We moved initial list of a pager's caps from ktcb to task's space
since the task is expected to trust its space.
Most references to task->cap_list had to change. Although a single
cap list only tells part of the story about the task's caps, the
TASK_CAP_LIST macro works for us to get the first private set of
caps that a task has.
Removed dependency on hard-coded pager id. Pager id is now passed
as an environment string `pagerid' to tasks. Alternatively, this
could take space in the utcb of each task.
Added UTCB functions for full ipc that copy buffer or string payloads
in secondary message registers.
Some posix syscalls now use these utcb functions to copy pathnames.
test0 now successfully runs its beginning.
test0 SConscript has a dependency problem.
Issues to be investigated:
- vm_file and vnodes need to be merged fully in all functions.
- libposix shared page references need to be removed.
- Any references to VFS_TID, PAGER_TID need to be removed.
container packer picks up files with .elf extentions. Therefore intermediate
files must not have .elf extentions, since they're not meant to go to the final
executable.
