build: replace autotools with cmake

this patch removes all the autoconf/automake/libtool build
infrastructure and replaces it with cmake.

notable default behavior changes:
- man pages are not pre-built, and are not built by default, must be
  enabled with `-DBUILD_MANPAGES=ON`.

removed features:
- srpm packaging, to be reintroduced at some point.
- deb packaging, now handled externally via rafaelmartins/deb.rgm.io

more stuff must be missing, please report bugs!

-# How to release a new blogc version
-
-These are some rough steps required to produce a blogc release.
-
-
-## Define version number
-
-- Read repository logs:
-  ```
-  $ git log v0.18.0..HEAD  # replace with whatever latest release
-  ```
-- Follow this criteria:
-  - Only bug fixes: Bump micro version.
-  - Something new: Bump minor version, set micro to `0`.
-  - We have no plans to change major version so far. Keep it `0`.
-
-
-## Prepare release
-
-- Write blog post (repository is https://github.com/blogc/blogc.rgm.io/)
-  ```
-  $ cp content/news/blogc-0.18.0.txt content/news/blogc-0.19.0.txt  # replace versions
-  $ vim blogcfile  # change LATEST_RELEASE, add new post file to the end of [posts]
-  $ vim content/news/blogc-0.19.0.txt  # write the content, based on what changed. put some placeholder DATE
-  $ blogc-make runserver
-  ```
-- Copy manpage sources from main repository (https://github.com/blogc/blogc):
-  ```
-  $ cp -r ../blogc/man/* man/
-  $ make -C man
-  ```
-  ronn output is not idempotent. It may rewrite HTML for manpages that are unchanged. Make sure to discard these changes somehow with git.
-- Write GitHub release draft. Content is similar to blog post. No need to include lots of links. Always append this to the end of text:
-  ```
-  Please download the custom tarballs, not the files generated automatically by GitHub, they are garbage.
-  ```
-
-
-## Bump version
-
-- Make sure that all the code is in place.
-- Edit `blogc.spec.in`. Check if dependencies and packaging are still correct.
-  - If something needs update, do it. Then commit, push and wait for [CI](https://github.com/blogc/blogc/actions). After successful build, grab a `.src.rpm` from https://distfiles.rgm.io/blogc/LATEST/, upload to a test [Copr](https://copr.fedorainfracloud.org/), wait until it builds and follow also next step.
-  - If everything is ok, add a changelog line to the top of the `%changelog` section.
-- Update debian version:
-  - If something needs update, do it. Then commit, push and wait for [CI](https://github.com/blogc/blogc/actions).
-  - Run `dch`:
-    ```
-    $ dch --distribution unstable --newversion 0.19.0-1~0upstream "Upstream Release"
-    ```
-- Commit, push and wait for [CI](https://github.com/blogc/blogc/actions).
-- Create signed tag:
-  ```
-  $ git tag -s -m 'blogc-0.19.0' v0.19.0  # replace with whatever version you defined before
-  ```
-  This requires my (rafaelmartins) personal GPG key. If someone else needs to publish a release, please announce the new key in the blog post and GitHub release.
-- Push signed tag:
-  ```
-  $ git push origin v0.19.0  # replace with whatever version you defined before
-  ```
-- Wait for [CI](https://github.com/blogc/blogc/actions) to build the release files and push them to https://distfiles.rgm.io/blogc/.
-
-
-## Releasing new version
-
-- Download new release files and sign them:
-  ```
-  $ ./download_release.py
-  ```
-  This requires my (rafaelmartins) personal GPG key to sign files. If someone else needs to publish a release, please edit the script to add new GPG key and announce it in the blog post and GitHub release.
-- Grab files from `releases/0.19.0` (replace version) and upload to GitHub release draft, including `.asc` files. The `.src.rpm` and tarballs with debs can be omited.
-- Publish release on GitHub.
-- Fix blog post DATE, commit and push.
-
-
-## Maintain downstream packages
-- Upload `.src.rpm` file to the [official Copr](https://copr.fedorainfracloud.org/coprs/rafaelmartins/blogc/). The Copr is owned by rafaelmartins, there's no concept of organizations. I believe that an user could request publish access here: https://copr.fedorainfracloud.org/coprs/rafaelmartins/blogc/permissions/
-- Prepare and submit [termux-packages](https://github.com/termux/termux-packages) pull request.
-  - Edit `packages/blogc/build.sh`. Update version.
-  - Try to build package (it will fail):
-    ```
-    $ ./scripts/run-docker.sh ./build-package.sh blogc
-    ```
-  - Get new SHA256 hash from last command and update `packages/blogc/build.sh`.
-  - Build package:
-    ```
-    $ ./scripts/run-docker.sh ./build-package.sh blogc
-    ```
-  - If everything builds fine, commit and create pull request.
