Added GC marker change to changelog
The configure tests will not check for functions defined in C99 anymore and C99 compiler support is assumed.
o Removed the GC marker hash table. For types which require GC markers,
they are now allocated as parf of the data type. This significantly
improves GC performance ( up to a factor if 2 in some situations ).
