[cmucl-imp] Snapshot 2015-07

[Raymond Toy]

The July snapshot has been tagged, a little bit late.

Binaries will be uploaded soon.  And thanks to Fred Gilham, we'll have
some FreeBSD binaries once again, including the 20f release. (For
FreeBSD 9.3).

Key changes:

 o Some additional functionality moved back to the core unix.lisp from
   the contrib:
   o unix-getenv for asdf.
   o unix-execve and unix-fork for slime.  Thus, slime should work
     without having to (require :unix).
 o *ERROR-PRINT-LINES* increased to 10.
 o Issues fixed:
   o #5: Give better error messages when using T case in CASE.
   o #4: ELT on lists does not signal an error when given invalid
     index.
   o #3: Shadowing compiler macro functions
   o #7: Local functions and get-setf-expansions
