This message is only output when a receive operation is cancelled,
so the parameter was always the text "operation aborted" - which
gives no new information.

Documented JSON "schema" for isc::dhcp_ddns::NameChangeRequests
and added explanation of NCR members to D2 doxygen

This is not used in the current version of Kea, although we may use its
code in the future.  Until we decide, the code is being retained in the
repository but it is not included in the build process.

A call to sigaction() is explicitly cast to void to indicate to
static code checkers that the return value is being ignored.

Also modifiy Makefiles to install perfdhcp into sbin.

The messages in question are now output only with logging set to
DEBUG: the DHCP-DDNS process now outputs a minimum number of messages
by default.

Coverity picked up that a construct like "&array[ARRAY_LENGTH]" is
an access to an invalid element, although it is a valid marker
as the end of an STL range.  This change alters that construct
to "array + ARRAY_LENGTH".

Functionally there is no change to the code by this change addresses
the "buffer not null terminated" warning in the logger constructor.
As well as removing the cause of the warning (a "strncpy" where
the length copied is equal to the destination buffer length), it
it removed two assert() calls: one was replaced by the throwing of
am exception, and the second was redundant.

When the configuration file hasn't been specified the server will print
an error message to the stderr and usage. Also I removed the spurious
parens from one of the error messages.

This omission was picked up in review
