Update ap-jk to 1.2.22.

Changes between 1.2.21 and 1.2.22

Native
 Refactor line endings logging to make it correct for all platforms and \ 
webservers. (mturk)
 Added command line windows make files. (mturk)
 Allow fail_on_status directive to be multi line. (mturk)
 42076: Fix name of new option from ForwardCertChain to ForwardSSLCertChain as \ 
documented. (rjung)
 Docs: Fix a couple of typos, change format of a few tables, fix links to news \ 
pages. (rjung)
 Fix correct URL for TC 6 examples in new IIS rewrite.properties configuration \ 
example file. (rjung)
 Add svn properties to several files. (rjung)
 Add TC 6 examples to uriworkermap.properties in config examples. (rjung)
 Allow multiple status codes for fail_on_status directive. The status codes can \ 
be delimited by space or comma characters. (mturk)
 IIS. Added pcre like regular expressions for url rewrite rules. (mturk)
 41922: Apache 1.3. Enable JkEnvVar. (mturk)
 Apache. Add --enable-flock configure parameter for explicit compilation of \ 
faster flock() system calls for OS supporting those calls. By default the fcntl \ 
system call for locking will be used that is a little bit slower but it can work \ 
on NFS mounted volumes as well. (mturk)
 41562: Add Debug logging for read from client in ISAPI Redirector. Contributed \ 
by Tim Whittington. (mturk)
 Apache. Add ForwardSSLCertChain JkOption. Contributed by Patrik Schnellmann. (mturk)
 IIS. Do not forbid access to web-inf or meta-inf if there is no mapped worker. \ 
This allows to have resource with those names that are outside mapped contexts. \ 
(mturk)
 Apache. Use process id for creating shared memory name and delete shared memory \ 
and shared memory lock files on exit. (mturk)
 IIS. Fix Keep-Alive regression introduced in 1.2.21. (mturk)
 Delete unused check for empty init_map during startup. (rjung)
 41770: Fix startup error if no JkWorkersFile is used. (rjung)
 Use JK_TRUE/JK_FALSE instead of OK/!OK as return values in init_jk(). (rjung)
 Minor adjustments to apache startup log messages (when to use STDERR, remove \ 
deprecated NOERRNO flag, shm warning and warnings for usage of default files). \ 
(rjung)
 Replace APR precompiler directive by httpd mpm_query to detect MPM threading. \ 
Add a debug log message about auto-detected pool size. (rjung)
 Make MMN check easier to understand and a little more precise (for new \ 
ap_get_server_banner()/ap_get_server_description()). We use the new API only for \ 
Apache httpd 2.3. This way our binaries are not tightly coupled to a minor 2.0 \ 
version, and we don't use ap_get_server_banner() any way. (rjung)
 Use the full description string ap_get_server_description() instead of the \ 
truncated info from ap_get_server_banner(), because this info gets used \ 
internally (status worker display and ajp14 backend communication) and is not \ 
send back to the normal user. (rjung)
 41757: Document the "--enable-prefork" flag of configure. (rjung)
 Enhance log messages for failures when parsing attribute maps. (rjung)
 Correct log message during worker initialization, in case remote host could not \ 
be resolved. We logged the default host name "localhost" instead of \ 
the configured one. (rjung)
 41770: Fix the second part of the bug: local_worker and local_worker_only is \ 
missing from the list of deprecated attributes (and not supported either), so \ 
prevents the web server from startup. (rjung)

Changes between 1.2.20 and 1.2.21

 CVE-2007-0774 : A denial of service and critical remote code execution \ 
vulnerability. Caused by buffer overflow in map_uri_to_worker() when URL were \ 
longer that 4095 bytes. Reported by ZDI (www.zerodayintiative.com). Please note \ 
this issue only affected versions 1.2.19 and 1.2.20 of the Apache Tomcat JK Web \ 
Server Connector and not previous versions. Tomcat 5.5.20 and Tomcat 4.1.34 \ 
included a vulnerable version in their source packages. Other versions of Tomcat \ 
were not affected.
 Check the worker. parameters and don't start if the parameter is not a valid \ 
one. (jfclere)
 41439: Allow session IDs to get stripped off URLs of static content in Apache \ 
by adding JkStripSession directive (configurable per vhost). (mturk)
 Change semantics of empty defaults for JkEnvVar variables. Until 1.2.19: not \ 
allowed. In 1.2.20: send variables as empty strings, if neither set to non empty \ 
in config, nor during runtime. Starting with 1.2.21: If config has no second \ 
argument only send variable if set (even when set to empty string) during \ 
runtime. Allows good combination with condition attribute in tomcat access log. \ 
(rjung)
 41610: Fix incorrect detection of missing Content-Length header leading to \ 
duplicate headers. Contributed by Boris Maras. (rjung)
 Better build support for SunONE (Netscape/iPlanet) webservers. (jim)
 Add warning if duplicate map keys are read and are not allowed, e.g. when \ 
parsing uriworkermap.properties. (rjung)

instead overwrite the worker. (rjung)
 Log deprecation message even in duplication case. (rjung)
 uriworkermap.properties: Fix off-by-one problem when deleting URL mapping \ 
during reloading of uriworkermap.properties. (rjung)

insensitive. (rjung)
 JkStatus: Add estimated time until next global maintenance to other mime types \ 
and adopt jkstatus ant task. (rjung)
 JkStatus: Show estimated time until next global maintenance. Change displayed \ 
time until next recovery to a min/max pair. (rjung)
 JkStatus: Allow a user of a read/write status worker to switch it to and from \ 
read_only mode temporarily. (rjung)
 JkStatus: Do not show read/write commands in a read_only status worker. (rjung)
 JkStatus: Allow lb sub workers in error state to be marked for recovery \ 
administratively from the status worker. (rjung)
 Load Balancer: Do not try to recover multiple times in parallel. Use additional \ 
runtime states "PROBE" and "FORCED". (rjung)
 JkStatus: Improve data synchronization between different processes. (rjung)
 41381: Fix segfault in feature fail_on_status (wrong order of log arguments). \ 
Patch by Juri Haberland. (rjung)
