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).

According to Paul Keusemann in <20070802140358.GA19566@visi.com>, this
feature probably still works as of 2007-08-02.  However, that doesn't seem
reliable since there doesn't seem to be a way to configure it! */
