Re-introduce another part of r249367. This commit fixes a register leak in
dt_cg_ptrsize() and generally cleans up some of the error handling around
register allocation.

This change corresponds to part of illumos-gate commit e5803b76927480:
  3025 register leak in D code generation

Add a comment explaining why stack_capture is empty for EABI and clang.

While here add a comment pointing out that, while r11 is not the frame

safe.

Initialize the fibnum for outgoing packets to 0. This avoids

Remove lint case for _Thread_local.

I added this block, knowing that lint does not support _Thread_local.
When linting, we could argue that we don't care about TLS (yet). It
seems, however, that external pieces of software also sometimes do a
-Dlint, regex the output and compile it again.

Refine the "nojail" rc keyword, adding "nojailvnet" for files that don't

Be (very) careful about how to add more TX DMA work.

The list-based DMA engine has the following behaviour:

* When the DMA engine is in the init state, you can write the first
  descriptor address to the QCU TxDP register and it will work.

* Then when it hits the end of the list (ie, it either hits a NULL
  link pointer, OR it hits a descriptor with VEOL set) the QCU
  stops, and the TxDP points to the last descriptor that was transmitted.

* Then when you want to transmit a new frame, you can then either:
  + write the head of the new list into TxDP, or
  + you write the head of the new list into the link pointer of the
    last completed descriptor (ie, where TxDP points), then kick
    TxE to restart transmission on that QCU>

* The hardware then will re-read the descriptor to pick up the link
  pointer and then jump to that.

Now, the quirks:

* If you write a TxDP when there's been no previous TxDP (ie, it's 0),
  it works.

MFC r249625:
Introduce kern.timecounter.smp_tsc_adjust tunable (disabled by default) and
respective functionality, allowing to synchronize TSC on APs to match BSP's
during boot.  It may be unsafe in general case due to theoretical chance of
later drift if CPUs are using different clock rate or source, but it allows
to use TSC in some cases when difference caused by some initialization bug,
while TSCs are known to increment synchronously.

MFC r248552, r248971

Add ipfw support for setting/matching DiffServ codepoints (DSCP).

Setting DSCP support is done via O_SETDSCP which works for both
IPv4 and IPv6 packets. Fast checksum recalculation (RFC 1624) is done for IPv4.
Dscp can be specified by name (AFXY, CSX, BE, EF), by value
(0..63) or via tablearg.

Matching DSCP is done via another opcode (O_DSCP) which accepts several
classes at once (af11,af22,be). Classes are stored in bitmask (2 u32 words).

Add a new set of notes to a process core dump to store procstat data.

The notes format is a header of sizeof(int), which stores the size of

The userland tools (procstat(1)) will be taught to extract this data,
providing additional info for postmortem analysis.
