3123271062 s3:blocking: fix the fsp->blocked_smb1_lock_reqs handling
A new request is first checks against all pending
requests before checking the already granted locks.

Before we retried the lock array of another request
(the first in the list), but then finished current request,
which is wrong.

efd4832c2c CVE-2019-10197: smbd: split change_to_user_impersonate() out of change_to_user_internal()
This makes sure we always call chdir_current_service() even
when we still impersonated the user. Which is important
in order to run the SMB* request within the correct working directory
and only if the user has permissions to enter that directory.

It makes sure we always update conn->lastused_count
in chdir_current_service() for each request.

Note that vfs_ChDir() (called from chdir_current_service())
maintains its own cache and avoids calling SMB_VFS_CHDIR()
if possible.

It means we still avoid syscalls if we get a multiple requests
for the same session/tcon tuple.

538ffe1960 tests: ensure that most python scripts have usage text
When a script is run with the wrong arguments, it should at least say
something like this:

    Usage: samba-foo [OPTIONS]

For many samba scripts, especially without a server environment, having
no arguments is the wrong arguments.

Here we look for every executable file with '#![...]python[3]' on the
first line, and exclude certain files and directories that have excuses
to fail the test. For example, many selftest scripts are stream-oriented
and will hang forever waiting for stdin, which is not an error. Some
test modules are designed so they can be optionally run from the command
line, but this option is typically only used by the developer who is
writing them.

98848142cd repl_md: Avoid dropping cross-partition links
Cross-partition links could still be dropped if GET_TGT was already
previously set for the replication.

This was due to a slight error in the order of logic. We never want to
ignore cross-partition links (regardless of whether the TARGETS_UPTODATE
/GET_TGT flag is set). We should only be returning early in the
GET_TGT case if the objects are both in the same partition.

BUG: https://bugzilla.samba.org/show_bug.cgi?id=14022
RN: When the AD domain contained a linked attribute that spanned
partitions, DRS replication could drop the link. This dropped link could
then result in subtle differences in behaviour between DCs, as some DCs
would have the link and others wouldn't. When this issue occurred, the
dropped link would be logged in a warning message:
 "<target-dn> is Unknown but up to date. Ignoring link from <source-dn>"
This issue would not always occur - it depended a lot on the database
contents. Typically, it would only potentially occur when joining a new
DC to the domain (doing an ldapcmp after the join would also highlight
the problem, if it occurred). This issue has now been resolved.

The test is exercising the client-side code by using the 'samba-tool drs

we force the client code to retry with the GET_TGT flag set.
