[PATCH] http-push: add regression tests

[Clemens Buchacher <drizzd@aon.at>]

http-push tests require a web server with WebDAV support.

This commit introduces a HTTPD test library, which can be configured using
the following environment variables.

LIB_HTTPD_PATH	web server path
LIB_HTTPD_PORT	listening port
LIB_HTTPD_DAV	enable DAV
LIB_HTTPD_SVN	enable SVN
LIB_HTTPD_SSL	enable SSL

Indeed. If Apache or the DAV modules are not found, the test is now skipped. If
Apache is older than version 2, the test is skipped as well. I had some
problems with WebDAV "lock tokens" and couldn't get http-push to work. In
principle, however, lib-http.sh also works with Apache version 1.3.

If LIB_HTTPD_PATH points to an executable, but not to an Apache web server, the
test fails with an error.

Good idea.

I also added SVN support. I simply tried to mimic the code from lib-git-svn.sh.
It should be straightforward to integrate lib-httpd.sh into lib-git-svn.sh now.

Regards,
Clemens
