Revert the default resource abuse introduced in r104019, which can mask

child logger process failures, by migrating back to 2.0.49 and prior when
rotated logs were reliable on Solaris, etc.

Provides two new piped syntaxes for ErrorLog; "||program" or "|$shellcmd",
where the existing 2.2 behavior may be preserved or the new 2.4 behavior
explicitly elected.  The default should discourage users from "|$" syntax
except as required, in the future.
