Measure the current transaction time to milliseconds.

Browse Source 
Define a new function, GetCurrentTransactionStartTimeUsec() to get the time
 to this precision.
Allow now() and timestamp 'now' to use this higher precision result so
 we now have fractional seconds in this "constant".
Add timestamp without time zone type.
Move previous timestamp type to timestamp with time zone.
Accept another ISO variant for date/time values: yyyy-mm-ddThh:mm:ss
 (note the "T" separating the day from hours information).
Remove 'current' from date/time types; convert to 'now' in input.
Separate time and timetz regression tests.
Separate timestamp and timestamptz regression test.
