If size is 0 after popping data from the front or back, set the
start/end points to 0 as well to ensure that any subsequent buffer
pushes start from the beginning of the buffer rather than the middle of
the buffer. Reduces potential unnecessary operations in that case.
Additionally, this fixes a bug with circulebuf_pop_back where if start
position was 0, and all the data was popped off the buffer (equal to the
capacity), the end position would be equal to the original size. As an
example to replicate the bug, push 5, pop 5, then push 10. The
start/end points will be invalid.

Make sure the target file exists before attempting to create a backup.
This will allow for the function to work correctly if the target does
not yet exist.
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.
When the C header circlebuf.h is used from a C++ source file, this
implicit cast from void to uint8_t* will cause an error unless changed
to an explicit cast.
On MSVC, deprecated types/functions were being completely ignored by the
compiler due to this pragma. Any plugins/programs that depended on this
would also have this warning disabled due to it being in this file.
This pragma was most likely originally done due to the MSVC warnings for
C-standard functions, which are now ignored via _CRT_SECURE_NO_WARNINGS
on all projects instead.
(Note: This commit also modifies the UI)
Being able to generate file names based upon a specification is useful
for more than just the UI; it can also be useful for things such as the
replay buffer where file names need to be generated on the fly.
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.
When it was checking for the BOM at the beginning of the file, it would
just return out of the function if it didn't read at least 3 bytes.
This would particularly affect text sources.
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.

Adds a function to the C-family parser to go to the next token and
create a string copy of it. Useful for when you want to get a copy of
the next token regardless of what type it is.
When the #include directive in in the C lexer preprocessor is
encountered, the files being included need to be relative to the
directory of the file that the include was used in.
