CMake WSREP=ON has some implications for client
executables so still present this as an option
when compiling WITHOUT_SERVER. In this case
default to ON for maximium compatibility of
the build client executables and libraries.
Now that we do not pollute systemd's environment but write private
environment files running these as root is not longer required. So
let's drop `PermissionsStartOnly=true`.
Debian adds extra `ExecStartPre=` and `ExecStartPost=`, though.
Use special executable prefix for full privileges there. (See
systemd.service(5) for details.)
MDEV-32188 make TIMESTAMP use whole 32-bit unsigned range
This is done by changing my_time_t from long to unsigned long.
The effect of this is that on windows compling old clients may
get warnings of if they compare my_time_t with as signed variable.
Other things
- Removed my_time_t from include/*.pp files as it is different on windows
and linux.
- Changed do_abi_check.cmake to first print abi_check and then the
conflicting file (this makes it easier to find the cause of the error).
- ZLIB_LIBRARIES, not ZLIB_LIBRARY
- ZLIB_INCLUDE_DIRS, not ZLIB_INCLUDE_DIR
For building libmariadb, ZLIB_LIBRARY/ZLIB_INCLUDE_DIR are still defined
This workaround will be removed later.
Improve detection for DES support in OpenSSL, to allow compilation
against system OpenSSL without DES.
Note that MariaDB needs to be compiled against OpenSSL-like library
that itself has DES support which cmake detected. Positive detection
is indicated with CMake variable HAVE_des 1.

`FindZLIB` module uses variable `ZLIB_ROOT`[1] to look for libraries. By
setting the variable, `FindZLIB` is able to search the libraries that
installed in a non-system path (/workspace/mylib for example).
And when using `z` in `LINK_LIBRARIES()` CMake tries to lookup the
library in system path by default. It doesn't work if the library isn't
installed in the path, and use ${ZLIB_LIBRARY} which set by FindZLIB
solve the issue.

The libpmem dependency that had been added in
commit 3daef523af (MDEV-17084)
did not achieve any measurable performance improvement when
comparing the same PMEM device with and without "mount -o dax"
using the Linux ext4 file system.
Because Red Hat has deprecated libpmem, let us remove the code
altogether.
Note: This is a 10.6 version of
commit 3f9f5ca48e
which will retain PMEM support in MariaDB Server 10.11.
Because the Red Hat Enterprise Linux 8 core repository does not include
libpmem, let us implement the necessary subset ourselves.
pmem_persist(): Implement for 64-bit x86, ARM, POWER, RISC-V, Loongarch
in a way that should be compatible with the https://github.com/pmem/pmdk/
implementation of pmem_persist().
The CMake option WITH_INNODB_PMEM can be used for enabling or disabling
this interface at compile time. By default, it is enabled on all applicable
systems that are covered by our CI system.
Note: libpmem had not been previously enabled for Loongarch in our
Debian packaging. It was enabled for RISC-V, but we will not enable it
by default on RISC-V or Loongarch because we lack CI coverage.
The generated code for x86_64 was reviewed and tested on two
Intel implementations: one that only supports clflush, and
another that supports both clflushopt and clwb.
The generated machine code was also reviewed on https://godbolt.org
using various compiler versions. Godbolt helpfully includes an option
to compile to binary code and display the encoding, which was
useful on POWER.
