Start a file that would collect tests for I/O functionality of a UDP
socket, targeted on how a socket interacts with userland rather than with
wire side of the protocol.
First version tests that MSG_TRUNC and MSG_PEEK are working correctly.
Any netgraph operation requires root priveleges. Some tests in the
directory already mark themselves with 'atf_tc_set_md_var(conf,
"require.user", "root");' which creates a lot of pasted code. Some tests
don't mark self. For this particular directory a blanket metadata setting
in the Makefile is acceptable, imho.
Some of these fields are specific to Fabrics controllers (such as the
size of capsules) while other fields are shared with PCI-e
controllers, but are more relevant for Fabrics controllers (such as
KeepAlive timer properties).

Add basic CTF support and a CTF-powered pretty-printer to ddb.
The db_ctf.* files expose a basic interface for fetching type
data for ELF symbols, interacting with the CTF string table,
and translating type identifiers to type data.
The db_pprint.c file uses those interfaces to implement
a pretty-printer for all kernel ELF symbols.
The pretty-printer works with symbol names and arbitrary addresses:
pprint struct thread 0xffffffff8194ad90
Pretty-printing currently only works after the root filesystem
gets mounted because the CTF info is not available during
early boot.

When an exception is pending when single stepping we may execute the

could cause the scheduler to fire to run a new thread. This will mean
we single step to a new thread causing unexpected results.
Handle this by masking non-debug exceptions. This will cause issues
when stepping over instructions that access the DAIF values so future
work is needed to handle these cases, but for most code this now works
as expected.
