Fixes: debbugs:11527

* lib/careadlinkat.c, lib/careadlinkat.h, m4/gnulib-common.m4: Merge.

Malloc failure behavior now depends on size of allocation.
* lib/allocator.h (struct allocator.die): New size arg.
* lib/careadlinkat.c (careadlinkat): Pass size to 'die' function.
If the actual problem is an ssize_t limitation, not a size_t or
malloc failure, fail with errno == ENAMETOOLONG instead of calling 'die'.
[src/ChangeLog]

* lisp.h: Change signatures accordingly.
* alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
