Rename Qt logging category: common -> debuggercommon
The old name was too generic and undescriptive. This resulted in
the following confusing lines in KDevelop output:
kdevelop.plugins.common: Change session QObject(0x0) kdevelop.plugins.common: Will reparse arch
MIDebugger: print a specific process error message
Information in the messageboxes is general and sometimes insufficient
to understand why the process could not be started. In such cases
a warning-level error message can be useful. For example:
Debugger ERRORED QProcess::FailedToStart "execvp: Exec format error" Debugger ERRORED QProcess::WriteError "Error writing to process"
GdbDebugger: pass correct string in userCommandOutput()
When Shell script was not empty, both the shell path and the debugger
executable were duplicated in the string sent to userCommandOutput()
because they are prepended to arguments in if(!shell.isEmpty()) branch.
