Major optimization refactor, across the board + enable lexical-scope everywhere (lexical-binding = t): ~5-10% faster startup; ~5-20% general boost + reduce consing, function calls & garbage collection by preferring cl-loop & dolist over lambda closures (for mapc[ar], add-hook, and various cl-lib filter/map/reduce functions) -- where possible + prefer functions with dedicated opcodes, like assq (see byte-defop's in bytecomp.el for more) + prefer pcase & cond (faster) over cl-case + general refactor for code readability + ensure naming & style conventions are adhered to + appease byte-compiler by marking unused variables with underscore + defer minor mode activation to after-init, emacs-startup or window-setup hooks; a customization opportunity for users + ensures custom functionality won't interfere with startup.

Reduce list of root files projectile searches for And define them on a per-module basis. This reduces the number of file checks it performs, particularly for non-project files. Might help #1317

Major refactor & optimization of how modules load their packages Now that we are loading package autoloads files (as part of the generated doom-package-autoload-file when running make autoloads), many :commands properties are redundant. In fact, many def-package! blocks are redundant. In some cases, we can do without a config.el file entirely, and can move into the autoloads file or rely entirely on package autoloads. Also, many settings have been moved in their module's autoloads files, which makes them available ASAP; their use no longer depends on module load order. This gained me a modest ~10% boost in startup speed.

:boom: Rename def-package! -> use-package! Calling this pivotal macro "def-package!" has frequently been a source of confusion. It is a thin wrapper around use-package, and it should be obvious that it is so. For this reason, and to match the naming convention used with other convenience macros/wrappers, it is now use-package!. Also changes def-package-hook! -> use-package-hook! The old macros are now marked obsolete and will be removed when straight integration is merged.
