config-compilation: Warnings and errors when compiling files

[rye]

On startup (after applying #136 to fix config compilation), I get the following warnings printed to *config-compilation*:

I think it's worth investigating the "assignment to free variable" errors at least, and I'm going to do some poking around to see if there are any other things we should do. Here's a checklist containing the warnings and errors.

(Some of these may exist only in my configuration; I'll prune down the list as I go through it.)

Actually, no, I don't know if I can do this by just adding calls to require everyhere.

When I do that, the startup time goes up from 2 seconds to nearly 5 seconds (on my machine, which is not the most speedy). This is because the interpreter has to load the entire feature (i.e. the entire package) before it continues, whereas with the existing system, autoloads ensure that the required files are loaded before the symbols are actually used.

I can resolve the config compilation warnings, at least, by adding (eval-when-compile (require '<package>)) lines to the files. Sometimes, autoloads aren't fully generated, so we have to add custom (autoload) lines. (This usually happens when packages are grouped together like magit and magit-popup, where magit depends on symbols from magit-popup.) On my working branch, I've only had to do this once or twice for a few odd packages.

A style question, then: do we want to have everything loaded up and ready to go at startup, or would we rather have a slight overhead at the time of buffer creation for features that haven't yet been loaded? (For example, when loading your first sh-mode buffer, you have to load and valuate the customizations for sh-mode which requires autoloading.) Personally I really like just loading everything up and being ready after startup.
