bcachefs uses 64 bit inode numbers by default, which overflow genradix
keys when we multiply the inode number by the object size for the actual
genradix lookup.
Switch to a rhashtable, and only index files that actually have
hardlinks.

Add a helper to check for close errrors - especially bad file
descriptors, that can be a fun source of heisenbugs.

Migrate now works: there is an inconsequential free space inconsistency
after marking the new superblock (in migrate_superblock), which we're
hacking around with a fsck.

The copy_data function takes a start and an end parameter as the range
of bytes to copy, but it was called with a start and a length parameter.
This resulted in incomplete file copies. Fix it by passing the end of
the range instead of the length.

This kernel commit: 65bd442397274347e721a89c2c4882a392bae982 removes
BTREE_ITER_cached from bch2_btree_insert_trans, which causes the
update_inode function to take a long time (~20s). Add this flag back in
the update_inode function.

Add a new source command line argument which specifies the directory
tree that will be copied onto the newly formatted bcachefs filesystem.
This commit also fixes an issue in copy_link where uninitialized data is
copied into the symlink because of a round_up of the buffer size.
