Description: searched entry count is logged in the access log as
(nentries=<num>). When RFC 2696 page results control is passed,
the nentries logs the page size instead of the total searched
count.andrey.ivanov(a)polytechnique.fr proposed to log the control
info as follows:
[..] conn=# op=#RESULT err=0 tag=101 nentries=# etime=0 notes=P
This patch implemented the spec.
Also, there was a bug regarding unindexed note "notes=U" when
the paged results control is received. Only the first page logs
it, but not the rest. The bug was fixed.
