0.pre7.140:
	merged SB-C-CALL into SB-ALIEN (since the rationale for
		C-CALL being an extension of "basic" SB-ALIEN isn't
		obviously compelling)
	...deleted various notes about the distinction between
		packages at egrep matches to '\<c-call'
	...mentioned the change in the FFI quasichapter of the
		user manual
	...s/c-call/alien/ at matches to 'sb.c-call'
	...remembered to add SB-C-CALL nickname for backwards
		compatibility
	There seems no longer to be any reason that VOID or
		WEAK-POINTER-P needs to be re-exported from SB-KERNEL.
	It doesn't make all that much sense to reexport
		LOAD-FOREIGN and LOAD-1-FOREIGN from SB-EXT.
	Remove the old set-the-cold-package-nickname support from
		set-up-cold-packages.lisp and friends, since it's
		unused and not quite right anyway and much too
		annoying to fix (messing with renaming SB!FOO
		nicknames to SB-FOO nicknames, ick). The SB-FOO
		nickname needed is this backwards compatibility
		hack, and it can be hacked in at init time.
