CVS commit: src/sys

Module Name:    src
Committed By:   pgoyette
Date:           Sat Jun 26 07:23:57 UTC 2010

Modified Files:
        src/sys/kern: init_main.c kern_module.c
        src/sys/sys: module.h

Log Message:
1. Add an allocator for 'struct module *' and use it instead of local

2. Add a new member mod_flags to the 'struct module *' and define
   MODFLG_MUST_FORCE.  If this flag is set and the entry is on the list
   of builtins, it means that the module has been explicitly unloaded
   and any re-loads will require the MODCTL_LOAD_FORCE flag. Provide a
   module_require_force() method to set this flag;  once set, it should
   never be unset.

3. Rename original module_init2() to module_start_unload_thread() to be
   more descriptive of what it does.

4. Add a new module_builtin_require_force() routine that sets the
   MODFLG_MUST_FORCE flag for any module that has not yet successfully
   been initialized.  Call it after module_init_class(MODULE_CLASS_ANY)
   to disable remaining built-in modules.

This makes built-in versions of the xxxVERBOSE modules work once more,
resolving breakage reported by jruoho@ and njoly@.

Discussed on tech-kern, and comments and suggestions implemented.  No
additional discussion for last week.  Tested only on amd64 systems, but
there's nothing here that should be port- or architecture-specific (no
more specific than existing module implementation) so others should not
