Stefan Monnier d1a7d16f8e * lisp/cedet/{*.el,ede/*.el}: Use lexical-binding
Remove a few redundant `:group` arguments as well.

* lisp/cedet/ede.el: Use lexical-binding.
Don't load `ede/files` at compile-time.
(ede-speedbar): Declare function.
(ede-load-project-file): Allow `rootreturn` to be a reference rather
than a symbol.
(ede-initialize-state-current-buffer): Pass `ROOT` as a reference
rather than a symbol to `ede-directory-get-open-project` and
`ede-load-project-file` so we don't need to make it dynamically scoped.
(ede-flush-deleted-projects): Avoid `add-to-list` on a local var.

* lisp/cedet/ede/files.el: Use lexical-binding.
(ede-directory-get-open-project): Allow `rootreturn` to be a reference
rather than a symbol.
(ede-project-root-directory): Remove unused var `root`.
(ede-expand-filename-impl): Remove unused vars `path` and `proj`.

* lisp/cedet/cedet-idutils.el: Use lexical-binding.
(cedet-idutils-search): Remove always-nil variable `scopeflags`.

* lisp/cedet/data-debug.el: Use lexical-binding.
(data-debug-insert-overlay-button, data-debug-insert-overlay-list-button)
(data-debug-insert-buffer-button, data-debug-insert-buffer-list-button)
(data-debug-insert-process-button): Remove always-nil variable `tip`.
(data-debug-insert-ring-button): Remove unused var `ringthing`.
(data-debug-insert-widget-properties): Remove unused var `type`.

* lisp/cedet/semantic.el: Use lexical-binding.
(semantic-mode): Strength-reduce `eval` to `symbol-value`.

* lisp/cedet/ede/custom.el: Use lexical-binding.
(ede-project-sort-targets): Remove unused vars `count`, `current`, and
`order`.

* lisp/cedet/ede/pconf.el: Use lexical-binding.
(ede-proj-configure-synchronize): Remove unused var `add-missing`.

* lisp/cedet/ede/pmake.el (ede-proj-makefile-garbage-patterns):
Simplify via η-reduction.
(ede-proj-makefile-dependencies): Use `seq-some` rather than `eval+or`.

* lisp/cedet/ede/proj-elisp.el: Use lexical-binding.
(project-compile-target): Remove unused var `elc`.
(ede-update-version-in-source): Remove unused var `match`.
(project-compile-target): Declare function `cedet-update-autoloads`
from file we don't have.
