Get rid of program and arguments parameters from

methods. Provide a default implementation for start() method.
Introduce virtual doDefaultStart() method, to be called when
default implementation for start() is used() - it's being
triggered by a call to defaultStart(). When some implemetation
provides the custom implemetation of start() method
(e.g. TerminalImpl), the doDefaultStart() may stay unimplemented
(won't be called).
Rename WrongFileNameFailure to WrongCommandFailure, as that's
being used also in case when command arguments parsing failed.

I'd really like to keep/re-enable at least the terminal use
as kind of property not directly tied to the QtcProcess object
life time.
This here is a first step towards this goal (and only a sketch)
I am not sure whether I like using a pointer to a "parent"
data struct as a means to propagate data, but it works, and
it's easy to add a new data item without touching all lower levels.

It may apparently happen that when calling QProcess::start()
we may receive a synchronous signal QProcess::errorOccurred()
from the process we are trying to start. In this case
the handler of the error signal might have removed the
process from m_processes hash, which invalidated the
"Process *& process" reference inside
LauncherSocketHandler::handleStartPacket(). So, using
process reference after calling start() may be dangerous.
Refactor ProcessStartHandler so that it stores the pointer
to the process it handles. The pointer to the handler
should still be valid after calling start(), since
the process itself is being deleted with a delay.
Make ProcessStartHandler a member of ProcessHelper. In this
way it's being reused in QProcessImpl and ProcessLauncher.

Measure it on demand. The printout will appear when
QTC_MEASURE_PROCESS env variable is set. It may be easily
combined with QTC_USE_QPROCESS to compare the time spent
on freezing Creator when starting Creator or when loading
a big project, like Creator project.
In order to compare the measurement between
old implementation (using directly QProcess) and
new implementation (using process launcher) of QtcProcess
do the following (linux):
1. To measure the new implementation:
QTC_MEASURE_PROCESS= ./bin/qtcreator
2. To measure the old implementation:
QTC_USE_QPROCESS= QTC_MEASURE_PROCESS= ./bin/qtcreator
How to measure (two scenarios, A and B):
A. Launch Creator (don't load any project), wait a bit
until all processes finished. Look for the last value
in the 11th column ([A/M] Total Measurement, A means
all measured functions, M means in main thread only).
This value has the greatest influence on GUI freeze -
the higher it is, the longer the GUI is frozen.
Measure it with 1. (new) and 2. (old) implementation
and share your results.
B. Launch Creator and load a Creator project.
Wait until all processes finished (taskbar should be empty).
Look for the last value in the 11th column.
Measure it with 1. (new) and 2. (old) implementation
and share your results.
C* (Additional one)
If only you notice that launching a certain QtcProcess takes
suspiciously too long, replay your scenario that triggers
this process with 1. and 2. and share your results of
the 11th column.

Since e755094480 we have a global option
in Qt Creator to set the (base) environment for any tools run by Qt
Creator. So it is expected that any tool actually uses
Environment::systemEnvironment() as a base, which is the system
environment modified by the global option.
QtcProcess already had a fallback to Environment::systemEnvironment for
resolving environment variables in Qt Creator macros in the command
line. Also use it as a fallback for the actual environment for the
process.
Latest occurrence where the global environment setting was ignored was
for starting language servers by our LSP client.

Fix a race condition in the following scenario:
QtcProcess proc(...)
...
proc.start();
proc.waitForStarted();
if (!proc.waitForFinished()) {
// handle failure here
return;
}
// handle success
Move all the data into the caller's handle
and manage the QtcProcess state only from
inside caller's thread. This eliminates race
conditions when state changed from inside launcher's
thread while the caller's thread isn't notified
immediately.
For example: currently, when the launcher's thread receives
finished signal it doesn't change the process state
immediately, but posts a finished signal to be
dispatched in the caller's thread. When the caller's
thread dispatches the posted signal (inside flush() method)
it changes its state and posts the finished signal to the
outside world.
Don't flush all signals from waitForStarted(). Flush
only started signal in this case.
