Aurelien DARRAGON 64e0b63442 BUG/MEDIUM: server: invalid address (post)parsing checks 
This bug was introduced with 29b76ca ("BUG/MEDIUM: server/log: "mode log"
after server keyword causes crash ")

Indeed, we cannot safely rely on addr_proto being set when str2sa_range()
returns in parse_server() (even if SRV_PARSE_PARSE_ADDR is set), because
proto lookup might be bypassed when FQDN addresses are involved.

Unfortunately, the above patch wrongly assumed that proto would always
be set when SRV_PARSE_PARSE_ADDR was passed to parse_server() (so when
str2sa_range() was called), resulting in invalid postparsing checks being
performed, which could as well lead to crashes with log backends
("mode log" set) because some postparsing init was skipped as a result of
proto not being set and this wasn't expected later in the init code.

To fix this, we now make use of the previous patch to perform server's
address compatibility checks on hints that are always set when
str2sa_range() succesfully returns.

For log backend, we're also adding a complementary test to check if the
address family is of expected type, else we report an error, plus we're
moving the postinit logic in log api since _srv_check_proxy_mode() is
only meant to check proxy mode compatibility and we were abusing it.

This patch depends on:
 - "MINOR: tools: make str2sa_range() directly return type hints"

No backport required unless 29b76ca gets backported.

README 

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)
