This uses three methods of obtaining the actual windows version,
RtlGetVersion which is the ntdll version of GetVersionEx that bypasses
the manifest check garbage, looking up the file version of a file that
is most likely to be updated per windows version (ntoskrnl), and the
registry. Of the three values, it chooses the highest windows version
obtained by the three.

Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
Returns the current version number of windows. The lowest byte is the
minor version number, then the next lowest byte is the major version
number. E.g. 0x601 for Windows 7, 0x602 for Windows 8, 0x603 for
Windows 8.1, and 0xA00 for Windows 10.
Caches the frequency of the performance counter. It was supposed to be
caching it already, but it seems that code was unintentionally not
included.

Follow-up to 47aa56b (PR #620). Windows 10 revision detection broke in
Build 15036 (Creators Update) after Revision 296. This aims to further
fix revision detection on Windows 10.
Certain PSAPI functions moved to KERNEL32 after Vista, setting
PSAPI_VERSION 1 uses the old PSAPI exports for compatibility. Vista
support was unintentionally broken by a6318ff.
Allows safely/atomically replacing a file and creating a backup of the
original. The reason for adding this function is because Microsoft
provides a ReplaceFile function which does this in a single call.
Commit aa899c2 (PR #603) added logging for Windows bitness/arch, but it
was a bit incomplete/short-sighted. It only added that information to
the regular logs. This commit makes it easier to retrieve that
information for other purposes, like the crash handler.
Outputting a human-readable error message on library load failure makes
it a little bit easier for plugin developers to determine why a plugin
library may have failed to load (such as missing dependency), rather
than having to look up the error code each time.

SetThreadExecutionState with ES_DISPLAY_REQUIRED has the same effect of preventing the screensaver from activating. Using SPI_SETSCREENSAVEACTIVE leaves the screensaver disabled system-wide if OBS crashes before it can re-enable it.
These fucntions prevent the computer from going to sleep, hibernating,
or starting up a screen saver.
On linux, it will also attempt to use DBus to prevent gnome/kde/etc
sleep, but it's not necessarily required in order to compile the
library. Otherwise, it will simply call "xdg-screensaver reset" once
every 30 seconds to reset the screensaver timer.
Microsoft basically deprecated GetVersion/GetVersionEx, so now you have
to query the file version of kernel32.dll in order to get the actual
windows version. Because of the steps involved in getting the windows
version are fairly complicated, this is an exported libobs helper
function that can be used to get the windows version if needed.
(Microsoft does have its own set of helper functions for this but the
API feels a bit.. awkward, and you can't actually get the real windows
version with them)
Certain plugins/modules that are loaded on windows may be dependent on
libraries that are located in the same directory as the module in
question. This makes is so that LoadLibrary will also search for
dependent libraries for that module in the module's directory.
Changed:
char *os_get_config_path(const char *name);
To:
int os_get_config_path(char *dst, size_t size, const char *name);
Also added:
char *os_get_config_path_ptr(const char *name);
I don't like this function returning an allocation by default.
Similarly to what was done with the wide character conversion functions,
this function now operates on an array argument, and if you really want
to just get a pointer for convenience, you use the *_ptr version of the
function that clearly indicates that it's returning an allocation.
Typedef pointers are unsafe. If you do:
typedef struct bla *bla_t;
then you cannot use it as a constant, such as: const bla_t, because
that constant will be to the pointer itself rather than to the
underlying data. I admit this was a fundamental mistake that must
be corrected.
All typedefs that were pointer types will now have their pointers
removed from the type itself, and the pointers will be used when they
are actually used as variables/parameters/returns instead.
This does not break ABI though, which is pretty nice.
Character conversion functions did not previously ask for a maximum
buffer size for their 'dst' parameter, it's unsafe to assume some given
destination buffer may have enough size to accommodate a conversion.
Just use platform-nix.c code for general stuff that mac is compliant
with, and put a define around everything else. Take that code out of
platform-cocoa.m.
Added os_opendir, os_readdir, and os_closedir to be able to query
available files within a directory.
