More QA Farm fixups and pmOptions changes for libpcp - #2717

…e for OpenIndiana Ordering of candidates packages to pick the latest is secret mumbo jumbo known only to pkg(1).
Resolver differences (not understood) on the new bozo have mean that that an unknown hostname like no-such-host (without any '.'s) returns EAGAIN by some short-circuit logic and never gets to the local bind which would return the EHOSTUNREACH that some QA tests were expecting. Changing to no-such-host.no.such.domain reinstates the original behaviour.
"ORIGIN_TIME" (wrong) -> "PCP_ORIGIN_TIME" (correct)
…isation - resolved some inconsistencies in the ways information is copied (or not) when options are used to populate fields in the pmOptions structure - plugged memory leaks and double free()s introduced in refactorisation - improve coverage in qa/728 - add valgrind dual for qa/728 in qa/1730 (new) - backport libpcp changes to libpcp3
- add some diagnostics - we have some older PCP versions permanently running in the QA Farm now, so some tests need to be a little more careful about which remote host they choose to use - bozo has more CPUs now, so some filter changes needed
1. reset guards to ensure repeated calls are OK 2. remove whacky workaround in src/pmdumptext/pmdumptext.cpp now that libpcp is more well-behaved

Inline comments:
In `@qa/1730`:
- Line 34: Update the QA 1730 flow around ./728 --valgrind to capture and
propagate that command’s exit status into the script’s status variable, so the
existing exit trap returns failures instead of the unchanged success value.
In `@qa/admin/post-setup`:
- Line 913: Update the setup failure exits after the sudo cp/configuration-file
checks to return a nonzero status explicitly, including the corresponding exit
at the second reported location, so callers stop before DNS configuration and
receive failure.
In `@src/libpcp/src/getopt.c`:
- Line 1238: Update pmFreeOptions() to set opts->archives and opts->hosts to
NULL immediately after freeing them, while preserving the existing count resets
so reused options safely pass NULL pointers to realloc().
- Around line 869-875: Update option ownership handling across
__pmStartOptions(), the PCP_ORIGIN_TIME path, and pmFreeOptions(): free owned
allocations for align_optarg, origin_optarg, guiport_optarg, start_optarg,
finish_optarg, and timezone during cleanup, and release any previously owned
setter value before __pmSetOrigin() or other setters overwrite it. Preserve
non-owned opts->optarg values without freeing them.
- Around line 1053-1056: Update the PCP_HOSTZONE debug logging in both
__pmStartOptions implementations to pass the assigned value variable to fprintf
instead of dup_value. Preserve the existing message and branch behavior while
changing both affected sites.
In `@src/libpcp3/src/getopt.c`:
- Around line 868-874: Update the PCP_HOST handling around __pmAddOptHost() to
preserve the duplicated value: remove the immediate free(dup_value), make
__pmAddOptHost() duplicate each argument before storing it in opts->hosts, and
update pmFreeOptions() to release every stored host string.
- Around line 912-1006: Update __pmStartOptions and pmFreeOptions to track
ownership of environment-derived values separately from command-line-backed
pointers, freeing owned align_optarg, origin_optarg, guiport_optarg,
start_optarg, finish_optarg, and timezone allocations during cleanup. Ensure
repeated __pmSetOrigin calls replace and release the previously owned PCP_ORIGIN
value without freeing non-owned command-line pointers.

Release retained environment values during option cleanup.
__pmStartOptions() stores strdup() results in align_optarg, origin_optarg, guiport_optarg, start_optarg, finish_optarg, and timezone. pmFreeOptions() frees only archive and host storage, so these values leak. PCP_ORIGIN_TIME also overwrites the PCP_ORIGIN allocation through __pmSetOrigin().
Track ownership consistently. Free owned values in pmFreeOptions(), and handle previously owned values when setters overwrite them. Do not free non-owned opts->optarg values.

Not all of these have values from *alloc(), so free() is a bad idea.
- bugs in reporting interval (-t) in qa/src/api_abi.c and qa/src/getoptions.c - triggered some remakes - don't call pmFreeOptions() until just befoe exit() as it is now more aggressive with freeing/clearing archives[], narchive, hosts[] and nhost
