[PATCH v2 1/7] remote-curl: pass "struct strvec *" instead of int/char ** pair

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

We'll be changing the "int nr" in the "struct strvec" to "int size_t"
soon, i.e. from signed to unsigned. It will then make sense to use the
"size_t" type for things that mirror that "nr" member.

This sets up that change in remote-curl.c, we'll change the "int i"
here to a "size_t i" in a later commit (let's also split and "err" up
to make that change smaller).

In this case the push() function can just pass the "struct strvec" it
has down to push_dav() and push_git(), in addition make use of
strvec_pushv() in push_dav() instead of looping over the the specs
ourselves. So we can get rid of much of the need for tracking the
"nr", which in the case of push_dav() was already a "size_t".
