sbin/hammer: Assert simplified blockmap allocator
- alloc_blockmap() is a simplified blockmap allocator of
kernel function hammer_blockmap_alloc() as the comment says.
alloc_blockmap() is not aware of layer1 boundary since it
lacks layer1 boundary check and zone wrap check. This still
works for newfs_hammer because it's guaranteed that the newfs
never hits layer1 boundary even in the worst case[*] when
there are 2^8 volumes and each volume is 2^52 bytes storage.
- This commit adds assertions to ensure it's safe to use the
simplified allocator. If a caller hits the assertions then
the program does more than what this allocator supports.
--
[*] In the worst case each volume has 2^(18-8) big-blocks
for layer2 metadata which totals (8[MB] * 1024) = 8[GB].
Other than layer2 metadata, the root volume has 1 big-block
for layer1 metadata, less than 128 big-blocks for undo fifo,
and 1 big-block for btree and meta zone each. These add up
to somewhere between 8-10[GB] but it's still far less than
a single layer1 capacity of 4[TB]. Non-root volumes consume
a bit less than the root volume since it only has layer2
metadata initially which also fits in a single layer1.
The blockmaps for the root and non-root volumes would look
something like the following.
volume#0
zone big-blocks note
==============================================================
4 1 2^18 * layer1 = 2^(18+5) = 8[MB]
4 1024 2^19 * layer2 * 1024 = 2^(19+4+10) = 8[GB]
3 n undo zone for undo fifo (n <= 128)
8 1 btree zone for root btree node
9 1 meta zone for root inode and pfs0
volume#N (0<N<256)

sbin/hammer: Fix wrong free big-blocks counter
- newfs_hammer needs to decrement extra 2 big-blocks from
vol0_stat_freebigblocks for zone 8 and 9.
- newfs_hammer has following three lines that allocate the root
inode, root btree node, and pfs0 metadata for zone 8 and 9,
however because alloc_blockmap() doesn't decrement vol0_stat
_freebigblocks when a blockmap first meets a new layer2,
the volume header shows vol0_stat_freebigblocks 2 more than
it actually is.
bnode = alloc_btree_element(&btree_off, &data_buffer0);
idata = alloc_meta_element(&data_off, sizeof(*idata), &data_buffer1);
pfsd = alloc_meta_element(&pfsd_off, sizeof(*pfsd), &data_buffer2);
- This also means vol0_stat_bigblocks and vol0_stat_freebigblocks
are not equal initially. This commit makes vol0_stat_bigblocks
equal (vol0_stat_freebigblocks + 2), while these two were equal
until this commit. This should make sense than decrementing
vol0_stat_bigblocks by 2 to make these two look the same,
because inodes and btree nodes allocated by regular filesystem
operations do decrement vol0_stat_freebigblocks whenever a new
big-block is allocated and those are counted as used big-blocks.
The initial inode, btree node and pfs shouldn't be an exception.
The diff of hammer info command right after newfs_hammer would
look like this.

sbin/hammer: Remove unnecessary blockmap argument
- format_freemap() does not need the second argument for blockmap.
This function sets that blockmap pointer to
&root_vol->ondisk->vol0_blockmap[4];
right before it starts to initialize blockmap anyway.
- Also passing the freemap blockmap as an argument is redundant
in terms of api since format_freemap() can access the freemap
blockmap via the first argument (root volume, as mentioned above)
given that the function knows it's looking for blockmaps[4].

sbin/hammer: Make function prototype explicit
- format_undomap() is only for root volume, so it's better to have
the same first argument type as format_freemap(). It explicitly
shows that the volume is the root volume.
- Also add assertions to check the given pointer is root volume.
(it's invalid for non-root volumes to call these at least for now)

kernel - Fix panic during coredump
* multi-threaded coredumps were not stopping all other threads before
attempting to scan the vm_map, resulting in numerous possible panics.
* Add a new process state, SCORE, indicating that a core dump is in progress

SSTOP state. SCORE overrides SSTOP.
* The coredump code actively waits for all running threads to stop before
proceeding.
* Prevent a deadlock between a SIGKILL and core dump in progress by
temporarily counting the master exit thread as a stopped thread (which
allows the coredump to proceed and finish).
