Update to 4.0.9:

--- 4.0.9 2010/05/21

New utility for managing threads - thread_create.h.

Add socket pipe utility - spipe.h. The socket pipe has same purpose as
Unix pipe . Unfortunately Windows pipes do not work on select/poll -
but YAZ' implementation do.

Fixes for yaz_cond-functions on Windows 7.

DLL export more symbols.

zoomsh: show record do NOT render opac.

Remove *.la files from Debian and RPM packages.

--- 4.0.8 2010/05/11

Debian package libyaz-dev depends on libgnutls-dev again (was
removed in YAZ 4.0.6, but due to Libtool it is still needed
even though yaz-config do not list libgnutls libs).

ZOOM: Use only one WRBUF for returning string results for
ZOOM_resultset. Reduces memory usage for ZOOM in general.

ZOOM: ZOOM_connection do not use a shared pointer to
ZOOM_resultset after ZOOM_resultset is destructed by
user. Reverts to YAZ 4.0.4 behavior.

--- 4.0.7 2010/05/04

record-conv: fix problem with at least one XSL conversion -
due to probably incorrect usage of XML XSL documents.
