Fixed: #31143: please do not use 'Daemon' in the name of daemons. Also removed references to non existing manpages

Removed the misleading statements from getconfent.man that implied the was a globally visible function.  getconfent_r can only be used from within the file CASTOR2/common/getconfent.c

Modified the comment for serrno so that it states that serrno is set to SENOCONFIG when the configuration file cannot be opened.  The previous statement was not 100%, as it implied serrno is to SENOCONFIG only for the condition when the file cannot be found

Added a "multi" version of confent and confent_fromfile that returns the results in an array of strings.
The new functions are confent_multi and confent_multi_fromfile and they both use confent_parser (also new).

to old C style.

internal buffer in thread local storage and call getconfent_r() internally.
