Print poll(2) errno

Distinguish between return values -1 (errno set) and 0.

For open/openat, if the flags parameter does not contain O_CREAT, the
3rd (variadic) mode_t parameter is irrelevant. Many developers in the past
have passed mode_t (0, 044, 0644, or such), which might lead future people
to copy this broken idiom, and perhaps even believe this parameter has some
meaning or implication or application. Delete them all.
This comes out of a conversation where tb@ noticed that a strange (but
intentional) pledge behaviour is to always knock-out high-bits from
mode_t on a number of system calls as a safety factor, and his bewilderment
that this appeared to be happening against valid modes (at least visually),
but no sorry, they are all irrelevant junk. They could all be 0xdeafbeef.

Use scan_scaled(3) for memory in ldom.conf

Replace the hand-written routing with a proper library allowing even more
formats.

Since ldomctl's local util.h conflicts with the now used global util.h from
libutil, rename it to ldom_util.h.

Manual wording from amd64's vm.conf(5).

Print LDC protocol version in debug message.

When we nack a domain service because we don't support the requested major
version, provide a major version that we do support.

Check protocol version number before sending an ack indicating that we
support a domain services protocol.

Nack LDC protocol versions that we don't support. Avoids a hang on SPARC T3
systems (and possible newer systems as well).

create xreallocarray() and use it

When opening a /dev/ldom-* device node fails, show its path in the error
message. Tweak error message wording while here for consistency.

Consume ACKs when doing large sends.

Call service start function if a particular domain service has been
successfully registered. Export ds_conn_handle().

Give ldomd(8) its own copy of the domain services support code and modify it
to handle multiple channels. Use it to provide the var-config domain service
to all the currently configured guest domains.
