Subject: [PATCH] Issue 5909 - Multi listener hang with 20k connections (#5917)
Bug Description: A fix for connection sub-table to freelist mapping results
in an uninitialised head of the sub-table linked list.
Fix Description: During connection table creation, initialise all elements but
skip the list head during the mapping phase.
Fixes: https//github.com/389ds/389-ds-base/issues/5909

Subject: [PATCH] issue 5924 - ASAN server build crash when looping
opening/closing connections (#5926)
* issue 5924 - ASAN server build crash when looping opening/closing connections
Issue: Got a crash due to:
1. Failure to get a connection slot because connection freelist is misshandled.
2. A confusion between listening and acceptedfd descriptor leaded to
close the listening descriptor while handing the error.
Solution:
Rename clearly the file descriptor variables
Close the accepted file descriptor in error handler
Rewrite the freelist management so that first connection chosen is the last released one.
(Code is simpler, this fix the end of list issue, and it avoid to spread the open connection over too much memory)
Issue: #5924
Reviewed by: @Firstyear, @vashirov, @droideck (Thanks !)
(cherry picked from commit 02d333251419ff3c4d0384595e9fe7ded5bcd8fc)

Subject: [PATCH] Issue 5984 - Crash when paged result search are abandoned
(#5985)
* Issue 5984 - Crash when paged result search are abandoned
Problem:
Fix #4551 has changed the lock that protects the paged result data
within a connection. But the abandon operation attempts to free
the paged search result with the connection lock.
This leads to race condition and double free causing an heap
corruption and a SIGSEGV.
Solution:
- Get a copy of the operation data that needs to be logged.
- Unlock the connection mutex (to avoid deadlock risk)
- Free the paged result while holding the paged result lock.
Issue: 5984
Reviewed by: @tbordaz (Thanks!)
(cherry picked from commit 06bd0862956672eb76276cab5c1dd906fe5a7eec)
