diffcore-pickaxe doc: document -S and -G properly

The documentation of -S and -G is very sketchy.  Completely rewrite the
sections in Documentation/diff-options.txt and
Documentation/gitdiffcore.txt.

sha1_file: silence sha1_loose_object_info

sha1_object_info() returns -1 (OBJ_BAD) if it cannot find the object
for some reason, which suggests that it wants the _caller_ to report
this error.  However, part of its work happens in
sha1_loose_object_info, which _does_ report errors itself.  This is
doubly strange because:

* packed_object_info(), which is the other half of the duo, does _not_
  report this.

* In the event that an object is packed and pruned while
  sha1_object_info_extended() goes looking for it, we would
  erroneously show the error -- even though the code of the latter
  function purports to handle this case gracefully.

* A caller might invoke sha1_object_info() to find the type of an
  object even if that object is not known to exist.

Silence this error.  The others remain untouched as a corrupt object
is a much more grave error than it merely being absent.

Makefile: Do not use OLD_ICONV on MINGW anymore

We are building libiconv now the same way as upstream MinGW does, so we do
not need OLD_ICONV anymore when compiling Git either in msysGit or
mingwGitDevEnv.

Define NO_GETTEXT for Git for Windows

The dreaded "your vnsprintf is broken (returned -1)" error is back. At
least with the libintl version we have. So for the moment, just work
around the issue by _not_ using gettext.

Ah, I wish that my attempt at implementing a custom strbuf_vaddf() would
not have been brushed aside so rashly. Oh well. Time saved on maintaining
that thing, I guess (although more time went into working around coping
with existing implementations).

msysgit: Add the --large-address-aware linker directive to the makefile.

This has the effect of increasing the address space from 2GB to 4GB under
64-bit Windows, reducing the likelihood of an "out of memory" error when
e.g.  repacking a large repository.  The test suite passes with this
patch, with and without the MEM_TOP_DOWN flag added to all VirtualAlloc
calls.  While this is no guarantee that there are no issues with large
memory support (it could break Git on other setups than mine, for
example), it at least increases the chance that nothing obvious goes wrong
(such as errors introduced by faulty sign extension, say, with ssize_t).

t/README: test_must_fail is for testing Git

When a test wants to make sure there is no <string> in an output
file, we should just say "! grep string output".

"test_must_fail" is there only to test Git command and catch unusual
deaths we know about (e.g. segv) as an error, not as an expected
failure.  "test_must_fail grep string output" is unnecessary, as
we are not making sure the system binaries do not dump core or
anything like that.
