Bump up the heap size to 1MB. With a few kernel modules, libstand
zalloc and userboot seem to want to use ~600KB of heap space, which
results in a segfault when malloc fails in bhyveload.

Clarify comment about default number of FICL dictionary cells.
r241153
Allow the number of FICL dictionary cells to be overridden.
Loading a 7.3 ISO with userboot/amd64 takes up 10035 cells,
overflowing the long-standing default of 10000.
Bump userboot's value up to 15000 cells.

- Missing PTE_SYNC in pmap_kremove caused memory corruption
in userland applications
- Fix lack of cache flushes when using special PTEs for zeroing or
copying pages. If there are dirty lines for destination memory
and page later remapped as a non-cached region actual content
might be overwritten by these dirty lines when cache eviction
happens as a result of applying cache eviction policy or because
of wbinv_all call.

This change was originally intended to account for test kthreads under
the nvmecontrol process, but jhb indicated it may not be safe to
associate kthreads with userland processes and this could have
unintended consequences.
I did not observe any problems with this change, but my testing didn't
exhaust the kinds of corner cases that could cause problems. It is not
that important to account for these test threads under nvmecontrol, so I
am just reverting this change for now.
On a related note, the part of this patch for <= 7.x fails compilation
so reverting this fixes that too.

This patch will save CPU time when the XHCI interrupt is
shared with other devices.
Only check event rings when interrupt bits are set.
Otherwise would indicate hiding possible hardware fault(s).

Use file name hash as a tree key, handle duplicate keys. Both VOP_LOOKUP

entry offset (cookie) is either file name hash or incremental id in case
of hash collisions (duplicate-cookies). Keep sorted per directory list
of duplicate-cookie entries to facilitate cookie number allocation.
Don't fail if previous VOP_READDIR() offset is no longer valid, start
with next dirent instead. Other file system handle it similarly.

This is a horrible hack to get freefall to compile, and is in dire need
of reconciliation. This antique zlib-1.04 code needs to go away.
If the data frame transmission failures, it may have a node reference
that needs cleaning up.
If the frame is marked as M_ENCAP then it should treat recvif as a node
reference and clear it.
Now - since the mbuf has been freed by calling if_transmit() (even on
failure), the mbuf has to be treated as invalid. Hence why the ifp is
used.
If if_transmit() fails, the node ref may need freeing.
This is based on the same logic used by the ageq, which the mesh code
(re) uses for frames which need to be staged before transmitting.
It also does the same thing - if M_ENCAP is set on the mbuf, it treats
the recvif pointer as a node reference and derefs it.
TX stalls in this driver, I've also had some
time to evaluate the effectiveness of different
watchdog strategies.
This is the latest attempt, which consolidates
all of the watchdog logic in one place and
consistently detects TX stalls and resets within
a couple of seconds.

The option is mostly intended as the last-resort when higher pressure
on the vnode cache due to doubling of the vnode counts is not
desirable.
Note that disabling the cache costs more than 2x wall time in the
metadata-hungry scenarious. The default is "cache".
