We can read fs_info from extent buffer and can drop it from the
parameters.

By function, chunk item verification is more suitable to be done inside
tree-checker.
So move btrfs_check_chunk_valid() to tree-checker.c and export it.
And since it's now moved to tree-checker, also add a better comment for
what this function is doing.

Remove GPL boilerplate text (long, short, one-line) and keep the rest,
ie. personal, company or original source copyright statements. Add the
SPDX header.
Unify the include protection macros to match the file names.

When inspecting the error message with real corruption, the "root=%llu"
always shows "1" (root tree), instead of the correct owner.
The problem is that we are getting @root from page->mapping->host, which
points the same btree inode, so we will always get the same root.
This makes the root owner output meaningless, and harder to port
tree-checker to btrfs-progs.
So get rid of the false and meaningless @root parameter and replace it
with @fs_info.
To get the owner, we can only rely on btrfs_header_owner() now.

[BUG]
If we run btrfs with CONFIG_BTRFS_FS_RUN_SANITY_TESTS=y, it will
instantly cause kernel panic like:
------
...
assertion failed: 0, file: fs/btrfs/disk-io.c, line: 3853
...
Call Trace:
btrfs_mark_buffer_dirty+0x187/0x1f0 [btrfs]
setup_items_for_insert+0x385/0x650 [btrfs]
__btrfs_drop_extents+0x129a/0x1870 [btrfs]
...
-----
[Cause]
Btrfs will call btrfs_check_leaf() in btrfs_mark_buffer_dirty() to check
if the leaf is valid with CONFIG_BTRFS_FS_RUN_SANITY_TESTS=y.
However quite some btrfs_mark_buffer_dirty() callers(*) don't really
initialize its item data but only initialize its item pointers, leaving
item data uninitialized.
This makes tree-checker catch uninitialized data as error, causing
such panic.
*: These callers include but not limited to
setup_items_for_insert()
btrfs_split_item()
btrfs_expand_item()
[Fix]
Add a new parameter @check_item_data to btrfs_check_leaf().
With @check_item_data set to false, item data check will be skipped and
fallback to old btrfs_check_leaf() behavior.
So we can still get early warning if we screw up item pointers, and
avoid false panic.

It's no doubt the comprehensive tree block checker will become larger,
so moving them into their own files is quite reasonable.
