This is being done to reduce wasted space, simplify complexity in
the code, and to quell a Coverity warning about buffer overruns.

Although it increases the size of the bsnmp{get,set,walk} binaries by
four on my [amd64] system, it removes the need for producing .debug
files, profiled libraries, and for installing the library itself,
reducing the overall size use on disk by the utilities noted
previously.
Plus, it guards against ABI/API compatibility issues with the library
as it's only used internal to the tools themselves.

- snmp_pdu_free should be called before snmp_pdu_create is called
again
- snmp_pdu_free should be called on the resp to snmp_dialog when
successful
Tested with the following bsnmp commands:
% export SNMPUSER=bsnmp SNMPPASSWD=bsnmptest
% SNMP_ARGS="-A proto=sha -C context='' -K -P proto=des -v 3 -r 0"
% bsnmpset $SNMP_ARGS sysLocation="MyAgent"

on the stack
Some of the callers try to determine whether or not `object` is valid by
testing the value for NULL, which will never be true if it's a stack value,
so in order to be clear and correct down the call stack, use a heap
allocated object.
This also addresses a Coverity issue by initializing all of `object` via
calloc

- Set O_CLOEXEC to the signal pipe and /dev/klog.
- Use a single signal handler to catch both SIGHUP and SIGCHLD.
- Fix a bug which did FD_SET() the writer-end of the pipe.
The previous code always set value->v.octetstring.len to len, regardless
of the result from the malloc call. This misleads the caller on malloc
failure. Set .len to len on success and 0 on failure.

r310892 was on the right track, but unfortunately it was resolving
the problem incorrectly and accidentally leaking memory in the
process.
- Call snmp_pdu_free on req before calling snmp_pdu_create on it
at the bottom of the outer while loop
- Call snmp_pdu_free on resp after calling snmpwalk_nextpdu_create
in the inner loop

the main I/O multiplex loop. select() now watches
a pipe which is written by the new skinny signal
handlers and the received signals are handled inside
the loop sequencially.
This eliminates a complex signal mask to guarantee
async-signal safety.
Don't close all file descriptors greater than STDERR_FILENO (2) in
waitdaemon(..) -- only close fd (file descriptor for /dev/null used in
subsequent calls to dup2) if it's greater than STDERR_FILENO.
