A recent libbcachefs update accidentally committed a change that dropped
the O_DIRECT flag - we definitely didn't want to do that.

Add a new make target to build an rpm. This uses rpmbuild --build-in-place,
so no SRPM is created.
Also clean up the specfile to remove manually-added Requires: that will
be auto-generated, add a couple new BuildRequires: and use macros for
file locations.

- add some project info for the main readme
- migrate readmes to markdown for improved formatting
- The main binary now requires the Rust toolchain, so make note of it
in the build instructions.

This implements BtreeNodeIter, and adds it to cmd_list.rs - the next
step in having a full replacement for cmd_list.c

This implements opt_set!(), which works exactly the same as the C
version and allows filesystem options to be specified in Rust code.

Implement a rust equivalent to bkey_s_c, which uses references with the
correct lifetimes: now cmd_list.rs doesn't need unsafe.

This is a _very_ preliminary rewrite of the cmd_list tool in rust, which
is intended to be a testing ground for a safe interface in Rust to the
core btree interface. This adds rust wrappers for:
bch_fs: provides bch2_fs_open(), bch2_fs_stop
btree_trans: provides bch2_trans_init(), bch2_trans_exit()
btree_iter: provides peek, peek_and_restart, advance
bch_errcode: implements Display (wraps bch2_err_str())
bpos: implements Ord (wraps bpos_cmp())
bkey_s_c: implements Display (wraps bch2_bkey_val_to_text())
and other assorted types.

- passing of arguments from c -> rust code now works correctly
- 'bcachefs mount' now handles being passed a device or devices

Rust is now required for building the bcachefs tool, and rust code is
now fully integrated with the C codebase - meaning it is possible to
call back and forth.
The mount helper is now a subcommand, 'mount.bcachefs' is now a small
shell wrapper that invokes 'bcachefs mount'.
This will make it easier to start rewriting other subcommands in rust,
and eventually the whole command line interface.

cpu_relax() is supposed to be a compiler barrier - this fixes a bug with
btree_write_buffer_flush() getting stuck.

Instead of having to use grep, this adds the ability to print out only
transactions that update a particular key, or to filter out entirely
keys except those updating certain btrees.

remount is handled by libc, not the kernel mount procedure, this fixes
remounts. Also sorted the list of flags.

tracing framework is a overengineered for simple mount helper. Add a
few very barebone logging macros to allow configurable verbosity and
colorized output with a small footprint.
