After some profiling, it turns out map-put and map-delete are 5-7x
slower (more on Emacs 25) than delq, setf/alist-get and add-to-list for
small lists (under 250 items), which is exactly how I've been using
them.
The only caveat is alist-get's signature is different on Emacs 25, thus
a polyfill is necessary in core-lib.
Initialize it globally and turn it off where needed, instead of enabling
it on demand. Also fixes void-function: flycheck-mode errors when
:feature syntax-checker is disabled. This is experimental.
Indirectly fixes#710
In later versions of Emacs, if a var alias is created *after* it has
been assigned a value, an error is thrown. This prevents the user from
opening js files.

I am slowly phasing out the setting system (def-setting! and set!),
starting with these.
What are autodefs? These are functions that are always defined, whether
or not their respective modules are enabled. However, when their modules
are disabled, they are replaced with macros that no-op and don't
waste time evaluating their arguments.
The old set! function will still work, for a while.
load!'s first argument is no longer a symbol (that will cause
void-variable errors now) to save on unnecessary interning and simplify
compile-time logic. It accepts any valid form that evaluates to a string
now.
If you use load!, you need to change its argument to a string!
e.g. (load! +my-module) => (load! "+my-module")
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.
Much of this config is done in package autoloads, and now that
auto-mode-alist is cached in doom-package-alist (after reading autoload
files), we can save some space by removing redundant config.
+ No need for some rjsx-mode hooks, when it is derived from js2-mode
(thus, js2-mode hooks will run in rjsx-mode).
+ Reorganized package configs with major modes at the top.
+ Fix incorrect usage of add-hook! with three arguments for rjsx-mode.
