs
links. Because you can't edit acls on symlinks themselves, the user created the
targets as bogus, empty files that just exist as acl placeholders. With the
code in place that this patch removes, we never allow this to work.
Jeremy, please check! :-)
Thanks,
Volker

In very hot codepaths like the statcache copy_smb_filename and the subsequent
recursive talloc_free is noticable in the CPU load.

This is a hot codepath (called from the stat cache)

This vop is designed to work in tandem with SMB_VFS_READDIR to allow
vfs modules to make modifications to arbitrary filenames before
they're consumed by callers. Subsequently the core directory
enumeration code in smbd is now changed to free the memory that may be
allocated in a module. This vop enables the new version of catia in
the following patch.

They're both only used in the context of a function,
so we can make them stack variables.

This patch introduces two new temporary helper functions
vfs_stat_smb_fname and vfs_lstat_smb_fname. They basically allowed me
to call the new smb_filename version of stat, while avoiding plumbing
it through callers that are still too inconvenient. As the conversion
moves along, I will be able to remove callers of this, with the goal
being to remove all callers.
There was also a bug in create_synthetic_smb_fname_split (also a
temporary utility function) that caused it to incorrectly handle
filenames with ':'s in them when in posix mode. This is now fixed.

This patch introduces
struct stat_ex {
dev_t st_ex_dev;
ino_t st_ex_ino;
mode_t st_ex_mode;
nlink_t st_ex_nlink;
uid_t st_ex_uid;
gid_t st_ex_gid;
dev_t st_ex_rdev;
off_t st_ex_size;
struct timespec st_ex_atime;
struct timespec st_ex_mtime;
struct timespec st_ex_ctime;
struct timespec st_ex_btime; /* birthtime */
blksize_t st_ex_blksize;
blkcnt_t st_ex_blocks;
};
typedef struct stat_ex SMB_STRUCT_STAT;
It is really large because due to the friendly libc headers playing macro
tricks with fields like st_ino, so I renamed them to st_ex_xxx.
Why this change? To support birthtime, we already have quite a few #ifdef's at
places where it does not really belong. With a stat struct that we control, we
can consolidate the nanosecond timestamps and the birthtime deep in the VFS
stat calls.
At this moment it is triggered by a request to support the birthtime field for
GPFS. GPFS does not extend the system level struct stat, but instead has a
separate call that gets us the additional information beyond posix. Without
being able to do that within the VFS stat calls, that support would have to be
scattered around the main smbd code.
It will very likely break all the onefs modules, but I think the changes will
be reasonably easy to do.

This is a follow up to 69d61453df6019caef4e7960fa78c6a3c51f3d2a to
adjust the API to allow the lower layers allocate memory. Now the
memory can explicitly be freed rather than relying on talloc_tos().

Often times before creating a file, a client will first query to see
if it already exists. Since some systems have a case-insensitive stat
that is called from unix_convert, we can definitively return
STATUS_NO_SUCH_FILE to the client without scanning the whole
directory.
This code path is taken from trans2querypathinfo, but trans2findfirst
still does a full directory scan even though the get_real_filename
(the case-insensitive stat vfs call) can prevent this.
This patch adds the get_real_filename call to the trans2find* path,
and also changes the vfs_default behavior for
SMB_VFS_GET_REAL_FILENAME. Previously, in the absence of a
get_real_filename implementation, we would fallback to the full
directory scan. The default behavior now returns -1 and sets errno to
EOPNOTSUPP. This allows SMB_VFS_GET_REALFILENAME to be called from
trans2* and unix_convert.

search requests.
By default this VFS call is a NOOP, but the onefs vfs module takes advantage
of it to initialize direntry search caches at the beginning of each
TRANS2_FIND_FIRST, TRANS2_FIND_NEXT, SMBffirst, SMBsearch, and SMBunique

* VFS_OP_READDIR can now provide stat information, take advantage of it
if it's available
* is_visible_file(): optimistically expect the provided stat buffer is
already valid
* dptr_ReadDirName(): refactor code for easier readability, functionality
is the same

The goal is to move all this variables into a big context structure.

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.

If we know the underlying filesystem is case-insensitive, then we
know that it won't help to search for case variations of the requested
