Richard Quirk 2ca932a3ae Add checks for explicit constructors
Single-argument constructors should be explicit. Constructors with
multiple arguments should not be marked explicit.

Reijo Tomperi 5e0e2c4782 Fix (Null pointer dereference not detected)

Thomas Jarosch f6e68914ea Add check for cppcheck's internal API usage ()
First checks:
- Simple pattern used inside Token::Match()
- Complex pattern used inside Token::simpleMatch()

The checks get enabled by passing "--enable=internal".
It's not included in "--enable=all".

If you see something that needs further tweaking, just go for it!

Richard Quirk 665cdfabdc Warn when sizeof is used in strncmp ticket
This checks for the case where the user thought sizeof(buf) gave the
size in bytes of 'buf' in code like the following:

  const char *buf = "Hello World";
  strncmp(buf, other, sizeof(buf));

Thomas Jarosch 55d9f0873a Fix (Improve non reentrant function check)
- Use std::map instead of linear std::list walk
  and run fast tests like tok->isName() first.

  Global speed up is 4.8% (profiled with google-perftools)

- Catch function invocations in global namespace
  and ignore other namespaces except "std".

  std::localtime() and others are also non-thread safe on POSIX.

  Note: The check matches f.e. also on "std::getrpcbyname()",
  but that would result in a compile error anyway.
  No need to have an extra "std::xxxxx" whitelist.

- Remove double listed "rand" and "getrpcbyname" function names

Kimmo Varis 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:  (Stop misusing the 'information' error severity!)

Kimmo Varis 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.
