patch 18-11 compile and numlock fix

[Norbert Federa <nfedera@xxxxxxxxxxxxx>]

hi,

the attached patch fixes the following small problems with 18-11:
o rdesktop must be linked with -lXkb (on my debian box at least)
o ui_sync_lockkeys was not in proto.h
o numlock/capslock sync was not working in some cases(see below)

the numlock sync had no effect if the first event was a 
pointer event in some cases!?
after moving the ui_sync_lockkeys() into the XCheckWindowEvent loop's 
KeyPress case it seemed to work fine.

two questions: 
- any hints for a better place?
- any new information/ideas regarding the server numlock state query
problem?

best regards,
norbert
