Remove `docwriter' source (now a pip package).

`docwriter' can now be found at

  https://github.com/freetype/docwriter

The PyPI project is published at

  https://pypi.org/project/docwriter/

Development will continue on the GitHub repository.

* src/tools/docwriter: Remove this folder and its contents from the
repository.

-# FreeType Docwriter
-
-Markdown documentation generator for the FreeType library.
-
-## Setup Instructions
-
-1.  Clone this repository.
-2.  Clone the freetype2 repository from [here](http://git.savannah.gnu.org/cgit/freetype/freetype2.git/).
-3.  Convert the `include/` folder to markdown using the 
-    [freetype-docs](https://github.com/nikramakrishnan/freetype-docs/tree/markdown) repository.
-5.  Copy files from `include_mark/`.
-6.  Run:
-
-    ```bash
-    python -B docwriter.py --prefix=ft2 --title=FreeType-2.9.1 --output=./docs/reference \
-    ./include_mark/freetype/*.h ./include_mark/freetype/config/*.h ./include_mark/freetype/cache/*.h
-    ```
-
-## Usage Information
-
-```
-docwriter [-h] [-t T] -o DIR [-p PRE] [-q | -v] files [files ...]
-
-DocWriter Usage information
-
-positional arguments:
-  files                 list of source files to parse, wildcards are allowed
-
-optional arguments:
-  -h, --help            show this help message and exit
-  -t T, --title T       set project title, as in '-t "My Project"'
-  -o DIR, --output DIR  set output directory, as in '-o mydir'
-  -p PRE, --prefix PRE  set documentation prefix, as in '-p ft2'
-  -q, --quiet           run quietly, show only errors
-  -v, --verbose         increase output verbosity
-```
-
-## Running Tests
-
-There are two possible test scenarios:
-
-1. Running tests on both py27 and py36 (using tox - requires both python versions installed).
-2. Running tests on the currently installed Python version.
-
-They are detailed below.
-
-### Test using Tox
-
-To test on both py27 and py36:
-
-1.  Make sure `tox` is installed:
-    ```bash
-    pip install tox
-    ```
-
-2.  Ensure both py27 and py36 are installed.
-
-3.  Run tests:
-    ```bash
-    tox
-    ```
-
-### Test on single python version
-
-To test on current python version using pytest:
-
-1.  Make sure `pytest` is installed:
-    ```bash
-    pip install pytest
-    ```
-
-2.  Run tests:
-    ```bash
-    python -m pytest
-    ```

-## License
-
-This library is licensed under the [FreeType License](https://www.freetype.org/license.html).
-
-## History
-
-This library was originally written by David Turner as `docmaker` which collected and presented
-documentation in HTML. It has since been modified multiple times, including a major refactor
-to allow multiple output formats. The current `docwriter` is the biggest rewrite, with lots of
-changes, additions etc. that allow it to be more flexible, readable, maintainable and usable.

-You need to sub-class it to output anything sensible.  For example, the

-##  SOURCE BLOCK FORMAT CLASS
-##
-##  A simple class containing compiled regular expressions to detect
-##  potential documentation format block comments within C source code.
-##
-##  The `column' pattern must contain a group to `unbox' the content of
-##  documentation comment blocks.
-##
-##  Later on, paragraphs are converted to long lines, which simplifies the
-##  regular expressions that act upon the text.
