More xmalloc and related cleanup.

* xterm.c:
Omit needless casts involving void * pointers and allocation.
Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
as the former is more robust if P's type is changed.
Prefer xzalloc to xmalloc + memset 0.
Simplify malloc-or-realloc to realloc.
Don't worry about xmalloc returning a null pointer.
Prefer xstrdup to xmalloc + strcpy.
* editfns.c (Fmessage_box): Grow message_text by at least 80 when
growing it.
* keyboard.c (apply_modifiers_uncached): Prefer local array to
alloca of a constant.
