Add operator detecting for c/cpp

[TOMWT-qwq]

• Add operator detecting for c/cpp.
• Fix FUNCTION_DECLARATION not matching overloading operator.

Changes

• Defined OPERATOR constant and added it somewhere.
• Modified something related to FUNCTION_DECLARATION.

When you say symbol do you mean operator? If so we'd do this by first putting all the operators (including multi-character ones like !=) into an array then using our own regex.either function to build the actual regex.

I cleaned up the PR a bit to better match our coding standards... but I think the reason this hasn't been done before if the issue with <... sometimes it's an operator, sometimes it's the start of a template... so that case would need to be properly handled. (or maybe this will prove to be simpler in C++ since we only use it inside FUNCTION_TYPE_RE)... not sure.

Right now there are a ton of failing markup tests... you'll need to go thru them and see which are operator related (which will simply need to be updated) and which are template related.

There is a line (you can uncomment) in the test/markup test code that will just "replace" the test result files with whatever we generate - it can be helpful for updating result files but if you do this please proof all the changes by hand to guarantee they are as expected.

Nothing is matched according to the tests. Is regex.escape(x) working properly? I can't find its defination from the package downloaded here

[joshgoebel]

So sorry I forgot to push the main file that does the linking... if pull and build it should work now.

[TOMWT-qwq]

ok I'll deal with those tests

[TOMWT-qwq]

It is working now.

You know, a powerful part of hljs is contains: ["self"]. However, a regex is not that powerful. I've tried to do smth, but it doesn't work as expected. I don't think we can recognize everything clearly like a complier now.
