BREAKING CHANGE: Racer is no longer developed and its project page
recommends using rust-analyzer instead. Moreover, users have reported
issues trying to build/install it on recent versions of rust, so I've
removed support for Racer from Doom, and now default solely to LSP for
IDE features.
Users that want these features will need to activate the module's +lsp
flag (along with the :tools lsp module) and install rust-analyzer. See
the module's README for instructions.

The documentation claimed that epdinfo will be built as soon as a pdf
file is opened. However, support for automatically building epdfinfo was
removed in the commit referenced below.

If doom-emacs-dir contains a "~", attempting to call `git -C` will fail
with an error like:
fatal: cannot change to '~/.config/emacs/': No such file or directory
Fix this by canonicalizing the filename.
I prefer to be more explicit about these variables' defaults, then to
rely on proper load order and unverified global state to ensure they're
properly set.
BREAKING CHANGE: This finally removes 'doom refresh'. It was first
deprecated in 8a77633 and disabled in 8c37928, and has long since been
replaced with 'doom sync'.

And emit more informative errors if they fail.
This eval-when-compile approach is used in preparation for v3, where
Doom's core libraries will be byte-compiled.
This was done to purge superfluous files from Doom's project structure
and simplify its entry points. And with early-init.el now acting as
Doom's universal bootstrapper (see c05e615), we don't have enough
bootstrap logic to warrant being its own file.
Also removes the redundant version check, given doom.el is assured to be
loaded before doom-cli, and performs its own check.

A concise alternative to the file IO elisp idioms we're used to,
involving some combination of with-temp-file, with-temp-buffer,
insert-file-contents, coding-system-for-{read,write}, write-region, read
loops, print-to-current-buffer loops, etc.
These were engineered to make reading/writing text and lisp data from/to
files simpler, and will be used extensively in the v3 CLI.
Consecutive expand-file-name and recursive apply's can be expensive, so
the function has been simplified to rely more on file-name-concat. This
does change one trait about it, however: absolute paths in SEGMENTS no
long reroot the whole path, and are concatenated as ordinary file
segments.
The performance benefit is more pronounced on Emacs 28+, and will be
even more so when Doom later starts byte-compiling its libraries.
These two files were removed in ccb5fde9bcc on the rewrite-docs branch,
which was merged in 1f8bf7accb. I planned to add their rewritten
versions soon after, but life and distractions got in the way, so I'm
restoring the old ones until I finish the new ones.

There are two issues here.
1. Projectile uses file-remote-p to check for remote (tramp) paths in
its known project list, when it automatically cleans it up on
projectile-mode's activation. This causes tramp.el to be loaded,
which is expensive.
2. file-remote-p relies on an entry in file-name-handler-alist
(autoloaded by tramp.el) to detect remote paths, which causes tramp
to be loaded. However, Doom sets file-name-handler-alist to nil at
startup for a noteable boost in startup performance.
Normally, this is not an issue, as I defer projectile-mode until well
after file-name-handler-alist is restored, but it is trivial for a
user to inadvertantly load it too early (often as part of another
package that depends on it, or by blindly following projectile's
install instructions and calling projectile-mode themselves).
In order to address both of these, I defer projectile's cleanup process
altogether. Another approach I considered was to ensure projectile-mode
wasn't activated until the right time, regardless of when projectile is
loaded, but this may trouble savvier Emacs users who need projectile's
API early during startup, so it needs more consideration.

This centralizes Doom's core startup optimizations and, as a
side-effect, reduces the runtime of bin/doom commands substantially.
This also simplifies the user story for loading Doom remotely (for batch
sessions or doomscripts).
Rather than impose a 10-45min compilation step on users, I've disabled
ahead-of-time compilation for deferred compilation. In exchange, it will
eat up some CPU time the first time each uncompiled package is loaded,
but as this happens asynchronously (and are then quietly loaded in the
background), I think this is acceptable.
An --aot switch (or similar) will be added to `doom sync` and `doom
build` in the future, in case folks prefer the old behavior.
