Add make_vector and make_nil_vector

This makes the callers a bit easier to read, and doubtless
improves efficiency very slightly.  It also simplifies
possible future changes to allow bignum indexes to buffers.
* src/alloc.c (allocate_vectorlike):
Prefer ptrdiff_t to size_t when either will do.
(make_vector): New function.
(Fmake_vector): Use it.
* src/buffer.c (syms_of_buffer):
* src/bytecode.c (syms_of_bytecode):
* src/category.c (Fmake_category_table, init_category_once):
* src/ccl.c (syms_of_ccl):

* src/xfont.c (syms_of_xfont):

* src/lread.c (init_obarray):
* src/profiler.c (make_log, Fprofiler_cpu_log):
* src/term.c (term_get_fkeys_1):
Prefer make_vector (N, V) to Fmake_vector (make_fixnum (N), V).
* src/font.c (build_style_table):
* src/macfont.m (macfont_shape):
* src/process.c (conv_sockaddr_to_lisp, network_interface_info):
Prefer make_uninit_vector if the vector will be initialized soon.
