This prevents emacs-lisp-mode-hook from being run everytime an
autoload file is generated, which can account for a fraction of
package installation time depending on the hooks the user has
configured.
* lisp/emacs-lisp/bytecomp.el (byte-compile-file): Use delay-mode-hooks.
* lisp/emacs-lisp/autoload.el (autoload-find-file)
(autoload-find-generated-file): Use delay-mode-hooks.
(package--silence): New variable.
(package--message): New function.
(package-import-keyring, package-refresh-contents)
(package-compute-transaction, package-install, package-delete)
(package-menu--perform-transaction, package-menu-execute): Use it.
(package--ensure-init-file): Check file contents before visiting.
(package-initialize): Call it.
(package-install-from-buffer, package-install): Don't call it.
(package-menu--list-to-prompt): New function.
(package-menu--prompt-transaction-p): Use "Upgrade" to make the
package-menu-execute prompt less verbose.
Most install/delete logic is now in
`package-menu--perform-transaction', and this function is called
asynchronously if `package-menu-async' is non-nil.
(package-menu-async): New variable. Controls whether
`list-packages' is asynchronous.
(list-packages): Now asynchronous by default.
(package-menu--new-package-list): Always buffer-local.
(package-menu--post-refresh)
(package-menu--find-and-notify-upgrades)
(package-menu--populate-new-package-list): New functions.
(package--with-work-buffer-async)
(package--check-signature-content)
(package--update-downloads-in-progress): New functions.
(package--check-signature, package--download-one-archive)
(package--download-and-read-archives, package-refresh-contents):
Optional arguments for async usage.
(package--post-download-archives-hook): New variable. Hook run
after every refresh.
* lisp/jit-lock.el (jit-lock--run-functions): New function.
(jit-lock-fontify-now): Use it. Handle fontification bounds more
precisely in case the backend functions fontify more than requested.
Don't round up to whole lines since that shouldn't be needed
any more.
* lisp/font-lock.el (font-lock-fontify-region-function): Adjust docstring.
(font-lock-inhibit-thing-lock): Make obsolete.
(font-lock-default-fontify-region): Return the bounds actually used.
* lisp/emacs-lisp/eieio-base.el (eieio-persistent-validate/fix-slot-value):
Fix compilation error.
* lisp/emacs-lisp/cl-macs.el (cl-dolist, cl-dotimes): Silence byte-compiler.
* lisp/emacs-lisp/eieio.el (defclass): Change internal name so as to make
sure only EIEIO files should have "eieio--" prefixes in their .elc.
* lisp/emacs-lisp/cl-macs.el (cl-struct): New pcase pattern.
* lisp/emacs-lisp/eieio.el (eieio-pcase-slot-index-table)
(eieio-pcase-slot-index-from-index-table): New functions.
(eieio): New pcase pattern.
* lisp/emacs-lisp/pcase.el (pcase--make-docstring): New function.
(pcase): Use it to build the docstring.
(pcase-defmacro): Make sure the macro is lazy-loaded.
(\`): Move its docstring from `pcase'.
lisp/emacs-lisp/tabulated-list.el (tabulated-list-print): Only call
`recenter' if `current-buffer' is equal to `window-buffer'.
