Gentoo Packages

Hi there! I've splitted all the third-party modules out of the NginX ebuild. Since now (>=1.13.6) that modules will be maintained separately. Also, it should be easier to contribute new ones.

Although, you should keep few things in mind:

1) Since now, you *MUST* load all the modules you use.

  As easy option, you can add following command as the first
  line in your nginx.conf file:

      include modules.d/*.conf;

  If you prefer to manually specify only the modules that you're
  really use in your configuration, you can use:

      load modules/[module_name].so;

  directive for that.

2) Some modules (the ones that pathces NginX source to call functions

  from inside themselves, and so *requires* static linking, even
  despite I made them to be a dynamic module) are currently broken.
  (For example, it is 'www-nginx/upstream-check').

  Also, some of such modules can miss some functionality (like the
  support of NginX's internal round-robin upstream) because of the
  same problem.

  Actually, they shouldn't patch nginx sources in the first place.

  But due to their abandonment (having last commits about 4-10 years
  ago), there is nobody to fix that problems.

  I'll try to fix that in the future, but I can't promise anything.

  Anyway, if you have any problems - feel free to post the issue on
  GitHub or write me an email.
