RA apache: a major update (closes Bug 1357)

• OCF_RESKEY_testregex: a new parameter
• HTTPDLIST updated to include /usr/sbin/apache and /usr/sbin/apache2
• add '-L' to WGETOPTS
• parsing in awk instead of shell (faster and makes 'sh -x' usable again)
• updated the parser to support the latest apache Include (directories, shell patterns)
• fix a bug triggered if the Listen directive contains only port (the monitor operation)
• the start operation waits indefinitely until the apache really starts; a monitor operation is used to check it; NB: it typically makes at least one loop, thus making the start last for at least a second; the reasoning: user should specify how long a start operation may take
• replace return with exit in the main (i.e. outside of functions)
