time conversion factor for now).

We can't handle an allocation failure there (at least for now). Took the chance to stylize the code.

for temporary memory anymore, it's the store's responsibility to do that
correctly now, and that functionality is reached via the vm_cache using
vm_cache_set_minimal_commitment().
Therefore, the vm_store commit() function now returns a status instead of
the size that could be commited.
Replaced the max_commit mechanism with one that cares about the available
memory, stores can reserve and unreserve such memory. The anonymous_commit()
will now fail in case it could not reserve the needed amount of memory.

add_partitions_for(), though).
The partition now also tracks if it refers to a partitioning system or not.

- only one byte was being used for total data length in a data field
which had 'maxi' size data (total data > 255 bytes), rather than the
correct four bytes.
- Seem to have finally nailed the proper algorithm for calculating data
item padding (four size bytes + bytes of data, padded to 8-byte
boundary) in all places.
- Was passing the address of the padding string, rather than the string
itself, when writing out NULL padding bytes
- Was incorrectly clearing the MSG_FLAG_MINI_DATA bit when the number of
data items or the size of the largest data item exceeding 256 bytes.
Bit is now cleared when total size of all item data (including size
bytes and padding, if applicable) exceeds 256 bytes
- Modified SizePolicy::Padding(const T&) to use calc_padding() from
MessageUtils.h/.cpp
- Added SizePolicy::Padding(const Store&) to calculate padding for data
field's entire data store

* Added resolve_mount_point_to_volume_root() which does what
resolve_volume_root_to_mount_point() did. IOW the latter one didn't
do what it advertised.
* Fixed dir_vnode_to_path(). Basically broken due to the broken
resolve_volume_root_to_mount_point(), but also compared potentially
unrelated vnode IDs (belonging to different volumes).
* Fixed get_dir_path_and_leaf(). It didn't deal correctly with paths
ending in '/' (including the root dir).
* fs_mount() does now accept a NULL fsName, getting the FS name from
the DDM in this case.
* fs_mount() now also supports mounting file images; it lets the DDM
create a file device for them.

done by (currently not existing) devfs functions.
* Overridden GetMediaStatus() and GetGeometry() to return useful data.

* Made GetMediaStatus() a bit more robust. If the ioctl fails (e.g. if it
is not implemented as in Thomas' drivers), it gets the device geometry
and does not fail, if the device is not removable.

the ReadFrames call no longer needs to wait for the
extractor, but can read it from a cache.

and why they are called.
Introduced a cpu_init_post_vm() that will now call arch_init_post_vm() instead
of letting main() doing it.
Fixed some return types (mostly from int to status_t).

- the above file now also exports a function to finally complete the kernel's
address space translation map after semaphores became available (was just
not done before)
- renamed some functions, especially the *_init2() functions are now called
like *_init_post_area() to indicate they are called after the area functionality
became available
- removed the _struct suffix from certain structures
- fixed some return types
- added prototype for vm_free_unused_boot_loader_range() to be called by
arch code.

Removed the "str" field I have no idea what it could have been useful for.
Changed the frame buffer part of the kernel args - "already_mapped" is
no longer there, as it doesn't make a lot of sense.

Changed team_remove_team() to support process groups.
Added new prototype for team_delete_process_group().

Moved the dead_children stuff into a sub-structure.

Changed the way a dying thread propagates its exit status and reason: we
no longer abuse the semaphore mechanism to carry an extra status value,
instead, wait_for_thread() registers a death_entry with the thread that
will be filled upon exit.

This cleans the page handling when having to make an area copy-on-write;
regions belong to vm_cache_ref, pages to vm_cache.
Added prototype for new call vm_copy_area().
Fixed some return types.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9263 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed the way a vm_address_space is deleted: instead of having to explicitly
call vm_delete_aspace(), the last vm_put_aspace() will remove it.
