869199d992 libsysdecode: Fix decoding of Capsicum rights
Capsicum rights are a bit tricky since some of them are subsets of
others, and one can have rights R1 and R2 such that R1 is a subset of
R2, but there is no collection of named rights whose union is R2.  So,
they don't behave like most other flag sets.  sysdecode_cap_rights(3)
does not handle this properly and so can emit misleading decodings.

Try to fix all of these problems:
- Include composite rights in the caprights table.
- Use a constructor to sort the caprights table such that "larger"
  rights appear first and thus are matched first.
- Don't print rights that are a subset of rights already printed, so as
  to minimize the length of the output.
- Print a trailing message if some of the specific rights are not
  matched by the table.

59838c1a19 Retire procfs-based process debugging.
Modern debuggers and process tracers use ptrace() rather than procfs
for debugging.  ptrace() has a supserset of functionality available
via procfs and new debugging features are only added to ptrace().
While the two debugging services share some fields in struct proc,
they each use dedicated fields and separate code.  This results in
extra complexity to support a feature that hasn't been enabled in the
default install for several years.

is also very handy to have a package that can be tranform to a small mfsroot.
So create a new package named FreeBSD-utilities and make it the default one.
Also move a few binaries and lib into this package when it make sense.

c5c5072bb0 Fix regex for extracting SHM_* values for libsysdecode
There was an additional + after the {6} which is apparently ignored by the
FreeBSD regex implementation but was giving me an error when compiling on
MacOS.

While changing this also make sure that tables.h is not created if mktables
fails. The current rule would create a partial tables.h which causes following
incremental builds to use that broken file and fail with an unrelated
compilation error or even succeed even though they shouldn't.

While there, remove all of the architecture ifdefs. There are not
needed, as the CloudABI data types and system call tables build fine on
any architecture. Building this unconditionally will make it easier to
do tracing for different compat modes, emulation, etc.
