Kai Blin 174100c309 popt: Use SMB_CONF_PATH environment var if no other configfile is set.
Now --configfile (or -s) will have precedence, if that's not given
SMB_CONF_PATH is checked, otherwise the $(CONFIGDIR)/smb.conf default
value is used.

Thanks to Michael for his comments.

/**
* @file dynconfig.c
*
* @brief Global configurations, initialized to configured defaults.
*
* This file should be the only file that depends on path
* configuration (--prefix, etc), so that if ./configure is re-run,
* all programs will be appropriately updated. Everything else in
* Samba should import extern variables from here, rather than relying
* on preprocessor macros.
*
* Eventually some of these may become even more variable, so that
* they can for example consistently be set across the whole of Samba
* by command-line parameters, config file entries, or environment
* variables.
*
* @todo Perhaps eventually these should be merged into the parameter
* table? There's kind of a chicken-and-egg situation there...
