timestamp.c
src/include/utils: datetime.h
src/test/regress/expected: interval.out

Log message:
Fix up "Postgres-style" time interval representation when fields have
mixed-signs. Previous effort left way too many minus signs, and was at
least as broken as the one before that :(
Clean up "ISO-style" time interval representation to omit zero fields if
there is at least one non-zero field. Supress some leading plus signs
when not necessary for clarity.
Replace every #ifdef __CYGWIN__ block with a cleaner TIMEZONE_GLOBAL macro
defined in datetime.h.
