Strict mode rejected leading zeros but nothing else about the shape of a
number, so several malformed numbers parsed and were then written back out
verbatim, producing JSON that other parsers reject:
$ echo '[2.e3]' | ./json_parse -s -
[ 2.e3 ]
RFC 8259 requires a mandatory integer part and at least one digit in both the
fraction and the exponent:
number = [ minus ] int [ frac ] [ exp ]
int = zero / ( digit1-9 *DIGIT )
frac = decimal-point 1*DIGIT
exp = e [ minus / plus ] 1*DIGIT
so "1.", "-2.", "2.e3", "2.e+3", "0.e1", "-.123", "1e" and "1e+" are all
invalid. Walk the accumulated text against that grammar instead. The leading
zero rule from the previous check is part of the same walk rather than a
separate test, and its cases keep their coverage.
Only JSON_TOKENER_STRICT is affected; the default tokener stays as lenient as
it was. Measured against JSONTestSuite (318 files): strict mode went from 44
to 37 files accepted that the suite says must be rejected, default mode stayed
at 71, and nothing that must be accepted regressed in either mode.
When the appended data points into the printbuf itself, growing the buffer may invalidate the source pointer before it is copied. Preserve the source offset across realloc and use memmove for internal overlap.
Tests will now be built at `meson test`-time, so there's no cost if the
user isn't going to run them.
This is better than guarding on build type, as distros may want to test production
builds before shipping.

The iterative rewrite in 17328a67 made json_object_put() return 0 for freed scalars, strings and empty containers, contradicting the documented contract in json_object.h. Distinguish "freed" from "still referenced" in _json_object_put_maybe_free() and add regression tests.
This patch fixes the build error with clang-21
tests/test_deep_nesting.c:19:34: error: a function declaration
without a prototype is deprecated in all versions of C

19 | static char *generate_json_string()
by fixing generate_json_string() definition.
It also removes prototypes for static functions that are not needed.
Windows was failing tests due to how the Windows API works with some of the calls used.
When opening and reading a file O_BINARY is needed otherwise it fails for size checks. This is due to how Windows handles newlines and counts between text and binary mode file reads.
Also fixed is the test for /dev/null.
In Windows, this fails, but crashes due to a missing return statement when it cannot open this file.
I also tried telling windows to open the special file NUL, however that leads to a CRT crash later in the test that cannot be stopped and will always fail. Rather than fail a test that Windows will always fail, it has been disabled in that specific case.

Adding meson build files for json-c that work similarly to the cmake build files.
Where it made sense, I reused existing cmake .h.in files or generated entirely from meson.
All tests were done with GCC and Clang in ubuntu 24.04, Windows using MSVC 2022 and Clang-cl from llvm's repo using version 21.1.3
