Aurelien DARRAGON c9af6d5414 DEBUG: pollers/fd: add thread id suffix to per-thread memory areas name hints 
Willy reported that since abb8412d2 ("DEBUG: pollers: add name hint for
large memory areas used by pollers") and 22ec2ad8b ("DEBUG: fd: add name
hint for large memory areas") multiple maps with the same name could be
found in /proc/<pid>/maps when haproxy process is started with multiple
threads, which can be annoying.

In fact this happens because some poller and fd-created memory areas are
being created for each available thread, and since the naming was done
using vma_set_name() with the same <type> and <name> inputs, the resulting
name was the same for all threads.

Thanks to the previous commit, we now use vma_set_name_id() for naming
per-thread memory areas so that "-id" prefix is appended after the name
name, where "id" equals to 'tid+1' (to match the thread numbering logic
found in config file or in ha_panic() report),  allowing to easily
identify which haproxy thread owns the map in /proc/<pid>/maps:
