IIUC, the (c) has no meaning.

When admin commands control health, we report the timestamp of that
override operation.

When probing controls health, we report the timestamp of last
probing state change.

Otherwise, we report the timestamp of last admin health command.

expose it in the public side of the API so the backend layer
can get at it.

Technically it can also happen with a debugger attached to a process
despite SA_RESTART.

It was either this or adding a suppression for lsan.

Spotted by lsan.

Otherwise any futile attempt at disabling developer warnings (even
temporarily) will be neutered by the distcheck target.

This is a temporary measure until #3565 is solved.

This reverts commit 2baff3dc.

This reverts commit 05780b63.

If we have to choose between this warning and alpine being part of our
CI, this warning takes precedence. It's always possible to disable
developer warnings on CCI if that's a problem with musl then we can
configure its CCI job to disable developer warnings.

The +table flag causes all overlapped ACL entries to be compiled
as usual, and non-overlapped entries to be emitted as a table of
bytes.

When testing the ACL the compiled code is run before VPI_acl_table()
is used to do a binary search on the table.

Even with a binary search, the table is approx 3 times slower than
the regular compiled ACLs (ie: only "blindingly fast" as oppposed
to "lighting fast").

The advantage of +table is that C-compilers literally take no time,
no matter the size of the ACL, where they will take seconds
or even minutes compiling large ACLs as code.

Fixes #3571

Closes: #3570

We used the -t argument only for the VSM attach, not for the actual CLI
operations.

I do not think the complication of differentiated timeouts is justified,
so just use the one timeout parameter we have for both. Also I think
that the documentation is already adequate in its simplicity:

       -t timeout
              Wait no longer than this many seconds for an operation to
              finish.

Fixes #3542
