(ITS#8118) [PATCH] tool_write_ldif: flush stdout

Full_Name: Thomas Cort
Version: HEAD
OS: Mac OS X 10.10.3
URL: ftp://ftp.openldap.org/incoming/thomas-cort-150429.patch
Submission from: (NULL) (

The LDIF output wasn't being explicitly flushed. In certain scenarios,
such as piping the output of a persistent ldapsearch to node.js v0.12
on Mac OS X 10.10.3, the output is unavailable to the process
consuming the search results until some operating system limit is
reached (8192 bytes for example) and it is automatically flushed.
This can leave the tail end of persistent search results in an operating
system buffer for a long time (until enough output has accumulated
for the OS to flush it).

Explicitly call flush so that the output is immediately available.
