util:tsort.h: add a macro for safely comparing numbers
In many places we use `return a - b;` in a comparison function. This can
be problematic if the comparison is used in a sort, as `a - b` is not
guaranteed to do what we expect. For example:
* if a and b are 2s-complement ints, a is INT_MIN and b is INT_MAX, then
a - b = 1, which is wrong.
* if a and b are 64 bit pointers, a - b could wrap around many times in
a cmp function returning 32 bit ints. (We do this often).
The issue is not just that a sort could go haywire.
Due to a bug in glibc, this could result in out-of-bounds access:

ldb: avoid out of bounds read and write in ldb_qsort()
If a compare function is non-transitive (for example, if it evaluates
A > B and B > C, but A < C), this implementation of qsort could access
out-of-bounds memory. This was found in glibc's qsort by Qualys, and
their write-up for OSS-Security explains it very well:
An example of a non-transitive compare is one in which does this
int cmp(const void *_a, const void *_b)
{
int a = *(int *)_a;
int b = *(int *)_b;
return a - b;
}
which does the right thing when the magnitude of the numbers is small,
but which will go wrong if a is INT_MIN and b is INT_MAX. Likewise, if
a and b are e.g. uint32_t, the value can wrap when cast to int.
We have functions that are non-transitive regardless of subtraction.

ctdb-protocol: Add missing push support for new controls
CTDB_CONTROL_TCP_CLIENT_DISCONNECTED and
CTDB_CONTROL_TCP_CLIENT_PASSED were added in commits c6602b686b4e50d93272667ef86d3904181fb1ab and 037e8e449deb136ad5ed5e4de05439411b545b6d. They were missing test
support for the packet push/pull. While adding the testing (for
completeness, before adding another new control) I noticed that the
push functionality was absent. This adds that, along with the test
support.

gpo: Do not get templates list on first run
This is a visual fix and has no impact on functionality apart from
cleaner log messages.
The point of this is to get the list of supported templates in order to
compute a diff between the current applied templates and the updated
list, so we are able to unapply and reapply the policy in case there are
differences.
However this code path is executed on first applies as well, at which
point the root CA is not yet set up. This causes the
`get_supported_templates` call to fail, which is not a hard failure but
still pollutes the logs. In this case it's safe to avoid executing the
command as the policy will be applied regardless.

s3:passdb: smbpasswd reset permissions only if not 0600
Browsing files or download files from samba server, smbd would check user's
id to decide whether this user could access these files, by lookup user's
information from the password file (e.g. /usr/local/samba/private/smbpasswd).
smbd might goes through startsmbfilepwent(), this api calls [f]chmod() to
make sure the password file has valid permissions 0600.
Consider a scenario: we are doing a read performance benchmark about
downloading a bunch of files (e.g. a thousand files) from a samba server,
monitoring file system i/o activities counters, and expecting that should
be only read operations on file system because this is just downloading, no
uploading is involved. But actually found that still write operations on file
system, because smbd lookup user and always reset 0600 permissions on password
file while access each file, it makes dirty pages (inode modification) in ram,
later triggered a kernel journal daemon to sync dirty pages into back storage
(e.g. ext3 kjournald, or ext4 jbd2).
This looks like not friendly for read performance benchmark if it happened on
an entry-level systems with much less memory and limited computation power,
because dirty pages syncing in the meantime slows down read performance.
This patch adds fstat() before [f]chmod(), it would check whether password
file has valid permissions 0600 or not. If 0600 smbd would bypass [f]chmod()
to avoid making dirty pages on file systems. If not 0600 smbd would warn and
go through [f]chmod() to set valid permissions 0600 to password file as
earlier days.

selftest: remove error_inject from shadow_write share
Frankly, I can't remember why I added this as part of bug 13688. The
goal of the corresponding test is to verify a write on a read-only
file handle fails. As the file is opened O_RDONLY, the write will fail
anyway and there's no need to inject the error.
To make things worse, having the error injected meant we didn't notice
when the underlying logic of forcing the open to be done with O_RDONLY
was done as O_RDWR, resulting in the write on the handle to succeed.
This happened when we introduced reopen_from_fsp(): the initial
pathref open of a path with a twrp value was correctly detected and
handled by shadow_copy2_openat(). However, when converting the pathref
open to a real one via reopen_from_fsp(), shadow_copy2_openat() only
sees the magic /proc/fd path and has no way of inferring that this was
originating from a prevous version open with a twrp value.
Tl;dr: we can just remove this error injection, it is not needed, the
correct fix is to implement this in the SMB layer which is done in the
subsequent commits.
