Makefile: do not depend on curl-config

MinGW builds of cURL does not ship with curl-config unless built
with the autoconf based build system, which is not the practice
recommended by the documentation. MsysGit has had issues with
binaries of that sort, so it has switched away from autoconf-based
cURL-builds.

Unfortunately, broke pushing over WebDAV on Windows, because
http-push.c depends on cURL's multi-threaded API, which we could
not determine the presence of any more.

Since troublesome curl-versions are ancient, and not even present
in RedHat 5, let's just assume cURL is capable instead of doing a
non-robust check.

Instead, add a check for curl_multi_init to our configure-script,
for those on ancient system. They probably already need to do the
configure-dance anyway.

Config option to disable side-band-64k for transport

Since commit 0c499ea60f the send-pack builtin uses the side-band-64k
capability if advertised by the server.

Unfortunately this breaks pushing over the dump git protocol if used
over a network connection.

The detailed reasons for this breakage are (by courtesy of Jeff Preshing,
quoted from ttps://groups.google.com/d/msg/msysgit/at8D7J-h7mw/eaLujILGUWoJ):
----------------------------------------------------------------------------
MinGW wraps Windows sockets in CRT file descriptors in order to mimic the
functionality of POSIX sockets. This causes msvcrt.dll to treat sockets as
Installable File System (IFS) handles, calling ReadFile, WriteFile,
DuplicateHandle and CloseHandle on them. This approach works well in simple
cases on recent versions of Windows, but does not support all usage patterns.
In particular, using this approach, any attempt to read & write concurrently
on the same socket (from one or more processes) will deadlock in a scenario
where the read waits for a response from the server which is only invoked after
the write. This is what send_pack currently attempts to do in the use_sideband
codepath.
----------------------------------------------------------------------------

The new config option "sendpack.sideband" allows to override the side-band-64k
capability of the server, and thus makes the dump git protocol work.

Other transportation methods like ssh and http/https still benefit from
the sideband channel, therefore the default value of "sendpack.sideband"
is still true.

config.c: mark die_bad_number as NORETURN

This can help avoid -Wuninitialized false positives in
git_config_int and git_config_ulong, as the compiler now
knows that we do not return "ret" if we hit the error
codepath.
