On unpack, one may want to mix `JSON_STRICT` and optional keys by using
a format like `{s:i,s?o!}`. Unfortunately, this fails the stric test
with `-1 object item(s) left unpacked` error when the second key is not
specified.
To fix that, we iter on each key and we check if we have successfully
unpacked them. This is less efficient than the previous method but it
brings correctness.
First, wrap "advapi32.dll" into the TEXT() macro. If UNICODE is defined,
GetModuleHandle() redirects to GetModuleHandleW(), which excepts a wchar_t*
UTF-16 parameter, thus causing a compile error. TEXT() prefixes the string
literal with L in this case, and does nothing otherwise.
Second, make sure that CryptGenRandom() is actually called through the function
pointer retrieved by the call to GetProcAddress() above.
And third, replace _getpid() with the equivalent and more ubiquitous Win32 API
function GetCurrentProcessId(). Since _getpid() is not exported by all C
runtimes on Windows (most notably the Driver Development Kit), using it might
introduce previously unneeded runtime dependencies. GetCurrentProcessId(), on
the other hand, has been available in kernel32.dll since at least Windows 95,
just like the other API functions used in this code (GetModuleHandle() and
GetProcAddress()).
The valgrind tests where not run on the suites.
And valgrind was always returning 0 so set an explicit exit code on exit. I also had forgotten to change the name of TEST_WITH_VALGRIND to JANSSON_TEST_WITH_VALGRIND so that the tests would never use valgrind.
This is because it's really easy to get a name collission if compiling
Jansson as a subproject in a larger CMake project. If one project includes
several subprojects each having their own config.h, this will cause the
wrong file to be loaded.
This will simplify linking against the lib, both from the build-tree and
install-tree from other CMake projects.
CMakes find_package command uses these configs to locate the exported
targets for the library.
* Also changed so that all CMake options for the project are prepended
with JANSSON_ so that there is no ambiguity when including this as a
subdirectory in another CMake project.
