Aurelien DARRAGON b7f8af3ca9 BUG/MINOR: proxy/server: free default-server on deinit
proxy default-server is a specific type of server that is not allocated
using new_server(): it is directly stored within the parent proxy
structure. However, since it may contain some default config options that
may be inherited by regular servers, it is also subject to dynamic members
(strings, structures..) that needs to be deallocated when the parent proxy
is cleaned up.

Unfortunately, srv_drop() may not be used directly from p->defsrv since
this function is meant to be used on regular servers only (those created
using new_server()).

To circumvent this, we're splitting srv_drop() to make a new function
called srv_free_params() that takes care of the member cleaning which
originally takes place in srv_drop(). This function is exposed through
server.h, so it may be called from outside server.c.

Thanks to this, calling srv_free_params(&p->defsrv) from free_proxy()
prevents any memory leaks due to dynamic parameters allocated when
parsing a default-server line from a proxy section.

This partially fixes GH #2173 and may be backported to 2.8.

[While it could also be relevant for other stable versions, the patch
won't apply due to architectural changes / name changes between 2.4 => 2.6
and then 2.6 => 2.8. Considering this is a minor fix that only makes
memory analyzers happy during deinit paths (at least for <= 2.8), it might
not be worth the trouble to backport them any further?]

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
  - doc/peers.txt for the peers protocol reference
  - doc/coding-style.txt for how to adopt HAProxy's coding style
  - doc/internals for developer-specific documentation (not all up to date)
