Some missing modules have been added and some others have been updated. The
list is now sorted. It is a bit easier to find something. In addition the
path of files have been updated to reflect recent changes.
William Dauchy and Christopher Faulet are the official maintainers of the
Prometheus exporter. William better knows the Prometheus usages and is the
referent for the features while Christopher's role is more code-centric, he
takes care of bugs and the exporter integration into Haproxy.
This splits the hathreads.h file into types+macros and functions. Given
that most users of this file used to include it only to get the definition
of THREAD_LOCAL and MAXTHREADS, the bare minimum was placed into thread-t.h
(i.e. types and macros).
All the thread management was left to haproxy/thread.h. It's worth noting
the drop of the trailing "s" in the name, to remove the permanent confusion
that arises between this one and the system implementation (no "s") and the
makefile's option (no "s").
For consistency, src/hathreads.c was also renamed thread.c.
A number of files were updated to only include thread-t which is the one
they really needed.
Some future improvements are possible like replacing empty inlined
functions with macros for the thread-less case, as building at -O0 disables
inlining and causes these ones to be emitted. But this really is cosmetic.
