824  * Name:	doRemove

827  * Arguments:	a_nodelete: should the files and scripts remain installed?
828  *			- if != 0 pass -F flag to pkgremove - suppress
829  *			the removal of any files and any class action scripts
830  *			and suppress the running of any class action scripts.
831  *			The package files remain but the package looks like it
832  *			is not installed. This is mainly for use by upgrade.
833  *			- if == 0 do not pass -F flag to pkgremove - all
834  *			files and class action scripts are removed, and any
835  *			appropriate class action scripts are run.
836  *		a_altBinDir - pointer to string representing location of the
837  *			pkgremove executable to run. If not NULL, then pass
838  *			the path specified to the -b option to pkgremove.
839  *		a_longestPkg - length of the longest package "name" (for
840  *			output format alignment)
841  *		a_adminFile - pointer to string representing the admin
842  *			file to pass to pkgremove when removing a package from
843  *			the global zone only. Typically the admin file used for
844  *			the global zone is the admin file passed in by the user.
845  *			If this is == NULL no admin file is given to pkgremove.
846  *		a_zoneAdminFile - pointer to string representing the admin
847  *			file to pass to pkgremove when removing the package
848  *			from a non-global zone only. Typically the admin file
849  *			used for non-global zones supresses all checks since
850  *			the dependency checking is done for all zones first
851  *			before proceeding.
852  *			A zoneAdminFile MUST be specified if a_zlst != NULL.
853  *			A zoneAdminFile must NOT be specified if a_zlst == NULL.
854  *		a_zlst - list of zones to process; NULL if no zones to process.
855  * Returns:	int	(see ckreturn() function for details)
856  *		0 - success
857  *		1 - package operation failed (fatal error)
858  *		2 - non-fatal error (warning)
859  *		3 - user selected quit (operation interrupted)
860  *		4 - admin settings prevented operation
861  *		5 - interaction required and -n (non-interactive) specified
862  *		"10" will be added to indicate "immediate reboot required"
863  *		"20" will be added to indicate "reboot after install required"
