DESIRED_TEAMS_PER_MACHINE must equal to DESIRED_TEAMS_PER_SERVER.
Otherwise, we may have to few machine teams to create enough server teams.
Note that BUGGIFY macro value is based on a random number generator.
When you have two BUGGIFY, one may be true and the other is false.
Also fix a bug in get the number of healthy machine teams.
When the total number of teams is larger than the desired number,
we should gracefully remove the redundant teams so that
the number of teams is kept to a low number and the possibility of
losing data is guaranteed to be extremely low even when multiple
racks fail at the same time.
Magnify the possibility that the number of created machine teams is
larger than the number of desired machine teams if we do NOT try to remove the surplus machine teams.
This help test the upgrade to machine team in FDB 6.1
Call the traceTeamCollectionInfo function to record the team numbers
when we add a team directly from the shard information, instead of
using addTeamsBestOf logic.
The current simulator does not validate if the number of teams in
the system is larger than the maximum desired number of teams.
This validation should be added because we do NOT want too many teams
in the system, which may impede the systems availability when
multiple fault zones (e.g., machines) crashes at the same time.
This commit adds the test at the consistency check in simulation.
Since the current code does not handle the upgrading situation
when we enforce the machine teams, the test is expected to fail.
The later commit will handle the upgrading situation which gracefully
remove the surplus teams.
Remove the use of relative paths. A header at foo/bar.h could be included by
files under foo/ with "bar.h", but would be included everywhere else as
"foo/bar.h". Adjust so that every include references such a header with the
latter form.

This takes advantage of the new actorcompiler functionality to avoid
having duplicate definitions of `Void _` when trying to feed the
un-actorompiled source through clang.
canKillProcess logic was wrong.
We still need to configure usable_regions because if datacenterVersionDifference is too large we cannot complete data movement.
* Detail names now all start with an uppercase character and contain no underscores. Ideally these should be head-first camel case, though that was harder to check.
* Type names have the same rules, except they allow one underscore (to support a usage pattern Context_Type). The first character after the underscore is also uppercase.
* Use seconds instead of milliseconds in details.
Added a check when events are logged in simulation that logs a message to stderr if the first two rules above aren't followed.
This probably doesn't address every instance of the above problems, but all of the events I was able to hit in simulation pass the check.
