Krzysztof Piotr Oledzki 2c6962c3c0 [MAJOR] proto_uxst rework -> SNMP support
Currently there is a ~16KB limit for a data size passed via unix socket.
It is caused by a trivial bug ttat is going to fixed soon, however
in most cases there is no need to dump a full stats.

This patch makes possible to select a scope of dumped data by extending
current "show stat" to "show stat [<iid> <type> <sid>]":
 - iid is a proxy id, -1 to dump all proxies
 - type selects type of dumpable objects: 1 for frontend, 2 for backend, 4 for
   server, -1 for all types. Values can be ORed, for example:
     1+2=3   -> frontend+backend.
     1+2+4=7 -> frontend+backend+server.
 - sid is a service id, -1 to dump everything from the selected proxy.

To do this I implemented a new session flag (SN_STAT_BOUND), added three
variables in data_ctx.stats (iid, type, sid), modified dumpstats.c and
completely revorked the process_uxst_stats: now it waits for a "\n"
terminated string, splits args and uses them. BTW: It should be quite easy
to add new commands, for example to enable/disable servers, the only problem
I can see is a not very lucky config name (*stats* socket). :|

During the work I also fixed two bug:
 - s->flags were not initialized for proto_uxst
 - missing comma if throttling not enabled (caused by a stupid change in
     "Implement persistent id for proxies and servers")

Other changes:
 - No more magic type valuse, use STATS_TYPE_FE/STATS_TYPE_BE/STATS_TYPE_SV
 - Don't memset full s->data_ctx (it was clearing s->data_ctx.stats.{iid/type/sid},
    instead initialize stats.sv & stats.sv_st (stats.px and stats.px_st were already
    initialized)

With all that changes it was extremely easy to write a short perl plugin
for a perl-enabled net-snmp (also included in this patch).

29385 is my PEN (Private Enterprise Number) and I'm willing to donate
the SNMPv2-SMI::enterprises.29385.106.* OIDs for HAProxy if there
is nothing assigned already.
