runtime(c): Recognize "__inline" (#14145)
`__inline` is recognized by GCC, and may even be preferred, as MSVC does
not recognize `__inline__`.

* runtime(vim): Update base-syntax, fix escaping :syn and :hi sub-groups

- Remove contained :syntax and :highlight sub-groups from the function
  body cluster.  These should only match in the respective commands.
- Remove vimSynLine syntax group from several clusters.  The definition
  of vimSynLine was removed in Vim 5.3.

* runtime(vim): Update syntax generator, use standard Last Change date format

The de facto standard date format is YYYY MMM DD.

runtime(java): Recognise text blocks (#14128)
Also, accept as valid the space escape sequence `\s`.

Also, consistently use the claimed `javaDebug` prefix for
syntax group definitions kept under `g:java_highlight_debug`.

Since `javaStringError` is commented out for its generality,
let's comment out `javaDebugStringError`, its copy, as well.

runtime(java): Recognise _when_ clauses in _switch_ blocks
Also:

- distinguish _yield_ when used as a contextual keyword from
  when used qualified as a method or a method reference (as
  can be seen in testdir/input/java_switch.java, variables
  and method declarations named _yield_ will be recognised
  as the namesake keyword--consider picking other names for
  variables, and defining g:java_highlight_functions to have
  method names painted; since _yield_ statements can have
  trailing parens, they must be recognised as statements,
  for only qualified _yield_ method calls are supported);

- recognise grouped _default_ _case_ labels;

- describe primitive types for _case_ labels (JLS, §14.11,
  §3.10.1);

- recognise some non-ASCII identifiers (see javaLambdaDef,
  javaUserLabel) (further improvement for better recognition
  of identifiers will be arranged in a separate PR).

Because the arrow '->' is used in two kinds of expressions,
lambda (abstractions) and _switch_, necessary changes were
made for the recognition of either (and further improvement
touching lambda expressions will be separately arranged).

Because 'default' is used for instance method declarations
in interfaces and in _switch_ labels, necessary changes were
made for the recognition of either (and further improvement
touching method declarations will be separately arranged).

Finally, it deemed appropriate to put 'yield' in the syntax
group of javaOperator rather than javaStatement, for its
member 'var' is also another contextual keyword (e.g., this
is valid syntax: "var var = var(test.var);").

References:
https://openjdk.org/jeps/361 (Switch Expressions)
https://openjdk.org/jeps/440 (Record Patterns)
https://openjdk.org/jeps/441 (Pattern Matching for switch)

Also, add a Java specific filetype plugin for the syntax
test, so that no soft-wrapping of long indented lines occur.

Otherwise the syntax scripts would miss a few lines during
scrolling and verification of the screen dumps.

runtime(syntax-tests): simplify code and allow filetype options
The whole testdir/runtest.vim is a bit of a mess. So this is an attempt
to improving the current state. First of all, let's move most of the
code into a single RunTest() function so that it's easier to run this
manually.

Then, let's add the possibility to customize filetype specific tests by
applying filetype specific options. We will make use of it in the next
commit, where the provided java file uses tabs, which cause line
wrapping which will then cause the scrolling to miss some lines when
redrawing (see #14105)

patch 9.1.0122: Some minor issues with the getregion() function
Problem:  Some minor issues with the getregion() function
Solution: Fix examples in the help, use OP_NOP op_type and MBLOCK
          as motion_type in f_getreg(), update vim syntax to
          for getregion() (Maxim Kim)

```
:xnoremap <CR>
\ <Cmd>echow getregion('v', '.', mode())<CR>
```
`echo` while in visual mode has no visible effect, thus people trying
example might be frustrated as it looks like nothing happens.

So the option is to change it to `echow` or `echom`.
With `echom` it is again has no visible effect but one can at least inspect `:messages`.
On the other hand `echow` showes selected text in a popup window.

```
Can also be used as a |method|: >
'.'->getregion("'a', 'v')
```

Here is the typo, which makes example invalid, should be `("'a", ...`

runtime(vim): Distinguish Vim9 constructor definitions from the :new ex command (#14050)
With the arrival of Vim9 classes, the syntax must allow for
_new_ constructors; multiple constructor definitions are
supported for a class, provided distinct suffix-names are
used.  Currently, the defined constructors match either
vimCommand or vimFunctionError (for any newBar).

For example:
------------------------------------------------------------
vim9script

class Foo
    def new()
    enddef

    def newBar()
    enddef
endclass
------------------------------------------------------------

Since every constructor is required to bear a lower-cased
_new_ prefix name, it should suffice to distinguish them
from functions, and so there are no new highlight or syntax
groups introduced.

runtime(vim): Update base-syntax, remove unused vimString region
These were included with the initial release of the syntax file for Vim
5 and were probably intended to allow for syn-region start/skip/end
patterns with a '!' or '+' delimiter.  However, these cases are
currently handled by the vimSynRegPat group.

The removed patterns never match anywhere in the distributed runtime
files and it is believed that this is generally true.

runtime(gpg): Mark dangerous use-embedded-filename with WarningMsg
The syntax highlighter is likely to encourage people to use the listed
commands.

But `use-embedded-filename` is a dangerous option that can cause GnuPG
to write arbitrary data to arbitrary files whenever GnuPG encounters
malicious data.

GnuPG upstream explicitly warns against using this option:

https://dev.gnupg.org/T4500
https://dev.gnupg.org/T6972

However, since this is a valid option, we cannot just drop it from the
syntax script. Instead, let's mark it with the WarningMsg highlighting
to make it obvious, that this option is different (and should not be
used for security reasons).

runtime(dosbatch): improve '::' comment highlighting
Added a syntax region for command blocks so that the highlighting of
`::` comments in them can be controlled.  The `dosbatch_colons_comment`
variable now controls if all `::` comments in a code block are
highlighted as comments or errors.  A `::` comment at the end of a
command block is always highlighted as an error.

This re-enables the highlighting of `::` comments in `.bat` files as
requested in #13666, while allowing control of highlighting them in
command blocks requested in #11778 and first attempted in #11980.

runtime(odin): include ftplugin, syntax and indent script (#13867)
Note for Neovim Contributors: this is bundled as Vim9 Script. If you want to use this on Neovim, you need to convert the Vim9 scripts to Vim Script or Lua or leave it out.

patch 9.1.0030: Cannot use terminal alternate font
Problem:  Cannot use terminal alternate fonts (PMunch)
Solution: Support terminal alternate fonts using
          CSI SGR 10-20 and t_CF code (PMunch)

Add support for alternate font highlighting

This adds support for alternate font highlighting using CSI SGR 10-20.
Few terminals currently support this, but with added tool support this
should improve over time. The change here is more or less taken from how
colors are configured and applied, but there might be some parts I
missed while implementing it. Changing fonts is done through the new
`:hi ctermfont` attribute which takes a number, 0 is the normal font, and
the numbers 1-9 select an "alternative" font. Which fonts are in use is
up to the terminal.
