Item10069: Web extension installer mis-locates Foswiki root if scripts in cgi-bin

Priority:	CurrentState:	AppliesTo:	Component:	WaitingFor:
Urgent	Closed	Engine	Configure

If Foswiki is installed with an alternate directory structure, the web extension installer mis-locates the Foswiki root

  /ver/www/
    ..  cgi-bin
    ..  htdocs
         .. data
         .. lib
         .. pub

The shell installer when run from "htdocs' works correctly. however the web-based installer executed under the control of cgi-bin/configure and creates a new bin and lib directory beneath /var/www

The issue appears to be that root is assumed to be one level up from the script directory. This is set in lib/Foswiki/Configure/UI.pm

In order to fix this I need a stable definition of $Foswiki::foswikiLibPath. The global is inconsistent. Adding package Foswiki; to setlib.cfg to get a consistent global declaration, and changing references to consistently use $Foswiki::foswikiLibPath

Also fixing a small issue with Util::mapTarget. Matching on /bin scripts missed scripts named with multi-word names, such as foswiki.fcgi

Even with fixing lib to map to $Foswiki::foswikiLibPath, any other unknown directories distributed by an extension will be placed into a directory one level up from the "bin" directory. This is incorrect on many installations.

After some IRC discussion, the Foswiki root (for installing extensions) should be one-level-up from {dataDir} or {toolsDir}. {pubDir} is possibly located in a webroot, $Foswiki::foswikiLibDir might be relocated into perl, and bin might be in cgi-bin above the webroot.
