Subject: [PATCH 01/12] Log: libcrmcommon: improve description for "not
connected" status
PCMK_EXEC_NOT_CONNECTED was originally added to represent "No executor
connection", but it can also now mean no fencer connection, so change it to
"Internal communication failure" which is probably less mysterious to end users
anyway (especially since it should be accompanied by a more descriptive exit
reason).

Subject: [PATCH 02/12] Refactor: libcrmcommon: drop unnecessary system error
redefinitions
portability.h defines some system error codes that might not be present on
non-Linux systems.
This was a bad idea, since there's no way to ensure the defined values don't
conflict with existing system codes. However, we use a number of them, so it's
probably best to keep them, at least until we can make a backward compatibility
break.
However, we don't use EUNATCH, ENOSR, or ENOSTR, so we can delete those.

Subject: [PATCH 03/12] Log: libcrmcommon: improve handling of portability.h
error codes
portability.h defines some system error codes that might not be present on
non-Linux systems.
Define a constant for each one (for example, PCMK__ECOMM for ECOMM) when
the system doesn't have the value, so we can detect that when relevant.
Also, make sure pcmk_rc_name() and pcmk_rc_str() handle all of these values.

Subject: [PATCH 11/12] Feature: fencing: improve exit reason for fencing
timeouts
Troubleshooting timeouts is one of the more difficult aspects of cluster
maintenance. We want to give as much of a hint as possible, but for fencing in
particular it is difficult because an operation might involve multiple retries
of multiple devices.
Barring another major project to track exactly which devices, retries, etc.,
were used in a given operation, these changes in wording are probably the best
we can do.

Subject: [PATCH 12/12] Feature: libcrmservice: improve exit reason for
timeouts
The services library doesn't have enough information about an action to say
(for example) what configuration parameters might be relevant, but we can at
least distinguish what kind of agent timed out.
