 * Fix the GCC output parser misinterpreting "At top level" messages
   as Errors instead of a simple message.
 * Add unit test to cover this

(cherry picked from commit 1d887410)

 * Fix "instantiated from" with leading spaces being wrongly considered
   an error.
 * Add a unit test to cover this case

 * This is already implicitly tested, but since the reporter
   claims that there was a regression I explicitly added this test.
 * No change needed to make the unit test pass.

... in the ldparser.

Nothing to fix in master, move on;-)

To be reused in the intel linux icpc parser

 * Document the hariest regexp
 * Simplify the parser a bit
 * Catch "/usr/bin/ld: cannot find -lsomelib" (and others)
   as errors.

 * "In blah method " messages are informative, not errors.
 * Be more picky about file names: Stops errors from ranlib, rm,
   etc. being reported as build issues.

 * Also handle TeamBuilder issues similar to QTCB-904

Since otherwise we can't forward declare it.

  ... and add a unit test for it

This reverts commit a797b1f9.

This reverts commit 6b247542.

 * Rework IBuildParser:
    * Remove name() method.
    * Remove enterDirectory and leaveDirectory signals.
    * Allow chaining of parsers.
 * Rename IBuildParser to IOutputParser.
 * Implement GnuMakeParser.
    * Remove entering/leaving directory related code from all other parsers
    * Move filename fixup heuristic based on entering/leaving directory
      massages from gnumake here from AbstractMakeStep.
 * Add outputParser method to ToolChain: This removes the need to map
   toolchains to BuildParser names in the BuildSteps.
 * Enhance AbstractProcessStep to accept a IOutputParser to parse its output.
 * Remove AbstractMakeStep.
 * Set the appropriate Parsers in all classes deriving from AbstractProcessStep
   and append the ToolChain's parser to the parser chain.
 * Remove BuildParserFactories: There is no more need for them.
 * Remove constants used to identify the BuildParsers.
 * Clean up some names:
    * Replace stdOut with stdOutput.
    * Replace addToTaskWindow with addTask and addToOutputWindow with
      addOutput. Do this wherever it is not yet clear that this will end up
      in the Task/Output window.

patch by Robert de Vries

 * Use Task class in addToTaskWindow(...) signal. This introduces
   support for task categories into the BuildParsers.
 * Add a task category for buildsystem issues.
 * Update existing BuildParsers to new API and assign their
   tasks to the Compile or Buildsystem task category.

Always recompile after a rebase :)

The category differs between e.g. TODO tasks, compiler errors/warnings,
qml syntax errrors ... Idea is that every plugin can manage it's
own virtual list of tasks.
