Prevent recursive includes of keymap components - Add check for recursive includes of keymap components. It relies on limiting the include depth. The threshold is currently to 15, which seems reasonable with plenty of margin for keymaps in the wild. - Add corresponding new log message `recursive-include`. - Add tests for recursive includes.

decimal integer: 1, 123, etc.
decimal floating-point number: 1.23, etc.
hexadecimal integer: prefixed with “0x”: 0x123, 0xff, 0xAB, etc.

xkbcommon replaces keysyms it does not recognize by the keysym `NoSymbol`.

You may find the list of supported keysyms in
`include/xkbcommon/xkbcommon-keysyms.h`.


#### Examples

<details>
  <summary>Unrecognized keysym “`coma`”</summary>

**Error message:**

```
xkbcommon: WARNING: [XKB-107] de:31:20: unrecognized keysym "coma"
```

xkbcommon does not recognize the keysym “`coma`”. It is most probably
a typo for “<code>com<em>m</em>a</code>”.
See: `XKB_KEY_comma` in `include/xkbcommon/xkbcommon-keysyms.h`.

**Fix:**
  <div class="example-container">
    <div class="example">
      <div class="example-inner">

</dl>

When using an include statement, the included file may contains multiple sections.
The include statement may specify the name of the section to include, or leave it
unspecified. In the latter case, the included file must then define a *default* section.
The present warning is shown when no default section is defined.

To solve this, either fix the include statement by specifying the exact section to
include, or declare a default section in the included file.
