This adds subdirectories of `share/emacs/site-lisp/` in every path in
`NIX_PROFILES` to `load-path` to allow loading of more complex
libraries like `mu4e`.
Fixes #33412
`site-start.el` is the file loaded on startup, containing nix-specific
customizations like adding paths in `NIX_PROFILES` to the
emacs-specific search-path (`load-path`) or making man-pages in these
directories discoverable.
This reduces the closure size of Emacs from 575 to 279 MiB. Dumping
Emacs had a chance of leaking parts of the environment (such as $PATH)
into the dumped executable. This hopefully fixes it. (It's a bit hard
to tell since the effect is not deterministic.)

Previously, emacs-macport was giving the error:
- AppKit/AppKit.h: present but cannot be compiled
- Carbon/Carbon.h: present but cannot be compiled
This add "MAC_OS_X_VERSION_MIN_REQUIRED=1090" to CFLAGS to allow them
to compile with the new 10.10 headers.
Fixes #20682.
Install the source files, and the associated TAGS files. Use
.dir-locals.el to select the TAGS file automatically.
Turn the option on by default, to get a consistent behavior when using
xref-find-definitions (M-.), whether looking for an elisp (e.g. defun)
or a C (e.g. defalias) definition.
This commit removes all references to emacs24 with the exception of
emacs24-macports. The two folders in `pkgs/applications/editors` named
`emacs-24` and `emacs-24` are consolidated to a new `emacs` folder.
Various parts in nixpkgs also referenced `emacs24Packages` (pinned to
`emacs24`) explicitly where `emacsPackages` (non-pinned) is more
appropriate. These references get fixed by this commit too.

(set-default-font "Bitstream Vera Sans Mono-8")
to ~/.emacs to get a TTF font.
