Wladimir J. van der Laan e07c943ce8 Add AssertLockHeld for cs_main to ChainActive-using functions 
All functions that use ChainActive but do not aquire the cs_main
lock themselves, need to be called with the cs_main lock held.

This commit adds assertions to all externally callable functions
that use chainActive or chainMostWork.

This will flag usages when built with -DDEBUG_LOCKORDER.
