Apache Developers,

Here is my fifth patch that increases Apache's performance.  This one
eliminates the signal handling associated with graceful restarts.

The inspiration for this patch is the NO_GRACEFUL part of Dean's top
fuel patch
    http://www.arctic.org/~dgaudet/apache/1.3/top_fuel.patch
This patch differs from the NO_GRACEFUL part of Dean's patch in that it
eliminates the variables controlling graceful restart too, and the
unnecessary checks of those variables.

This patch also includes the missing SIGUSR1 manipulation in the new
function quickly_read_request_line() (from patch #2).  When I was
splitting out patch #2 I accidentally omitted that snippet because it
looked like NO_GRACEFUL stuff which was not relevant at the time.
(Really, I am trying to be careful.)

The base for this patch is Apache/1.3.6 + 10x performance increase
patches #1 through #4.

As always, I welcome your review, questions, and feedback.
