cb578bbe01 Fix possible "nmalloc >= ndalloc" assertion 
In arena_stats_merge() first nmalloc was read, and after ndalloc.

However with this order, it is possible for some thread to incement
ndalloc in between, and then nmalloc < ndalloc, and assertion will fail,
like again found by ClickHouse CI [1] (even after #2234).

  [1]: https://github.com/ClickHouse/ClickHouse/issues/31531

Swap the order to avoid possible assertion.

4fc5c4fbac New configure option '--enable-pageid' for Linux 
The option makes jemalloc use prctl with PR_SET_VMA to tag memory mappings with
"jemalloc_pg" or "jemalloc_pg_overcommit". This allows to easily identify
jemalloc's mappings in /proc/<pid>/maps. PR_SET_VMA is only available in Linux
5.17 and above.

eb65d1b078 Fix FreeBSD system jemalloc TSD cleanup 
Before this commit, in case FreeBSD libc jemalloc was overridden by another
jemalloc, proper thread shutdown callback was involved only for the overriding
jemalloc. A call to _malloc_thread_cleanup from libthr would be redirected to
user jemalloc, leaving data about dead threads hanging in system jemalloc. This
change tackles the issue in two ways. First, for current and old system
jemallocs, which we can not modify, the overriding jemalloc would locate and
invoke system cleanup routine. For upcoming jemalloc integrations, the cleanup
registering function will also be redirected to user jemalloc, which means that
system jemalloc's cleanup routine will be registered in user's jemalloc and a
single call to _malloc_thread_cleanup will be sufficient to invoke both
callbacks.

78b58379c8 Fix possible "nmalloc >= ndalloc" assertion. 
It is possible that ndalloc will be updated before nmalloc, in
arena_large_ralloc_stats_update(), fix this by reorder those calls.

It was found by ClickHouse CI, that periodically hits this assertion [1].

  [1]: https://github.com/ClickHouse/ClickHouse/issues/31531

That issue contains lots of examples, with core dump and some gdb output [2].

Here you can see that they differs only by 1.

ca709c3139 Fix failed assertion due to racy memory access 
While calculating the number of stashed pointers, multiple variables
potentially modified by a concurrent thread were used for the
calculation.  This led to some inconsistencies, correctly detected by
the assertions.  The change eliminates some possible inconsistencies by
using unmodified variables and only once a concurrently modified one.
The assertions are omitted for the cases where we acknowledge potential
inconsistencies too.
