-Add support for use of the system timezone database, rather
-than embedding a copy.  Discussed upstream but was not desired.
-
-History:
-r7: improve check for valid timezone id to exclude directories
-r6: fix fd leak in r5, fix country code/BC flag use in 
-    timezone_identifiers_list() using system db,
-    fix use of PECL timezonedb to override system db,
-r5: reverts addition of "System/Localtime" fake tzname.
-    updated for 5.3.0, parses zone.tab to pick up mapping between
-    timezone name, country code and long/lat coords
-r4: added "System/Localtime" tzname which uses /etc/localtime
-r3: fix a crash if /usr/share/zoneinfo doesn't exist (Raphael Geissert)
-r2: add filesystem trawl to set up name alias index
-r1: initial revision
