Prevent wsrep files from being installed if WITH_WSREP=OFF.
Reviewed by Daniel Black
Additionally excluded #include wsrep files and galera* files
along with galera/wsrep tests.
mysql-test/include/have_wsrep.inc remainds as its used by
a few isolated tests.

Replace mysql-log-rotate.sh and debian/...mysql-server.logrotate with one
new unified and well documented version.
Name is mariadb.logrotate.in as in 10.11 branch onward we use now the
'mariadb' name, and use 'logrotate' to match the actual name of the
utility.
Also automatically disable deprecated /etc/logrotate.d/mysql-server
file on deb upgrades.

Reviewer edits made:
* Added 'su mysql mysql' to the logrotate this is more RPM friendly.
This is commented on Debian
* /var/log/mysql is the path on SuSe based distributions
Implement new mini-benchmark script for simple CPU bound benchmark for the
duration of 5 minutes. The script can be run stand-alone or as part of a
CI pipeline.
Extend Gitlab-CI to run mini-benchmark on every commit to catch if there
are severe performance regressions.
Also bump MARIADB_MAJOR_VERSION to 10.8 which is needed on the 10.8 branch.
... when two packages are installed.
(fc35 with i686 and x86_64 packages of libsepol installed).
$ rpm -q --qf "%{VERSION}" libsepol

Restricting the version to the current achitecture generates
a much more obtainable version dependency.
$ rpm -q --qf "%{VERSION}" libsepol.x86_64
3.3
This make dependency resolution easier preventing:

The CMAKE_SYSTEM_PROCESSOR is used in the generation of architecture
filenames so its preduent to just use the same version.
Systemd has a socket activation feature where a mariadb.socket
definition defines the sockets to listen to, and passes those
file descriptors directly to mariadbd to use when a connection
occurs.
The new functionality is utilized when starting as follows:
systemctl start mariadb.socket
The mariadb.socket definition only needs to contain the network
information, ListenStream= directives, the mariadb.service
definition is still used for service instigation.
When mariadbd is started in this way, the socket, port, bind-address
backlog are all assumed to be self contained in the mariadb.socket
definition and as such the mariadb settings and command line
arguments of these network settings are ignored.
See man systemd.socket for how to limit this to specific ports.
Extra ports, those specified with extra_port in socket activation
mode, are those with a FileDescriptorName=extra. These need
to be in a separate service name like mariadb-extra.socket and
these require a Service={mariadb.service} directive to map to the
original service. Extra ports need systemd v227 or greater
(not RHEL/Centos7 - v219) when FileDescriptorName= was added,
otherwise the extra ports are treated like ordinary ports.
The number of sockets isn't limited when using systemd socket activation
(except by operating system limits on file descriptors and a minimal
amount of memory used per file descriptor). The systemd sockets passed
can include any ownership or permissions, including those the
mariadbd process wouldn't normally have the permission to create.
This implementation is compatible with mariadb.service definitions.
Those services started with:
systemctl start mariadb.service
does actually start the mariadb.service and used all the my.cnf
settings of sockets and ports like it previously did.
Under WITHOUT_WSREP:
Exclude support files that are server only like
* wsrep.cnf
* wsrep_notify
* log rotate config files
* mysqld_multi
Exclude man pages of server components
liburing is a new optional dependency (WITH_URING=auto|yes|no)
that replaces libaio when it is available.
aio_uring: class which wraps io_uring stuff
aio_uring::bind()/unbind(): optional optimization
aio_uring::submit_io(): mutex prevents data race. liburing calls are
thread-unsafe. But if you look into it's implementation you'll see
atomic operations. They're used for synchronization between kernel and
user-space only. That's why our own synchronization is still needed.
For systemd, we add LimitMEMLOCK=524288 (ulimit -l 524288)
because the io_uring_setup system call that is invoked
by io_uring_queue_init() requests locked memory. The value
was found empirically; with 262144, we would occasionally
fail to enable io_uring when using the maximum values of
innodb_read_io_threads=64 and innodb_write_io_threads=64.
aio_uring::thread_routine(): Tolerate -EINTR return from
io_uring_wait_cqe(), because it may occur on shutdown
on Ubuntu 20.10 (Groovy Gorilla).
This was mostly implemented by Eugene Kosov. Systemd integration
and improved startup/shutdown error handling by Marko Mäkelä.
Create symlinks during configure time and install them. This is
necessary as Alias support from systemd service file was dropped with:
6af0bd6907
* Also ignore the generated symlinks in gitignore
..as they have their own tools that parses those files, such as
opensysusers[1] that handles sysusers file and opentmpfiles[2] that
handles tmpfiles.d settings
Because of this. Move both sysusers and tmpfiles 'if' function
outside systemd function, allowing independent install

Changes done by vicentiu@mariadb.org, from original author patch:
Installing sysusers and tmpfiles without checking for systemd existence
means that by default, cmake will ALWAYS install these files. Our
general policy is we do not install things which are not needed.
However, there is a valid use case when these files are useful, as is
described above.
To allow this, provide an extra switch that can be enabled during
configuring by doing -DINSTALL_SYSTEMD_{SYSUSERS|TMPFILES}=True
This will use the default path INSTALL_SYSTEMD_{SYSUSERS|TMPFILES}DIR
fetched from install_layout.cmake for rpm & deb based layouts
respectively, or they must be overriden if the install_layout is
standalone.
Example:
cmake . -DINSTALL_SYSTEMD_SYSUSERS=True -DINSTALL_SYSTEMD_SYSUSERSDIR=/etc/sysusers.d
These files were installed to:
${INSTALL_SYSTEMD_SYSUSERSDIR}/sysusers.conf
${INSTALL_SYSTEMD_TMPFILESDIR}/tmpfiles.conf
Instead rename the files to more descriptive file names 'mariadb.conf'.
Don't install server files if WITHOUT_SERVER is specified.
"Server files" are defined as files going into the MariaDB-Server RPM,
that is files in the components Server, ManPagesServer, Server_Scripts,
IniFiles, SuportFiles, and Readme.
