Christopher Faulet 5939925a38 BUG/MEDIUM: stream: Be sure to release allocated captures for TCP streams
All TCP and HTTP captures are stored in 2 arrays, one for the request and
another for the response. In HAPRoxy 1.5, these arrays are part of the HTTP
transaction and thus are released during its cleanup. Because in this version,
the transaction is part of the stream (in 1.5, streams are still called
sessions), the cleanup is always performed, for HTTP and TCP streams.

In HAProxy 1.6, the HTTP transaction was moved out from the stream and is now
dynamically allocated only when required (becaues of an HTTP proxy or an HTTP
sample fetch). In addition, still in 1.6, the captures arrays were moved from
the HTTP transaction to the stream. This way, it is still possible to capture
elements from TCP rules for a full TCP stream. Unfortunately, the release is
still exclusively performed during the HTTP transaction cleanup. Thus, for a TCP
stream where the HTTP transaction is not required, the TCP captures, if any, are
never released.

Now, all captures are released when the stream is freed. This fixes the memory
leak for TCP streams. For streams with an HTTP transaction, the captures are now
released when the transaction is reset and not systematically during its
cleanup.

This patch must be backported as fas as 1.6.

The HAProxy documentation has been split into a number of different files for
ease of use.

Please refer to the following files depending on what you're looking for :

  - INSTALL for instructions on how to build and install HAProxy
  - BRANCHES to understand the project's life cycle and what version to use
  - LICENSE for the project's license
  - CONTRIBUTING for the process to follow to submit contributions

The more detailed documentation is located into the doc/ directory :

  - doc/intro.txt for a quick introduction on HAProxy
  - doc/configuration.txt for the configuration's reference manual
  - doc/lua.txt for the Lua's reference manual
  - doc/SPOE.txt for how to use the SPOE engine
  - doc/network-namespaces.txt for how to use network namespaces under Linux
  - doc/management.txt for the management guide
  - doc/regression-testing.txt for how to use the regression testing suite
