The zfs_dbuf_evict_key TSD (thread-specific data) is not necessary - we can
instead pass a flag down in a few places to prevent recursive dbuf eviction.
Making this change has 3 benefits:
1. The code semantics are easier to understand.
2. On Linux, performance is improved, because creating/removing TSD values
(by setting to NULL vs non-NULL) is expensive, and we do it very often.
3. According to Nexenta, the current semantics can cause a deadlock when
concurrently calling dmu_objset_evict_dbufs() (which is rare today, but they
are working on a "parallel unmount" change that triggers this more easily)

I inadvertently broke 'wc -L' in r326736. We must skip the fast path if -L
was specified, in addition to the existing check for the -l option.
Document long-standing -L behavior (count varies depending on whether wc(1)
is run with the -m option or not) in wc.1. That behavior dates back to the
introduction of the -L option, but was not documented.

9438 Holes can lose birth time info if a block has a mix of birth times
Ultimately, the problem here is that when you truncate and write a file in
the same transaction group, the dbuf for the indirect block will be zeroed
out to deal with the truncation, and then written for the write. During
this process, we will lose hole birth time information for any holes in the
range. In the case where a dnode is being freed, we need to determine
whether the block should be converted to a higher-level hole in the zio
pipeline, and if so do it when the dnode is being synced out.

- Ignore any type of TID where the start/end values are not in the
correct order. There are situations where the firmware isn't able to
reserve room for the number requested in the config file but doesn't
report a failure during configuration and instead sets end <= start.
- Track start/end in tid_tab and remove some redundant copies from
adapter->params.
- Move all the start/end and other read-only parameters to a quiet part
of tid_tab, away from the tid locks.
