A curious practise seems to have started long ago and contaminated various
code areas, consisting in appending "_pool" at the end of the name of a
given pool. That makes no sense as the name is only used to name the pool
in diags such as "show pools", and since names are truncated there, this
adds some confusion when analysing the dump outputs. Let's just clean all
of them at once. there were essentially in SSL and QUIC.
As reported by Tim in issue #1428, our sources are clean, there are
just a few files with a few rare non-ASCII chars for the paragraph
symbol, a few typos, or in Fred's name. Given that Fred already uses
the non-accentuated form at other places like on the public list,
let's uniformize all this and make sure the code displays equally
everywhere.
This implementation is inspired from Linux kernel circular buffer implementation
(see include/linux/circ-buf.h). Such buffers may be used at the same time both
by writer and reader (lock-free).
