Log Message:
update xymon and xymonclient to the current version, 4.3.27

Upstream relnotes:

Changes for 4.3.27
==================

Fixes for CGI acknowledgements and NK/criticalview web redirects.

Xymon should now properly check for lack of SSLv3 (or v2) support at compile-
time and exclude the openssl options as needed.

Completely empty directories (on Windows) are no longer considered errors.

Changes for 4.3.26
==================

This is mostly a bug fix release for javascript issues on the info and
trends pages, along with the enable / disable CGI. Several browsers had
difficulty with the new CSP rules introduced in 4.3.25.

XYMWEBREFRESH is now used as the default refresh interval for dynamic
status pages and various other xymongen destinations. Non-svcstatus
pages can be overridden by altering the appropriate *_header template
files, but svcstatus refresh interval uses this value. (default: 60s)
Set in xymonserver.cfg(5).

Incoming test names are now restricted to alphanumeric characters, colons
dashes, underscores, and slashes. Slashes and colons may be restricted in
a future release.

Unconfigured (ghost) host names are now restricted to alphanumerics, colons,
commas, periods, dashes, and underscores. It is strongly recommended to use only
valid hostnames and DNS components in servers names.

Files matched multiple times by logfetch in the client config retrieved
from config-local.cfg (such as a file matching multiple globs) will now only
be scanned once and only use the ignore/trigger rules from its first entry.
(Note: A future version of Xymon may combine all matching rules for a file together.)

CLASS groupings in analysis.cfg and alerts.cfg will now reliably work for
hosts with a CLASS override in hosts.cfg. Previous, this class was not used
in favor of the class type sent in on any specific client message.
