In subsequent commits, it will be convenient to have a 'const char **'
of hidden refs (matching `transfer.hiderefs`, `uploadpack.hideRefs`,
etc.), instead of a `string_list`.
Convert spots throughout the tree that store the list of hidden refs
from a `string_list` to a `strvec`.
Note that in `parse_hide_refs_config()` there is an ugly const-cast used
to avoid an extra copy of each value before trimming any trailing slash
characters. This could instead be written as:
ref = xstrdup(value);
len = strlen(ref);
while (len && ref[len - 1] == '/')
ref[--len] = '\0';
strvec_push(hide_refs, ref);
free(ref);
but the double-copy (once when calling `xstrdup()`, and another via
`strvec_push()`) is wasteful.
