For #5172

As we've dropped support for go 1.8 (see 1.5.0 release post),
now we need to ensure that a minimum of go 1.9 builds correctly.

* Add gpg-sign step to drone

* add compressed releases to gpg-sign targets

* Use exclude to simplify file list

drone-plugins/drone-gpgsign#2

Fix all the resting errors to have a valid swagger file.

They are still some warnings but nothing blocking.

Doing so I found that some request still misses son parameters for some POST/PUT/PATCH request. This means the a client generated from the swagger file will not work completely. 

Fix #4088 by activating validation in drone
Should fix #4010.

Needed to access go tool gxz

* Add LDAP service for tests

* Add LDAP login source and test user sign-in

* Add checks to test if user data is correct

* Add LDAP user sync test

* Add failed user sign-in test

* chore: simplify docker build process.

* chore: update docker plugin.

* Update source installation requirements

We require Golang 1.8 since we use `net/url.PathEscape` which was not introduced until then

* Use Golang 1.8 for build and test

If we state Golang 1.8 we should test using that version as well

* Use golang 1.8 only for single build to see if everything compiles

* Change back edge also for commented out sqlite test

* Restore make test target

* make build -> go build

* fix missing drone test on release/*

* remove test coverage on release/*

Otherwise drone may combine the logs

* import docs into main repository

* Use standard lessc and minify CSS using Node.js

This changes the previous nonstandard `lessc` to the official one and
enables CSS minification via the clean-css module.

To build CSS, Node.js is required along with a `npm install` to get the
tools installed locally in node_modules so there is no dependency on
binaries in PATH. Benefits include:

- Allows one to have a standard lessc in PATH.
- Can now use command line switches on lessc.
- Minified CSS brings faster page load times and also has the benefit
  of discouraging contributors from editing CSS directly.

To build CSS, Node.js is required along with a `npm install` to get the
tools installed locally based on the information in `package.json`.

The 'make stylesheet' task was modified to run without condition. This
makes it easier to work on the make task itself without having to delete
files.

Also fixes: https://github.com/go-gitea/gitea/issues/2198

* install node, npm and modules on drone

* .PHONY

* use 'minify' to minify CSS

* add codecov.io service.
