After changing the namespace.h header we need to provide _err on macOS, too.
Previously we used the system libc err*/warn*, but that does not provide
_err/_warn (which is used by other bootstrapped files from libc).
To fix this problem bootstrap err.c on macOS as well.

The motivation is to provide access to these registers from userspace
via ptrace(2) requests PT_GETDBREGS and PT_SETDBREGS.

This change breaks the ABI of these particular requests, but is
justified by the fact that the intended consumers (debuggers) have not
been taught to use them yet. Making this change now enables active
upstream work on lldb to begin using this interface, and take advantage
of the hardware debugging registers available on the platform.

This is a prerequisite to allowing the use of hardware watchpoints for
userspace debuggers.

This is also a slight departure from the x86 behaviour, since `si_addr`
returns the data address that triggered the watchpoint, not the
address of the instruction that was executed. Otherwise, there is no
straightforward way for the application to determine which watchpoint
was triggered. Make a note of this in the siginfo(3) man page.

In particular, we want to disallow setting breakpoints on kernel
addresses from userspace. The control register fields are validated or
ignored as appropriate.

It does not appear to be required, and as of commit 6b7e592c215f
("lex: Do not let input() return 0 when end-of-file is reached") it
causes input to return 0 instead of EOF when end-of-input is reached.

a further CPU enhancements for compressed acks. These
are acks that are compressed into an mbuf. The transport
has to be aware of how to process these, and an upcoming
update to rack will do so. You need the rack changes
to actually test and validate these since if the transport
does not support mbuf compression, then the old code paths
stay in place. We do in this commit take out the concept
of logging if you don't have a lock (which was quite
dangerous and was only for some early debugging but has
been left in the code).

When executing automount(8), it will attempt to create the directory where an
autofs filesystem is to be mounted. Explicity set the root path for this
directory to "/".

This fixes the issue where the directory being created was being treated as a
relative path instead of an absolute path (as expected).
