MINOR: patch for minor typo (ressources/resources)

The main stats page says "ressources" (French spelling) rather than
"resources" (English spelling).

One little patch attached (against v1.4.20).

Many thanks,

Adrian
MINOR: logformat %st is signed

replace ultoa by ltoa for HTTP status code (can be -1)
BUG/MAJOR: possible crash when using capture headers on TCP frontends

Olufemi Omojola provided a config and a core showing a possible crash
when captures are configured on a TCP-mode frontend which branches to
an HTTP backend. The reason is that being in TCP mode, the frontend
does not allocate capture pools for the request, but the HTTP backend
tries to use them and dies on the NULL.

While such a config has long been unlikely to happen, it looks like
people using websocket tend to do this more often now.

Change the control to use the pointer instead of the number of captures
to know when to log.

This bug was reported in 1.4.20, so it must be backported there.
MINOR: config: disable header captures in TCP mode and complain

In order to help users fix their configs, report a warning when a capture
has been set on a non-HTTP frontend.

This should be backported to 1.4.

Fix: possible segfault with logformat

Possible zero-pointer deference in sess_log().
Checks of return values in sess_log() fix the issue.

Fix bad computation in logformat_write_string().
split of log_format generation

* logformat functions now take a format linked list in arguments
* build_logline() build a logline using a format linked list
* rename LOG_* by LOG_FMT_* in enum
* optimize LOGCHAR(x) macro
* improve error management in build_logline()
