7365f7d41b CLEANUP: proto_http: few corrections for gcc warnings.
first, we modify the signatures of http_msg_forward_body and
http_msg_forward_chunked_body as they are declared as inline
below. Secondly, just verify the returns of the chunk initialization
which holds the Authorization Method (althought it is unlikely to fail  ...).
Both from gcc warnings.

060e57301d BUG/MINOR: dns: trigger a DNS query type change on resolution timeout
After Cedric Jeanneret reported an issue with HAProxy and DNS resolution
when multiple servers are in use, I saw that the implementation of DNS
query type update on resolution timeout was not implemented, even if it
is documented.

9f72a39f68 DOC: fix "needed" typo
While at it use "You" instead of "They" as in the context
it seems to make more sense to refer to "you", as it is
you that are going to be running the command, there is no
"they".

02779b6263 CLEANUP: uniformize last argument of malloc/calloc
Instead of repeating the type of the LHS argument (sizeof(struct ...))
in calls to malloc/calloc, we directly use the pointer
name (sizeof(*...)). The following Coccinelle patch was used:

@@
type T;
T *x;
@@

  x = malloc(
- sizeof(T)
+ sizeof(*x)
  )

@@
type T;
T *x;
@@

  x = calloc(1,
- sizeof(T)
+ sizeof(*x)
  )

When the LHS is not just a variable name, no change is made. Moreover,
the following patch was used to ensure that "1" is consistently used as
a first argument of calloc, not the last one:

@@
@@

  calloc(
+ 1,
  ...
- ,1

3c2f2f207f CLEANUP: remove unneeded casts
In C89, "void *" is automatically promoted to any pointer type. Casting
the result of malloc/calloc to the type of the LHS variable is therefore
unneeded.

Most of this patch was built using this Coccinelle patch:

@@
type T;
@@

- (T *)
  (\(lua_touserdata\|malloc\|calloc\|SSL_get_app_data\|hlua_checkudata\|lua_newuserdata\)(...))

@@
type T;
T *x;
void *data;
@@

  x =
- (T *)
  data

@@
type T;
T *x;
T *data;
@@

  x =
- (T *)
  data

Unfortunately, either Coccinelle or I is too limited to detect situation
where a complex RHS expression is of type "void *" and therefore casting
is not needed. Those cases were manually examined and corrected.

f3764b7993 MEDIUM: proxy: use dynamic allocation for error dumps
There are two issues with error captures. The first one is that the
capture size is still hard-coded to BUFSIZE regardless of any possible
tune.bufsize setting and of the fact that frontends only capture request
errors and that backends only capture response errors. The second is that
captures are allocated in both directions for all proxies, which start to
count a lot in configs using thousands of proxies.

This patch changes this so that error captures are allocated only when
needed, and of the proper size. It also refrains from dumping a buffer
that was not allocated, which still allows to emit all relevant info
such as flags and HTTP states. This way it is possible to save up to
32 kB of RAM per proxy in the default configuration.

40e1d51068 BUG/MEDIUM: stick-tables: some sample-fetch doesn't work in the connection state.
The sc_* sample fetch can work without the struct strm, because the
tracked counters are also stored in the session. So, this patchs
removes the check for the strm existance.

This bug is recent and was introduced in 1.7-dev2 by commit 6204cd9
("BUG/MAJOR: vars: always retrieve the stream and session from the sample")

This bugfix must be backported in 1.6.

The frequency counters's window start is sent as "now - freq.date",
which is a positive age compared to the current date. But on receipt,
this age was added to the current date instead of subtracted. So
since the date was always in the future, they were always expired if
the activity changed side in less than the counter's measuring period
(eg: 10s).
