This fixes truss when built as part of a riscv64sf world. Additionally,
if FreeBSD ever supports RV32 RISC-V most of this file can be used as-is
just as a single file is used for all of the MIPS ABIs.
Sponsored by: DARPA
Summary:
Currently, truss doesn't work on ELFv2 processes due to not recognizing the ABI.
Since there's no special handling needed here, just adding a PROCABI struct for
it is sufficient to get it working.

Some options come from static constructors in LLVM libraries and are
automatically added to llvm's usage output. They're not really supposed
to be llvm-objdump options.

Some options appear in llvm-objdump's usage information as a side effect
of its option parsing implementation and are not actually llvm-objdump
options. Reported in LLVM review https://reviews.llvm.org/D54864.

Based on llvm-objdump's online documentation and usage information.
This serves as a starting point; additional detail and cleanup still
required.
Also being submitted upstream in LLVM review D54864. I expect to use
this bespoke copy while we have LLVM 6.0 or 7.0 in FreeBSD; when we
update to LLVM 8.0 it should be upstream and we will switch to it.

Under some conditions pom would report "waning" and then "full", show
higher percentages than it should, and get confused by DST. Fix.

We want to encourage our users to upload their dmesgs so that the project can
get a better insight into what kind of hardware is run on. This helps in making
data-driven decisions about i.e., platform and driver support.
Note that dmesgs may contain sensitive information like hardware serial numbers,
hence uploading them without review is discouraged.

llvm-profdata is used with llvm-cov for code coverage (although llvm-cov
can also operate independently in a gcov-compatible mode).
Although llvm-profdata can be used independently of llvm-cov it makes
sense to group these under one option.
Also handle these in OptionalObsoleteFiles.inc while here.

Support a "live" mode in ktrdump enabled via the -l flag. In this
mode, ktrdump polls the kernel's trace buffer periodically (currently
hardcoded as a 50 millisecond interval) and dumps any newly added
entries. Fancier logic for the timeout (e.g. a command line option or
some kind of backoff based on the time since the last entry) can be
added later as the need arises.
While here, fix some bugs from when this was Capsicum-ized:
- Use caph_limit_stream() for the output stream so that isatty() works
and the output can be line-buffered (especially useful for live
mode).
- Use caph_limit_stderr() to permit error messages to be displayed if
an error occurs after cap_enter().
