Taylor Blau cd45bf0f3e strvec: introduce strvec_init_alloc() ...

When the caller knows upfront how many elements will be pushed onto a
`strvec`, it is useful to pre-allocate enough space in the array to fit
that many elements (and one additional slot to store NULL, indicating
the end of the list.)

Introduce `strvec_init_alloc()`, which allocates the backing array large
enough to hold `alloc` elements and the termination marker without
further reallocation. Reimplement `strvec_init()` as a special case of
`strvec_init_alloc()`, namely when `alloc` is zero.
