719a906ef5 As discussed on tech-kern: mutex_init is too heavyweight for early bootstrap 
phases, so move the initialization of the ksyms mutex back into main via
a function called ksyms_init. Rename the existing (but quite different)
ksyms_init* variations into ksyms_addsyms_elf() and ksyms_addsyms_explicit()
and adapt machdep code accordingly.

4cb83f9c6e Make DDB shows right register values on 32-bit sparc64 kernels. 
- define db_expr_t as int64_t.
- %gsr is 32-bit, so use db_sparc_intop.
- sync arguments with function prototype.
- ansify.

9b58206ecf Some cleanup: 
- When registering command tables, make sure the builtin commands are
   already registered
 - Make the command table entry structure private
 - Do not bother to store the number of commands in a table, we can quickly
   calc that if needed.

463076317b Special case the initialization of builtin command tables to avoid using 
malloc. Fixes PR kern/37042.
Allow "mach" commands registered by LKMs even if there is no builtin
mach command for the arch.

34bb6e19fd Minor clenaup - db_cmd_loop_done is a bool nowadays, so use true/false 
instead of 0/1.

67d703cf25 Import of POSIX Asynchronous I/O. 
Seems to be quite stable. Some work still left to do.

Please note, that syscalls are not yet MP-safe, because
of the file and vnode subsystems.
