589542f50c Remove properties HT from nested GC data 
The properties HT may be a GC root itself, so we need to remove it.
I'm not sure this issue actually applies to PHP 7.2, but committing
it there to be safe. As seen from the test case, the handling here
is rather buggy on 7.2.

38f10ff5cf Fix GC tracing 
Due to the GC changes in 7.3 we stopped tracing most of the
interesting coloring changes...

Prevent the gc_info from becoming all zero for a registered root
by setting the top bit to one for compressed root addresses.

8d3f8ca12a Remove unused Git attributes ident 
The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.

3b5b64ce75 Fix garbage marking in gc_collect_roots() 
gc_collect_white() will mark white nodes as black and add them as
garbage, but only if it's not buffered yet. The already buffered
roots are instead marked as garbage in gc_collect_roots() directly.
However, if gc_collect_white() marked a (buffered) root as black
through recursion, it would not subsequently be marked as garbage.

49ea143bbd Encapsulate reference-counting primitives. 
Prohibit direct update of GC_REFCOUNT(), GC_SET_REFCOUNT(), GC_ADDREF() and GC_DELREF() shoukf be instead.
Added mactros to validate reference-counting (disabled for now).
These macros are going to be used to eliminate race-condintions during reference-counting on data shared between threads.
