time handling.  This is more preparation for bug 1616.

foutput_header and moved to ram-output.c.  All callers updated.

(main): Use set_initial_time instead of calling gettimeofday and
accessing current_time directly.
* src/server/ram-output.c, src/server/ram-output.h
(foutput_header): Renamed from sync_output_header.  Use
output_format instead of a hardcoding it to 2.

* src/server/dbck-cache.c (sync_output_header): Use foutput_header
to output a format 2 header.
* src/server/server-time.c: New file.
(current_time): Moved here from ramkomd.c.
* src/server/server-time.c, src/server/server-time.h
