3cfe7ca1a7 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!)

cfcfa3f000 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.

c7d99fe9a7 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.

6d858b63a1 Report percentage complete based on file size 
This patch makes the (reasonable) assumption that the total size of all checked
files fits in a 'long' type.
