multipath-tools update Q2/2021

[mwilck]

Hello Christophe,

Here is another PR for multipath-tools. I'd suggest a version bump too, as the diffstat is quite big. The last 3 commits ~haven't been reviewed by @bmarzins yet, they~ are fixups for Ben's latest series.

@bmarzins:

• multipath: print warning if multipathd is not running
• mpathpersist: fail commands when no usable paths exist
• libmultipath: deal with dynamic PTHREAD_STACK_MIN (glibc 2.34)
• cleanups

@xosevp:

• hwtable fixes and additions

@mwilck:

• Improve handling of growing string buffers with the new strbuf API in libmultipath (this represents the bulk of the changes in the PR).
• avoid buffer size warning with systemd 240+
• cleanups, minor fixes
