Andrew C. Martin bd0d9b9639 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:

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2160.html
http://stackoverflow.com/q/670308

 - 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
   - fc42fc95 fixes this particular runtime issue for DJGPP & __sun

Thomas Jarosch b1eec7c6b7 Small refactoring to compile more matches
*** Timing of the test suite ***
Four runs were used to calculate the average run time.

Before: ~1,103s
After: ~1,066s
Speed up: 3,35%

*** Timing of internal projects using STL ***
Before: ~8,301s
After: ~8,207s
Speed up: 1,13%

So the real world speed up is roughly 1%.

Andrew C. Martin 4a73c93750 Fix compiler warnings and comment/string typos
- fix g++ warning:

> lib/checkother.cpp:3779: warning: comparison between signed and unsigned integer expressions

 - fix suncc warning (see [everything2](http://everything2.com/title/C%252B%252B%253A+static+extern+%2522C%2522)):

> "lib/checkmemoryleak.cpp", line 578: Warning (Anachronism): Formal argument __compar of type extern "C" int(*)(const void*,const void*) in call to bsearch(const void*, const void*, unsigned long, unsigned long, extern "C" int(*)(const void*,const void*)) is being passed int(*)(const void*,const void*).

- prefer empty() / isEmpty() over "size() > 0" (cases not caught by stlSize)

- fix word misspellings (mostly comments, a few output lines)

  - Parenthesis => Parentheses (both variations were used in the codebase)

  - fix typo and wording ("never alwayw") in gui/test/data/benchmark/simple.cpp's CheckOther::unsignedPositive():

```
-  "An unsigned variable will never alwayw be positive so it is either pointless or "
+  "An unsigned variable can't be negative so it is either pointless or "
```

PKEuS ce961578c2 New checks (inconclusive): Suspicious calculation with sizeof()
- Check for sizeof(ptr)/something: This indicates that programmer was trying to calculate array size, but sizeof(ptr) doesn't return the length of the memory area, but size of a pointer.
- Check for sizeof()*sizeof(): This indicates that programmer misunderstood what sizeof() does: It does return the length in bytes of the given variable, not e.g. the number of elements in an array.

PKEuS 76fbcce13f Restored (intentional) content of screwed up commits 1bcdf4ce3d and 674f7980d519712ff16d8f874dfe55a84deb4b5b:
- New check (Inconclusive): Array filled incompletely with memset/memcpy/memmove
-- This check only warns if the number of elements is given as size in bytes to memset, memcpy or memmove and if the size of an element is larger than 1 Byte. It does not warn for random numbers

- New check: Detect ineffective statements like '*foo++;' (Should be: '(*foo)++;')

Sorry for the inconveniences.

Arpit Chaudhary 7c8da17c44 Added check for detecting if a variable or number is shifted by negative right operand. Statements like:
int i = -1;
 a << i;

 would result in an error message stating undefined behavior.
