* 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

* test: integration add git cli tests

Extracted form for easing review process and debug #3152

* test: integration add git cli big file commit

* fix:  Don't rewrite key if internal server

* Fixes API-Endpoint release (#3005)

* Using context.ReferencesGitRepo(); doing the same in the PATCH route.

* Add release create, get and update test

* Populate repo indexer in background

* Check if no repos exist

* race cond

* General refactor of the cmd package

* Address breakage in runCreateUser

* Place "common" functions into cmd.go

Now includes all the template hooks in the page, and a detailed
example for the common case of adding an "about" page.

* Remove hardcoded paths to fix randomly failing tests

* Use correct function for merge path

* Replace all ctx.Handle with ctx.ServerError or ctx.NotFound

* Change Handle(403) to NotFound, avoid using macaron's NotFound

These templates add content to the top navbar
and to the repository page.
This way we do not have to copy and modify the whole
template, and re-modify it after upgrading Gitea if
it changes.

Closes #3259
Updates "git" module, for GetFormatPatch

* Handle io.Copy error

The makefile did not download the theme if the directory "themes/gitea"
is there, even if empty.
On a fresh Ubuntu install, curl is not included, so the theme rule fails
just after creating the empty directory. When you try again after
installing curl, the rule is not triggered.

This could also happen if the download fails for other reasons.

This change makes the theme rule depend on the file "theme.toml"
which will be there only after unpacking a successfully downloaded
theme archive.

Pre-existing installs still have it default to off.
This is consistent with OpenID setting.
