We duplicate this tracepoint everywhere we call these helpers, so update
the helper to have the tracepoint as well.

Historically we reserved worst case for every btree operation, and
generally speaking we want to do that in cases where it could be the
worst case. However for updating inodes we know the inode items are
already in the tree, so it will only be an update operation and never an
insert operation. This allows us to always reserve only the
metadata_size amount for inode updates rather than the
insert_metadata_size amount.

btrfs_calc_trunc_metadata_size differs from trans_metadata_size in that
it doesn't take into account any splitting at the levels, because
truncate will never split nodes. However truncate _and_ changing will
never split nodes, so rename btrfs_calc_trunc_metadata_size to
btrfs_calc_metadata_size. Also btrfs_calc_trans_metadata_size is purely
for inserting items, so rename this to btrfs_calc_insert_metadata_size.
Making these clearer will help when I start using them differently in
upcoming patches.

This feels more at home in block-group.c than in extent-tree.c.

We have code for data and metadata reservations for delalloc. There's
quite a bit of code here, and it's used in a lot of places so I've
separated it out to it's own file. inode.c and file.c are already
pretty large, and this code is complicated enough to live in its own
space.
