Add new "style" check to catch redundant pointer operations
...
Doing "&*some_ptr_var" is redundant and might be the remainder
of a refactoring. Warnings for expanded macros are excluded though:
They are often used with and without pointers and
do something like this: "func(&(*macroarg))".
The new check is fully AST based and was given
strong false positive testing on a large code base.

fix misspellings & gcc v3.4.6 warnings
...
1. fix typos / misspellings
- Fix misspelling within comments, variable/function names, stdout messages
- changes the name of an error code: ```stlBoundries``` changed to ```stlBoundaries```. Alias old name (```stlBoundries```) to the new one.
2. fix gcc v3.4.6 32bit & 64bit warnings
- fixes gcc v3.4.6 warnings, except for those in tinyxml and "-Wmissing-declarations" makefile warnings
- in Preprocessor::handleIncludes(), replace a ```vector <bool>``` with ```stack<bool>``` (see ```vector<bool>``` warning below).
- this is the only ```vector<bool>``` in the codebase
- ```vector <bool>``` is actually a case of template specialization, and is not recommended, according to the following links:

- in the codebase before and after this change, testrunner SEGVs in a number of places on gcc v3.4.6, including ```Check::~Check()```, among others

Move "information" errors to "style" errors.
...
"information" severity is documented in lib/errorlogger.h as:
Checking information.
Information message about the checking (process) itself. These
messages inform about header files not found etc issues that are
not errors in the code but something user needs to know.
It IS NOT for errors in the code. All the current "information"-
severity errors fit nicely into description of the "style"-
severity.
We definitely need to separate processing information and actual
errors in the code. It is highly confusing for users to mix these
two different things. Hence all current "information" code error
messages are moved to "style" category.
Ticket: #3165 (Stop misusing the 'information' error severity!)

Use "enabled" list for the style checking.
...
Settings-class currently enables style checking via dedicated
boolean attribute. All other CLI's enable-options are handled
through the enable-list. This commit moves style-check enabling
to use the enable-list.
Main advantage is the consistency how options are handled/stored
in the Settings class. Which also unifies using them for the other
code. You need to enable certain type of checks? Use the
addEnabled()-method. You want to check if certain type of checks
are enabled? Use the isEnabled()-method.

Remove ErrorLogger::reportStatus() method.
...
The ErrorLogger::reportStatus() is not lib code interface. The CLI
code does the looping through file list and gives one file at a
time for the core code. Hence lib has no any idea about the
progress and it can't provide such information.
Also the recent commit (6d858b6
) caused a GUI build failure by
adding CLI code dependency to GUI. Which is big no-no.
This is admittedly a hack. But it allow us to build all modules
again.
