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.

* 'jk/external-diff-use-argv-array' (early part):
  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.

avoid SIGPIPE warnings for aliases

When git executes an alias that specifies an external
command, it will complain if the alias dies due to a signal.
This is usually a good thing, as signal deaths are
unexpected. However, SIGPIPE is not unexpected for many
commands which produce a lot of output; it is intended that
the user closing the pager would kill them them via SIGPIPE.

As a result, the user might see annoying messages in a
scenario like this:

  $ cat ~/.gitconfig
  [alias]
  lgbase = log --some-options
  lg = !git lgbase --more-options
  lg2 = !git lgbase --other-options

  $ git lg -p
  [user hits 'q' to exit pager]
  error: git lgbase --more-options died of signal 13
  fatal: While expanding alias 'lg': 'git lgbase --more-options': Success

Many users won't see this, because we execute the external
command with the shell, and a POSIX shell will silently
rewrite the signal-death exit code into 128+signal, and we
will treat it like a normal exit code. However, this does
not always happen:

  1. If the sub-command does not have shell metacharacters,
     we will skip the shell and exec it directly, getting
     the signal code.

  2. Some shells do not do this rewriting; for example,
     setting SHELL_PATH set to zsh will reveal this problem.

This patch squelches the message, and let's git exit
silently (with the same exit code that a shell would use in
case of a signal).

The first line of the message comes from run-command's
wait_or_whine. To silence that message, we remain quiet
anytime we see SIGPIPE.

The second line comes from handle_alias itself. It calls
die_errno whenever run_command returns a negative value.
However, only -1 indicates a syscall error where errno has
something useful (note that it says the useless "success"
above). Instead, we treat negative returns from run_command
(except for -1) as a normal code to be passed to exit.
