Dr. Chip retired some time ago and is no longer maintaining the netrw
plugin. However as a runtime plugin distributed by Vim, it important to
maintain the netrw plugin in the future and fix bugs as they are
reported.

So, split out the netrw plugin as an additional package, however include
some stubs to make sure the plugin is still loaded by default and the
documentation is accessible as well.

When treesitter is enabled, by default syntax groups are not defined, but these
groups are used to identify where to skip matches in matchit and matchparen.

This patch does three things:
1. If syntax is enabled regardless of treesitter (`vim.bo.syntax='on'`):
   Use original implementation.
2. If treesitter is enabled and syntax is not:
   Match the syntax groups (i.e. `comment\|string`) against treesitter captures
   to check for skipped groups.
3. Add an explicit treesitter syntax for marking captures to skip:
   matchit uses `b:match_skip` to determine what counts as skippable
   Where 's:comment\|string' uses a match of the named syntax groups against
   a regex match of comment\|string, 't:comment\|string' now uses vim regex
   to match against the names of the treesitter capture groups.

Problem:
`termopen` has long been a superficial wrapper around `jobstart`, and
has no real purpose. Also, `vim.system` and `nvim_open_term` presumably
will replace all features of `jobstart` and `termopen`, so centralizing
the logic will help with that.

Solution:
- Introduce `eval/deprecated.c`, where all deprecated eval funcs will live.
- Introduce "term" flag of `jobstart`.
- Deprecate `termopen`.

Problem:  Termdebug: still get E1023 when specifying arguments and using
          a prompt buffer.
Solution: Use empty() instead of len().  Add a test.  Fix wrong order of
          arguments to assert_equal() in Test_termdebug_basic().

Omit the DeleteCommands() change as it isn't really an improvement.
