bc7ba7afee MDEV-27758: Errors when building Connect engine on os x 11.6.2
Added checking for support of vfork by a platform where
building being done. Set HAVE_VFORK macros in case vfork()
system call is supported. Use vfork() system call if the
macros HAVE_VFORK is set, else use fork().

f502ccbcb5 Link with libatomic to enable C11 atomics support
Some architectures (mips) require libatomic to support proper
atomic operations. Check first if support is available without
linking, otherwise use the library.

48141f3c17 Replace mallinfo with mallinfo2 on supported systems
`mallinfo` is deprecated since glibc 2.33 and has been replaced by mallinfo2.
The deprecation causes building the server to fail if glibc version is > 2.33.

Check if mallinfo2 exist on the system and use it instead.

e6cb263ef3 MDEV-15961: Fix stacktraces under FreeBSD (aarch64)
Largely based on MySQL commit
75271e51d6

MySQL Ref:
    BUG#24566529: BACKPORT BUG#23575445 TO 5.6

    (cut)
    Also, the PTR_SANE macro which tries to check if a pointer
    is invalid (used when printing pointer values in stack traces)
    gave false negatives on OSX/FreeBSD. On these platforms we
    now simply check if the pointer is non-null. This also removes
    a sbrk() deprecation warning when building on OS X. (It was
    before only disabled with building using XCode).

Removed execinfo path of MySQL patch that was already included.

sbrk doesn't exist on FreeBSD aarch64.

Removed HAVE_BSS_START based detection and replaced with __linux__
as it doesn't exist on OSX, Solaris or Windows.  __bss_start
exists on mutiple Linux architectures.

Tested on FreeBSD and Linux x86_64. Being in FreeBSD ports for 2
years implies a good testing there on all FreeBSD architectures there
too. MySQL-8.0.21 code is functionally identical to original commit.

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.

6718d3bc32 MDEV-21082: isnan/isinf compilation errors, isfinite warnings on MacOS
The fix consists of three commits backported from 10.3:

1) Cleanup isnan() portability checks

(cherry picked from commit 7ffd7fe962)

2) Cleanup isinf() portability checks

Original problem reported by Wlad: re-compilation of 10.3 on top of 10.2
build would cache undefined HAVE_ISINF from 10.2, whereas it is expected
to be 1 in 10.3.

std::isinf() seem to be available on all supported platforms.
(cherry picked from commit bc469a0bdf)

3) Use std::isfinite in C++ code

This is addition to parent revision fixing build failures.

042fc29597 MDEV-19845: Adaptive spin loops
Starting with the Intel Skylake microarchitecture, the PAUSE
instruction latency is about 140 clock cycles instead of earlier 10.
On AMD processors, the latency could be 10 or 50 clock cycles,
depending on microarchitecture.

Because of this big range of latency, let us scale the loops around
the PAUSE instruction based on timing results at server startup.

my_cpu_relax_multiplier: New variable: How many times to invoke PAUSE
in a loop. Only defined for IA-32 and AMD64.

my_cpu_init(): Determine with RDTSC the time to run 16 PAUSE instructions
in two unrolled loops according, and based on the quicker of the two
runs, initialize my_cpu_relax_multiplier. This form of calibration was
suggested by Mikhail Sinyavin from Intel.

LF_BACKOFF(), ut_delay(): Use my_cpu_relax_multiplier when available.

ut_delay(): Define inline in my_cpu.h.

UT_COMPILER_BARRIER(): Remove. This does not seem to have any effect,
because in our ut_delay() implementation, no computations are being
performed inside the loop. The purpose of UT_COMPILER_BARRIER() was to
prohibit the compiler from reordering computations. It was not
emitting any code.

2a576f71c5 cmake: fix ucontext detection
On some archs uclibc does not provide the ucontext structure despite
providing ucontext.h, for details see
https://git.buildroot.net/buildroot/commit/?id=f1cbfeea95e6287c7a666aafc182ffa318eff262

This patch improves the detection of ucontext by making sure that
HAVE_UCONTEXT_H is only set when makecontext() was found.

26e5f9dda1 MDEV-14229: Stack trace is not resolved for shared objects
Resolving a stacktrace including functions in dynamic libraries requires
us to look inside the libraries for the symbols. Addr2line needs to be
started with the correct binary for each address on the stack. To do this,
figure out which library it is using dladdr, then if the addr2line
binary was started with a different binary, fork it again with the
correct one.

We only have one addr2line process running at any point during the
stacktrace resolving step. The maximum number of forks for addr2line should
generally be around 6.

One for server stacktrace code, one for plugin code, one when going back
into server code, one for pthread library, one for libc, one for the
_start function in the server. More can come up if plugin calls server
function which goes back to a plugin, etc.
