[ChangeLog]

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]
Malloc failure behavior now depends on size of allocation.
* alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
* lisp.h: Change signatures accordingly.
* alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
All callers changed.
