run_external_diff: use an argv_array for the command line

We currently generate the command-line for the external
command using a fixed-length array of size 10. But if there
is a rename, we actually need 11 elements (10 items, plus a
NULL), and end up writing a random NULL onto the stack.

Rather than bump the limit, let's just use an argv_array, which
makes this sort of error impossible.

Makefile: default to -lcurl when no CURL_CONFIG or CURLDIR

The original implementation of CURL_CONFIG support did not match the
original behavior of using -lcurl when CURLDIR was not set. This broke
implementations that were lacking curl-config but did have libcurl
installed along system libraries, such as MSysGit. In other words, the
assumption that curl-config is always installed was incorrect.

Instead, if CURL_CONFIG is empty or returns an empty result (e.g. due
to curl-config being missing), use the old behavior of falling back to
-lcurl.

Merge branch 'jk/external-diff-use-argv-array' (early part)

Crash fix for codepath that miscounted the necessary size for an
array when spawning an external diff program.

  run_external_diff: use an argv_array for the command line
Merge branch 'db/make-with-curl'

It turns out that some platforms do ship without curl-config even
though they build with the hardcoded default -lcurl and rely on it
to work.

t/lib-httpd: check for NO_CURL

We already do this check individually in each of the tests
that includes lib-httpd. Let's factor it out.

There is one test (t5540) that uses lib-httpd but does not
currently do this check. But it actually has a stricter
check which is a superset (it needs all of the requirements
to have built git-http-push, one of which is not setting
NO_CURL), so adding this extra check won't hurt anything.
http: turn off curl signals

Curl sets and clears the handler for SIGALRM, which makes it
incompatible with git's progress code. However, we can ask
curl not to do this.
http: refactor http_request function

This function takes a flag to indicate where the output
should go (either to a file or to a strbuf). This flag is
mostly used to set the callback function we hand to curl.

This isn't very flexible for adding new output types.
Instead, let's just let callers pass in the callback
function directly. This results in shorter, more readable,
and more flexible code.

The only other thing the flag was used for was to set a
"Range" header when we already have a partial file (by using
the results of ftell). This patch also adds an "offset"
parameter, which can be used by callers to specify this
feature separately (which is also more flexible, as non-FILE
callers can now resume partial transfers).
http: add a public function for arbitrary-callback request

The http_request function recently learned to take arbitrary
callbacks; let's expose this functionality to callers.
remote-curl: use http callback for requesting refs

This should behave identically to the current strbuf code,
but opens up room for us to do more clever things with
bundles in a future patch.
