f6b9a29820 MDEV-16662: cmake remove empty INSTALL_DEBUG_TARGET 
No adverse effects since this was made a null function in
6b53f9d781.

This function had the last remaining cmake CMP0026 violation.

b9689712e0 MDEV-21374: When "--help --verbose" prints out configuration file paths, the --defaults-file option is not considered 
* `--defaults-file` option is showed only in `--help --verbose` if
applied
* `--default-extra-file` is showing correctly now in `--help --verbose`,
previously it was treated as a directory with appended `my.cnf`

fb01cc3766 my_getncpus based on threads available 
Detecting the cpus based on sysconf of the online CPUs can significantly
over estimate the number of cpus available.

Wheither via numactl, cgroups, taskset, systemd constraints, docker
containers and probably other mechanisms, the number of threads mysqld
can be run on can be quite less.

As such we use the pthread_getaffinity_np function on Linux and FreeBSD
(identical API) to get the number of CPUs.

The number of CPUs is the default for the thread_pool_size and a too
high default will resulting in large memory usage and high context
switching overhead.

Closes PR #922

daaa881cfe libpmem cmake macros 
Also added support for MAP_SYNC. It allows to achieve decent performance
with DAX devices even when libpmem is unavailable.

Fixed Windows version of my_msync(): according to manual FlushViewOfFile()
may return before flush is actually completed. It is advised to issue
FlushFileBuffers() after FlushViewOfFile().

744d545fd7 restore support for --defaults-file=<(...) 
if my_realpath() fails, don't return the error code, get_defaults_options()
returns a number of options consumed, not 0=ok/1=error.

instead, ignore the error from my_realpath. If it fails it internally
falls back to my_load_path, which restores 10.4- behavior

ba95c303e3 MDEV-21167 LF_PINS::stack_ends_here inaccurate, leading to alloca() larger than stack 
Use my_thread_var::stack_ends_here inside lf_pinbox_real_free() for address
where thread stack ends.

Remove LF_PINS::stack_ends_here.
It is not safe to assume that mysys_var that was used during pin allocation,
remains correct during free. E.g with binlog group commit in Innodb,
that frees pins for multiple Innodb transactions, it does not work
correctly.

ad17c98dd5 MDEV-16264 - prerequisite patch, periodic thr_timer 
Threadpool will need a functionality for periodic thr_timer
(the threadpool maintainence task is a timer that runs periodically).

Also increase the stack size for the timer thread, 8k won't be enough.
