Document thread operations

[diversenok]

I wrote some documentation about thread-related functions and types.

Wow, that's some high quality content! Why not add an attribution, something like:

# Documented by
* [diversenok](https://github.com/diversenok)

Of course, it's OK if you prefer to keep it as is.

Also, nit: How about removing the dot from the tables? For example:

.	Query	Set
Type	ULONG or BOOL	N/A
Required access	THREAD_QUERY_INFORMATION	N/A

.               | Query                      | Set
--------------- | -------------------------- | ---
Type            | `ULONG` or `BOOL`          | N/A
Required access | `THREAD_QUERY_INFORMATION` | N/A

Option 1:

	Query	Set
Type	ULONG or BOOL	N/A
Required access	THREAD_QUERY_INFORMATION	N/A

           | Query                      | Set
--------------- | -------------------------- | ---
Type            | `ULONG` or `BOOL`          | N/A
Required access | `THREAD_QUERY_INFORMATION` | N/A

Option 2:

	Query	Set
Type	ULONG or BOOL	N/A
Required access	THREAD_QUERY_INFORMATION	N/A

|                 | Query                      | Set |
| --------------- | -------------------------- | --- |
| Type            | `ULONG` or `BOOL`          | N/A |
| Required access | `THREAD_QUERY_INFORMATION` | N/A |

The second option seems to be more standard:

For compatibility, you should also add a pipe on either end of the row.

Edit: I think adding a pipe just at the beginning is good enough. GitHub docs say "The pipes on either end of the table are optional".

How about removing the dot from the tables?

Yeah, good idea. I updated them.

Why not add an attribution

Well, I don't think it would serve any purpose. Maybe you can add me into the footer later once I document enough functions 😉

A footer is also an option. Feel free to add it to your next PR here and here. Something like "content by diversenok" will work. It might become less manageable if there will be other major contributors, but we can think about it later if it ever happens.
