...to free some memory.
The translation units of the 7 most recently used documents ("hot
documents", tracked by document visibility) are kept in memory.
Translation units of other documents are suspended and will be resumed
once they become visible again.
The resumption of a translation unit needs the same time as reparse
(since it is a reparse effectively).
The number of hot documents can be modified by the run time environment
variable QTC_CLANG_HOT_DOCUMENTS=N. Visible documents are always hot.

This simplifies the high level client ClangCodeModelServer and removes
quite some duplication in tests.

This could happen, e.g. with this message order:
>>> updateTranslationUnitsForEditor()
add job<1>
run job<1>
>>> updateVisibleTranslationUnits(Utf8String(), {})
>>> updateVisibleTranslationUnits(path, {path})
add job<2>
finish job<1>
run job<2> -- Ops, nothing is changed but job<2> is started
This led to an outdated translation unit (e.g. wrong highlighting).
Now JobQueue checks for duplicates in the queue and checks all the
currently running jobs.

Parsing happens rotationally on the translation units.
The recently parsed translation unit is used for completion jobs while
the older version is used for parse jobs.
Advantages:
A1. A completion job cannot be blocked anymore by currently running
parse job.
A2. Faster triggering of parse jobs. A reparse was triggered about
1650ms after the last keystroke. This is down to 500ms now since we
do not have a blocking translation unit for the completion anymore.
Disadvantages:
D1. Memory consumption is doubled for an edited document.
This could be addressed by suspending the second translation unit
after some time of inactivity.
D2. Setup of the supportive translation unit takes some time.

This enables a job per translation unit instead of per document.
This does not change any behavior yet.

Speed ups the typical use cases that can profit from this:
* Change a header file and switch then to source file
* Open documents one after the other (Follow Symbol)
* Change documents visible in splits (e.g. by refactoring action)
* Restore a session with multiple splits
Fixes the test ClangIpcServer.GetCodeCompletionDependingOnArgumets.
