string-list API: change "nr" and "alloc" to "size_t"
Change the "nr" and "alloc" members of "struct string_list" to use "size_t" instead of "nr". On some platforms the size of an "unsigned int" will be smaller than a "size_t", e.g. a 32 bit unsigned v.s. 64 bit unsigned. As "struct string_list" is a generic API we use in a lot of places this might cause overflows. As one example: code in "refs.c" keeps track of the number of refs with a "size_t", and auxiliary code in builtin/remote.c in get_ref_states() appends those to a "struct string_list". While we're at it split the "nr" and "alloc" in string-list.h across two lines, which is the case for most such struct member declarations (e.g. in "strbuf.h" and "strvec.h"). Changing e.g. "int i" to "size_t i" in run_and_feed_hook() isn't strictly necessary, and there are a lot more cases where we'll use a local "int", "unsigned int" etc. variable derived from the "nr" in the "struct string_list". But in that case as well as add_wrapped_shortlog_msg() in builtin/shortlog.c we need to adjust the printf format referring to "nr" anyway, so let's also change the other variables referring to it.
