To make these errors more consistent with similar commands/operations,
as well as rely less on cl-check-type (cl-lib's understanding of the
`font` type is a bit odd; they'd emit warnings/errors about this, but
still perform the checks -- I opted to check more explicitly instead).
BREAKING CHANGE: This restructures the project in preparation for Doom
to be split into two repos. Users that have reconfigured Doom's CLI
stand a good chance of seeing breakage, especially if they've referred
to any core-* feature, e.g.
(after! core-cli-ci ...)
To fix it, simply s/core-/doom-/, i.e.
(after! doom-cli-ci ...)
What this commit specifically changes is:
- Renames all core features from core-* to doom-*
- Moves core/core-* -> lisp/doom-*
- Moves core/autoloads/* -> lisp/lib/*
- Moves core/templates -> templates/
