cc05fba613 [BUG] definitely fix regparm issues between haproxy core and ebtree
It's a pain to enable regparm because ebtree is built in its corner
and does not depend on the rest of the config. This causes no problem
except that if the regparm settings are not exactly similar, then we
can get inconsistent function interfaces and crashes.

One solution realized in this patch consists in externalizing all
compiler settings and changing CONFIG_XXX_REGPARM into CONFIG_REGPARM
so that we ensure that any sub-component uses the same setting. Since
ebtree used a value here and not a boolean, haproxy's config has been
set to use a number too. Both haproxy's core and ebtree currently use
the same copy of the compiler.h file. That way we don't have any issue
anymore when one setting changes somewhere.

75cf17ee30 [OPTIM] force inlining of large functions with gcc >= 3
GCC 3 and above do not inline large functions, which is a problem
with ebtree where most core functions are inlined.

This simple patch has both reduced code size and increased speed.
It should be back-ported to ebtree.

61eadc028f [BUG] regparm is broken on gcc < 3
Gcc < 3 does not consider regparm declarations for function pointers.
This causes big trouble at least with pollers (and with any function
pointer after all). Disable CONFIG_HAP_USE_REGPARM for gcc < 3.

50e608d721 [MEDIUM] implement memory pools version 2
The new pools know about their size and usage. Malloc is not used
anymore, instead a dedicated function to refill the entries is used.

390223bc32 [BUILD] only enable regparm on x86 to avoid useless warnings
It complains at least on Solaris/sparc64 and OpenBSD/vax.

fb278677e2 [MEDIUM] use regparm on a few tv_* functions
Some of the tv_* functions are called very often. Passing their
arguments as registers is quite faster. This can be disabled
by setting CONFIG_HAP_DISABLE_REGPARM.

2a429503e0 [MINOR] turn every FD_* into functions
On recent CPUs, functions are about twice as fast as inline FD_*, so
there is now a #define CONFIG_HAP_INLINE_FD_SET to choose between the
two modes.
