Use alloca_{rawbytes,ibytes} in #'copy-file, #'insert-file-contents-internal
src/ChangeLog addition:
2014-01-20 Aidan Kehoe <kehoea@parhasard.net>
* fileio.c (Fcopy_file, Finsert_file_contents_internal):
Use alloca_{rawbytes,ibytes} here instead of the implicit alloca
on the stack; doesn't change where the buffers are allocated for
these two functions, but does mean that decisions about alloca
vs. malloc based on buffer size are made in the same place
(ultimately, the ALLOCA() macro).
