r345675:
fusefs: convert debug printfs into dtrace probes

fuse(4) was heavily instrumented with debug printf statements that could
only be enabled with compile-time flags. They fell into three basic groups:

1. Totally redundant with dtrace FBT probes. These I deleted.
2. Print textual information, usually error messages. These I converted to
   SDT probes of the form fuse:fuse:FILE:trace. They work just like the old
   printf statements except they can be enabled at runtime with dtrace. They
   can be filtered by FILE and/or by priority.
3. More complicated probes that print detailed information. These I
   converted into ad-hoc SDT probes.

Also, de-inline fuse_internal_cache_attrs.  It's big enough to be a regular
function, and this way it gets a dtrace FBT probe.

This commit is a merge of r345304, r344914, r344703, and r344664 from
projects/fuse2.
