* Add 'watch-backend'

This leverages `air` to watch the backend files and trigger `make
backend` automatically when they change. It seems to work rather well
together with `watch-frontend`.

Fixes: https://github.com/go-gitea/gitea/issues/12318

* rework docs to a new section for continuous build

* Rework 'make generate-images'

- Remove external dependencies and replace it with a node script that
  does does the same.
- Move detail removal from gitea-sm.png to favicon.png
- Remove favicon.ico and its generation, it is unused and we already serve
  favicon.png in its place.

Introduce 'make svg' which calls a node script that compiles svg files
to `public/img/svg`. These files are vendored to not create a dependency
on Node for the backend build.

On the frontend side, configure webpack using `raw-loader` so SVGs can
be imported as string.

Also moved our existing SVGs to web_src/svg for consistency.

Fixes: https://github.com/go-gitea/gitea/issues/11618

This prevents a potential make errors like "No rule to make sticky.js"
that happens when a file is present from a previous build but is not
generated in the current build. We don't use these module files from
fomantic so it's safe to not depend on them.

Related to: 7761245d08

This saves around 3 MB binary size by not including useless fomantic
files in the build. Also, this allows us to move jQuery into the main
bundle as well which eliminates a few HTTP requests.

Also included are webpack config changes:

- split less and css loaders to speed up compliation
- enable css sourcemaps
- switch css minfier plugin to cssnano-webpack-plugin which works better
  for sourcemaps than the previous plugin

* Switch code editor to Monaco

This switches out CodeMirror for Monaco which is based on the same code
base as VS code and should work pretty similar to it.

It does add a few async chunks, totalling around 10MB to our build. It
currently supports around 65 languages and in the default configuration,
each language would emit one ugly [number].js chunk, so I opted to
combine them all into a single file for now.

CodeMirror is still being used under the hood by SimpleMDE so it can not
be removed yet.

* inline editorconfig, fix diff, use for markdown, remove more dead code

* refactors, remove jquery usage

Better workaround than https://github.com/go-gitea/gitea/issues/10653

seem like we're getting a new Fomantic-UI release anytime soon, so
this patches it after node_modules installation.

- Added 'lint', 'lint-frontend', 'lint-backend' targets
- Added 'lint-frontend', 'lint-backend' ci steps and restructure the
  'compliance' pipeline to have a clear separation between frontend and
  backend and use parallelism where possible. Also, the main build
  pipelines now depend on 'compliance' so they will skip if it fails.
- Added dependencies on ci steps so they skip when 'compliance' fails
- Moved JS linters to devDependencies
- Removed deprecated 'js' and 'css' targets

* Simplify grep regexp to be more compatible

The new expression also works with the BSD implementation of grep. Also,
I believe the expression did not work consistently for all possible
version numers, for example a two digit patch version would not have
been matched.

* Fix quote

* Allow for two and three part version numbers

* Select one, two and three part version numbers, reject amd64

* Also allow one to three parts for node version

* Use JS code to print node verion in correct format

* Avoid grep altogether

* Handle go1.14beta1 as well.

- Use a whitelist-based approach to find *.go files so we can use
  standard find syntax. Also included is a change that files no
  longer pass a leading './' which should help performance further.

- Instead of running `find` multiple times in make because of the
  lazy evaluation, run it only once and add the bindata files when
  the bindata tag is present

This is another huge speedup on my machine of around 2000%.

* Speed up make

- stop `find` from venturing into node_modules and other directories
  that do not contain *.go files
- only run `find` once for *.go files
- move image tempdir generation to that task
- rename GOFILES to GO_SOURCES_OWN for consistency and to indicate that
  vendor files are not included
- pre-resolve FOMANTIC_SOURCES

* exclude more

* Add frontend/backend make targets, fix source release

- Add 'make backend' and 'make frontend' make targets which are used to
  build go and js/css/svg files respectively.

- The 'backend' target can be invoked without requiring Node.js to be
  present on the system if pre-built frontend assets are present like
  in the release source tarballs.

- Fix source releases missing 'dist' folders inside 'node_modules' which
  were erronously excluded from tar.

- Store VERSION in file VERSION for the release tarballs and prefer that
  file over git-derived version.

* fix release task

* fix typo

* fix another typo

- only `mkdir`the dist dirs when they are absent
- add the dist dirs as prereqs so targets like `make release-sources`
  can run standalone

* make: add release-sources

* make: release-sources exclude .git and make_evidence

Write out TAGS to .make_evidence/tags and compare it to the previous
invocation. If they differ, insert the evidence file into the prereqs
of targets that use TAGS. I made it .PHONY so it always builds.

I did not include the prereq on release tasks, asssuming the will always
do a clean build.
