Removes me as Win32 maintainer, because I'm not.

Updates README-WIN32.html to remove my status as a maintainer (I'm not). Also removes ancient porting notes and adds a reference to json_config.h.win32 which is where most folks should go to start with Windows issues.

Also correct a couple of calls to _to_json_string to check the return value.

Adding a file for EditorConfig

Also undo NULL check in json_tokener_set_flags(): it's not at all valid toi
 try to set flags on a NULL pointer, and doing so should not be silently
 ignored.

Minor changes in C source code

Improving README

Improving .gitignore

The test is implied in test1.

The idea is to check that the returned lengths and strings
are identical to what is expected to return the already
tested function 'json_object_to_json_string_ext'.

Also, be sure the right locale_t is freed if we fail on the second uselocale.
Finally, fix test_locale so it *doesn't* use json_object_to_json_string as
 that will simple re-emit the original parsed string values.

This new method allows to also
get the length of the generated string.

initialize null terminator of new printbuf

It's possible (e.g. by using json_object_from_file() on an empty file)
to get json-c to try to use a printbuf that has never had anything
written to it. Before this change, it could access a string that
should be length zero, but was never initialized, and could
theoretically have an unexpected string.

Fix issues with the test script so it works under distcheck too.

linkhash.c: optimised the table_free path

Add tests and descriptions for the functions in json_util.c

To better distinguish between entry->k and entry->v being const within linkhash, but non-const outside, add lh_entry_v() and lh_entry_k() accessors.
Make lh_entry->k const.

Cause README.md to show up in Doxygen output as the main page.

tests/tests1: fix printf format for size_t arguments

Change %d to %llu and add cast to unsigned long long for size_t arguments,
otherwise compilation will fail with errors like:

test1.c:70:15: error: format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘size_t {aka long unsigned int}’ [-Werror=format=]

%zu is avoided to stay compatible with old libc versions (like old Visual
Studio).
