Remove newly unused framework::LockHelper class

Browse Source 
...and make LockHelper::getGlobalLock() FWI_DLLPUBLIC again (so there's a single
such lock, not one per library).

@short helper to set right lock in right situation
@descr This helper support different types of locking:
a) no locks - transparent for user!
This could be useful for simluation or single threaded environments!
b) own mutex
An object use his own osl-mutex to be threadsafe. Useful for easy and exclusiv locking.
c) solar mutex
An object use our solar mutex and will be a part of a greater safed "threadsafe code block".
Could be useful for simulation and testing of higher modules!
d) fair rw-lock
An object use an implementation of a fair rw-lock. This increase granularity of t hreadsafe mechanism
and should be used for high performance threadsafe code!
