btrfs: move the printk and assert helpers to messages.c

These helpers are core to btrfs, and in order to more easily sync
various parts of the btrfs kernel code into btrfs-progs we need to be
able to carry these helpers with us.  However we want to have our own
implementation for the helpers themselves, currently they're implemented
in different files that we want to sync inside of btrfs-progs itself.
Move these into their own C file, this will allow us to contain our
overrides in btrfs-progs in it's own file without messing with the rest
of the codebase.

In copying things over I fixed up a few whitespace errors that already
existed.
