Instead of overloading standard error codes (EINTR/EAGAIN), and defining short lists of error codes in multiple places that potentially end up overlapping & conflicting, we're now going to have one master list of error codes. Error codes are defined with an x-macro: thus we also have bch2_err_str() now. Also, error codes have a class field. Now, instead of checking for errors with ==, code should use bch2_err_matches(), which returns true if the error is equal to or a sub-error of the error class. This means we can define unique errors for every source location where an error is generated, which will help improve our error messages. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

This makes the list of running btree transactions available in debugfs.

This is a highly useful debugging feature but does add a small amount of overhead.

The resulting code will be significantly slower than normal; you

probably shouldn't select this option unless you're a developer.
