Profiling various

writes dictionary with compression

A slight regression in behaviour of the '-profiling' option. Now that memInfo has been made off by default, this command-line option does not enable everything (which would be the expected behaviour).

processor0.log

Why do we see in above log file

profiling::writeNow() at time = 0 profiling::writeNow() at time = 0

?

Status changed to reopened

addProfiling macro does not guarantee destruction at end of scope. If it gets early-deleted it might count completely wrong.

Can output written as a dictionary instead of PtrList? Makes it much easier to manipulate (changeDictionaryDict, foamInfoExec)

Had the idea of writing a dictionary, but there is no natural key other than something like _ID, which seems fairly too arbitrary. As an alternative, could strip out all the non-word chars from the description and try that, but there could be name collisions possible @andy comments?

profiling::writeNow is explicitly called in snappy since there is no natural time-driven triggering of the writeObject mechanism. time = 0 corresponds to the current time.

Do we want to write to stdout? (I understand we want to write the file) i.e. Info<<"profiling::writeNow() at time = " << pool_->owner().timeName() << endl;

If controlDict has profiling {}

decomposePar throws warning

Also, what about situation when the counters exceed label/scalar threshold ?
