Add ETHR_FORCE_INLINE define to hide compiler specific directives

Some win32 specific code does not compile with gcc (mingw-w64) since
'__forceinline' is not supported by gcc. This can be avoided by
defining a new macro ETHR_FORCE_INLINE similar to ETHR_INLINE.

Fix badmatch error when trying to start_link an snmp_test_manager

Was previously unable to start_link an snmp_test_manager due to a
badmatch occurring on line 133.  See traceback here:
http://pastebin.com/1eNYkGTz Edit snmp_test_manager.erl to only expect
the atom ok when it was in turn start_linking an snmpm server.  Also remove reference
to no longer existing Pid variable.  Lastly remove the mgr key from the
State record, as after these changes it was no longer being used.
