4c0af7a93f bhyve: add wrapper for debug printf statements
Add printf() wrapper to use CR/CRLF terminators depending on whether
stdio is mapped to a tty open in raw mode.
Try to use the wrapper everywhere.
For now we leave the custom DPRINTF/WPRINTF defined by device
models, but we may remove them in the future.

39a5385a74 Add a compact columnar output format, available by specifying a second '-l'
command line option.  Thanks to the removal of unnecessary information and
the organization into columns, this helps the output be more legible on
both 80 column displays and non-80 column displays.  imp@ provided the
idea on this.

b7749b90ee inetd: final round of trivial cleanup, NFC
Highlights:
- Use MAX() for maxsock raising; small readability improvement IMO
- malloc(3) + memset(3) -> calloc(3) where appropriate
- stop casting the return value of malloc(3)
- mallloc(3) -> reallocarray(3) where appropriate

A future change may enter capability mode when forking for some of the
built-in handlers.

93e15ee75e inetd: convert remaining bzero(3) to memset(3), NFC
This change is purely in the name of noise reduction from static analyzers
that want to complain that bzero(3) is obsolete in favor of memset(3).

With this, clang-analyze at least is now noise free. WARNS= 6 also appears
to have been OK for some time now, so drop the current setting and opt for
the default.

9b6286055a inetd: track all child pids, regardless of maxchild spec
Currently, child pids are only tracked if maxchildren is specified. As a
consequence, without a maxchild limit we do not get a notice in syslog on
children aborting abnormally. This turns out to be a great debugging aide at
times.

Children are now tracked in a LIST; the management interface is decidedly
less painful when there's no upper bound on the number of entries we may
have at the cost of one small allocation per connection.

adde65792c cron(8): use proper variable to determine mailer process status
While the mailer is normally opened/set if the mailto is set, this is not
the case if the grandchild actually didn't produce any output. This change
corrects the situation to only attempt to kill/close the mail process if it
was actually opened in the first place.

The reporter initially stumbled on the -n (suppress mail on success) flag
leading to a SIGKILL of the process group, but simultaneously
discovered/reported the behavior with !-n jobs if MAILTO was set and no
output happened.

All of these places that are checking mailto should actually be checking
whether mail is set, so do that for consistency+correctness.

This set of bugs were introduced by r352668.

73773fcda9 fstyp(8): Show exFAT volume labels with -l flag
exfat is fundamentally the same design as fat32.  The superblock differs
marginally, and there are some additional optional features irrelevant to
fstype(8); the structure of dirents has changed slightly to enable, among
other things, larger files; the directory entries are no longer DOS 8.3
ASCII or local 8-bit encoding, but instead explicitly UCS-2-LE.

(As a result, this change uses iconv to convert a found exfat volume label
to the user's locale.)

Locating the volume label is identical to FAT32: locate the root directory
and walk through dirents until you find a volume label.  Like FAT32, follow
the FAT chain between root directory clusters as necessary.

6a9a1b3dee Support software breakpoints in the debug server on Intel CPUs.
- Allow the userland hypervisor to intercept breakpoint exceptions
  (BP#) in the guest.  A new capability (VM_CAP_BPT_EXIT) is used to
  enable this feature.  These exceptions are reported to userland via
  a new VM_EXITCODE_BPT that includes the length of the original
  breakpoint instruction.  If userland wishes to pass the exception
  through to the guest, it must be explicitly re-injected via
  vm_inject_exception().

- Export VMCS_ENTRY_INST_LENGTH as a VM_REG_GUEST_ENTRY_INST_LENGTH
  pseudo-register.  Injecting a BP# on Intel requires setting this to
  the length of the breakpoint instruction.  AMD SVM currently ignores
  writes to this register (but reports success) and fails to read it.

- Rework the per-vCPU state tracked by the debug server.  Rather than
  a single 'stepping_vcpu' global, add a structure for each vCPU that
  tracks state about that vCPU ('stepping', 'stepped', and
  'hit_swbreak').  A global 'stopped_vcpu' tracks which vCPU is
  currently reporting an event.  Event handlers for MTRAP and
  breakpoint exits loop until the associated event is reported to the
  debugger.

  Breakpoint events are discarded if the breakpoint is not present
  when a vCPU resumes in the breakpoint handler to retry submitting
  the breakpoint event.

- Maintain a linked-list of active breakpoints in response to the GDB
  'Z0' and 'z0' packets.

bdad744823 Emulate reads of the PCI command register for passthrough devices.
VFs return zero for the memory enable bit even if it has been set by a
prior write.  After r348779 this caused the annoying behavior that a
guest OS would unintentionally disable memory decoding on a future
read-modify-write operation on the command register.  Instead, return
the shadow value of the command register for reads.  This ensures that
the guest will only toggle the state of the memory enable bit when it
specifically intends to do so.
