Arithmetic coercion warning

[bozzzzo]

There are a few things in here:

• Long literals are now of type long
• Constructors must now match the name of the class
• @deprecated is implemented for auto-coercion only
• Errors and/or warnings are less likely dropped to the floor

An example of new warnings emitted:

/Users/bozzo/XLII/datawire/reactivesocket/tck/rxlib.q:57:9: warning: constructor name 'RequestResponse' does not match class name 'RequestServer'. Missing return type?
/Users/bozzo/XLII/datawire/reactivesocket/tck/rxlib.q:88:9: warning: constructor name 'RequestClient' does not match class name 'SimpleRequestClient'. Missing return type?
/Users/bozzo/XLII/datawire/reactivesocket/tck/rxlib.q:204:29: warning: Use of deprecated methodmacro '__to_int'. "Long used in integer context will silently truncate the result. Please use truncateToInt() or reverse the operands."
 done.
