internal knowledge that "cd" is a shell's built-in. Such makes
may attempt to exec() "cd" that in turn will fail on systems that
lack the "cd" executable.
Reworked this by eliminating the root cause.

and null-terminated at the same time, because they're later passed to
libjail as null-terminated. That means I also need to add a nul byte when
comma-combining array parameters.

Remove commented out debugs that are no longer useful.
properly parsed for interface prefixes and netmask suffixes. This was
already done for the old-style (fixed) command line, but missed for
the new-style.

Remove a bogus null terminator when stripping the netmask from
IP addresses. This was causing later addresses in a comma-separated
string to disappear.
Use memcpy instead of strcpy. This could just cause Bad Things.

BUS_DMA_COHERENT attribute
The minimum unit for changing "cachable" attribute is page, so call
to pmap_change_attr effectively disable cache for all pages that newly
allocated DMA memory region spans on. The problem is that general-purpose
memory could reside on these pages too and disabling cache might affect
performance. Moreover ldrex/strex operators raise Data Abort exception
when accessing memory on page with "cachable" attribute off.
BUS_DMA_COHERENT does nto require memory to be coherent. It just suggests
to do best effort for reducing synchronization overhead.
PMC_PROC_IS_USING_PMCS macro.
Invocations of this macro are not synchronized with setting/clearing
of P_HWPMC flag, so the atomic operation here isn't needed. Removing
the atomic operation provides noticeable improvement (5-6%) on
some scheduler-intensive workloads with HWPMC_HOOKS enabled on an
8C Sandy Bridge Xeon system.
