Make timestamp search in org-entry-properties more efficient.
* lisp/org.el: (org-entry-properties) Stop scanning for timestamps if
a specific timestamp property (e.g., DEADLINE, SCHEDULED, etc.) is
requested and a match is found. Also, if a specific timestamp property
is requested, do not push non-relevant timestamps onto property list.
This change only effects org-entry-properties when a specific
timestamp is requested with the special flag, as in:
(org-entry-properties nil 'special "SCHEDULED")
Previously, even if only the SCHEDULED timestamp was requested,
org-entry-properties would parse all the timestamps in an entry. This
extra parsing could slow down the construction of agenda views,
especially with entries that contained a large number of log
items (CLOCK, state changes, etc.). The function org-entry-get,
however, is only interested in the first occurrence of the item. When
looking for a specific type of timestamp, org-entry-properties now
stops searching for timestamps after the match is found, unless the
property is "CLOCK".
