=== Upgrade Process Changes ===
Made /p4/common/bin/p4d/p4/p4broker/p4p shell script rather than binary.
This changes the way SDP new binaries are staged for upgrade. For
safety, exes are now staged to a director outside the PATH, the
/p4/sdp/exes foler. A new 'get_latest_exes.sh' script simplifies
the task of pulling executables from the Perforce FTP server. This
can be used 'as is' for environments with outbound internet access,
and is useful in any case to describe now to acquire binaries.
This addresses an issue where a p4d binary staged for a future
upgrade might be called before the actual upgrade is performed.
* All preflight checks are now done first. Added '-p' to abort after preflight.
* Added '-n' to show what would be done before anything is executed.
* Minimalist logic to start/stop only servers that are upgrade, and apply
upgrades only as needed.
* Staging of exes for upgrade is now separate from /p4/common/bin
* Improved in-code docs, added '-h' and '-man' options.
* Retained pre/post P4D 2019.1 upgrade logic.
