Added the following utility methods to VarDecl that provide
...
canonicalized queries of a variable's storage:
hasAutoStorage - Does a variable have (implicit) auto storage?
hasStaticStorage - Does a variable have (implicit) static storage?
hasLocalStorage - Is the variable a non-static local variable?
hasGlobalStorage - Is the variable a global variable or a static
local variable?
Additional comments documenting these functions are included in the
source.

Added support for additional format string checking for the printf
...
family of functions. Previous functionality only included checking to
see if the format string was a string literal. Now we check parse the
format string (if it is a literal) and perform the following checks:
(1) Warn if: number conversions (e.g. "%d") != number data arguments.
(2) Warn about missing format strings (e.g., "printf()").
(3) Warn if the format string is not a string literal.
(4) Warn about the use se of '%n' conversion. This conversion is
discouraged for security reasons.
(5) Warn about malformed conversions. For example '%;', '%v'; these
are not valid.
(6) Warn about empty format strings; e.g. printf(""). Although these
can be optimized away by the compiler, they can be indicative of
broken programmer logic. We may need to add additional support to
see when such cases occur within macro expansion to avoid false
positives.
(7) Warn if the string literal is wide; e.g. L"%d".
(8) Warn if we detect a '\0' character WITHIN the format string.
Test cases are included.
